Detailed Description

The following description of the embodiments of the present application is provided for illustrative purposes, and other advantages and capabilities of the present application will become apparent to those skilled in the art from the present disclosure.

In the following description, reference is made to the accompanying drawings that describe several embodiments of the application. It is to be understood that other embodiments may be utilized and that mechanical, structural, electrical, and operational changes may be made without departing from the spirit and scope of the present disclosure. The following detailed description is not to be taken in a limiting sense, and the scope of embodiments of the present application is defined only by the claims of the issued patent. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. Spatially relative terms, such as "upper," "lower," "left," "right," "lower," "below," "lower," "above," "upper," and the like, may be used herein to facilitate describing one element or feature's relationship to another element or feature as illustrated in the figures.

Although the terms first, second, etc. may be used herein to describe various elements or parameters in some instances, these elements or parameters should not be limited by these terms. These terms are only used to distinguish one element or parameter from another element or parameter. For example, the first slice image may be referred to as a second slice image, and similarly, the second slice image may be referred to as a first slice image, without departing from the scope of the various described embodiments. The first slice image and the second slice image are both describing one slice image, but they are not the same slice image unless the context clearly indicates otherwise. Similar situations also include a first three-dimensional model and a second three-dimensional model, or a first printing terminal and a second printing terminal.

Also, as used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context indicates otherwise. It will be further understood that the terms "comprises," "comprising," "includes" and/or "including," when used in this specification, specify the presence of stated features, steps, operations, elements, components, items, species, and/or groups, but do not preclude the presence, or addition of one or more other features, steps, operations, elements, components, species, and/or groups thereof. The terms "or" and/or "as used herein are to be construed as inclusive or meaning any one or any combination. Thus, "A, B or C" or "A, B and/or C" means "any of the following: a; b; c; a and B; a and C; b and C; A. b and C ". An exception to this definition will occur only when a combination of elements, functions, steps or operations are inherently mutually exclusive in some way.

In a scenario where a plurality of 3D printing devices (also referred to as printers, printing apparatuses, etc.) are required to print three-dimensional objects respectively, as described in the background art, for high-precision applications, the printed three-dimensional objects cannot be used or are poor in use feeling due to the small difference of the printing devices.

Taking the dental field in medical treatment tools as an example, when the dental objects manufactured by using 3D printing equipment, such as guide plates for dental parts, movable dentures, bridges, crowns, space retainers, tooth replacement devices, orthodontic attachments, orthodontic retainers, bases, piles, nail crowns, inlays, crown caps, veneers, implants, abutments, articulators, partial crowns, dentures, contact circles, nails, connectors, orthodontic brackets, etc., the dental objects need to be placed in the oral cavity of a patient or the dental objects need to be matched with each other, so that the requirements for the degree of attachment to the patient or the degree of combination with each other are high, and even if the printed dental objects have very small deviations, the use feeling of the patient is poor or even the printed dental objects cannot be used. The above description of the dental field is only an example, and the popularization of the dental field to other fields requiring high precision has low tolerance to small deviation.

In applications where there is only one printing device, some embodiments compensate for possible errors by the printing device by modifying the original three-dimensional model in the design software, and some embodiments ensure that the printed three-dimensional objects are the same size by adjusting the printing parameters of the printing device. However, these methods are not adaptable in the production background of a plurality of printing apparatuses. For example, in the example of modifying the original three-dimensional model on the design software, the user has high professional requirements, and the user is required to adaptively modify the original three-dimensional model according to the own characteristics of each printing device, so that the required workload is large and tedious; in the example of adjusting the printing parameters of the printing devices, the user is also required to adjust each printing device according to the specific hardware condition of each printing device, the attribute of the adopted curing material, and the like, and particularly when the accuracy required to be adjusted is high, the difficulty of the operation degree is also high; neither of these examples is applicable to application scenarios with multiple printing devices.

In view of this, the present application discloses a data processing method and a 3D printing method, which are applied to a printing system including a server system and a plurality of printing terminals. The data processing method is mainly executed by a server system configured with the data processing system, and the 3D printing method is mainly executed by a printing device configured with a printing terminal. And correspondingly adjusting the two-dimensional data of the three-dimensional model by the server system according to the correction data of each printing terminal, thereby generating a plurality of data to be printed respectively corresponding to each printing terminal and distributing the data to each printing terminal. By the method, the two-dimensional data can be adaptively modified on the printing system according to the respective characteristics of the printing terminals, so that the printing effect of each printing device provided with the printing terminals can achieve the same expectation, the complicated adjustment work is automatically completed on the server system, and the complicated adjustment work of the printing terminal by a user is not needed.

The memory controller may control access to the memory by other components of the device, such as the CPU and peripheral interfaces.

The at least one processing device is connected to the storage device and configured to execute and implement at least one embodiment of the data processing method described above when the at least one program is executed. The processing apparatus is, for example, a server, such as an application server or the like, that includes a processor operatively coupled to a memory and/or a non-volatile storage device. More specifically, the processor may execute instructions stored in the memory and/or the non-volatile storage device to perform operations in the computing device, such as generating image data and/or transmitting image data to an electronic display. As such, the processor may include one or more general purpose microprocessors, one or more special purpose processors, one or more field programmable logic arrays, or any combination thereof.

The interface device comprises at least one interface unit, and each interface unit is respectively used for outputting a visual interface, receiving a human-computer interaction event generated according to the operation of a technician and the like. For example, the interface devices include, but are not limited to: a serial interface such as an HDMI interface or a USB interface, or a parallel interface, etc.

Examples of the display device include a display, which may be a hardware device for displaying and generating input events in case of integrating a touch sensor. The display device can be in data connection with the processing device through an interface unit (such as an HDMI interface) in the interface device, or a network communication device (such as a WiFi module).

The input device is used for user operation, and signals generated based on the user operation can trigger the calling of some programs after being processed by the processing device so as to execute corresponding steps. Examples of the input device include a mouse, a keyboard, an input board, and the like.

The printing terminal is configured in the 3D printing device, and the 3D printing device is a printing device for manufacturing a three-dimensional object by using a light-cured material, and can be a DLP device, an SLA device, an LCD device or the like; it is also possible to use, for example, a fused deposition based FDM apparatus, or an SLS apparatus or SLM apparatus for a powder bed, etc. In the embodiment shown in fig. 1 below, a 3D printing apparatus based on the light-curing DLP technology is described as an example.

In a 3D printing apparatus based on the light-cured DLP technology, the energy radiation system includes a DMD chip, a controller, and a memory module, for example. Wherein the storage module stores therein a layered image layering the 3D component model. And the DMD chip irradiates the light source of each pixel on the corresponding layered image to the top surface of the container after receiving the control signal of the controller. In fact, the mirror is composed of hundreds of thousands or even millions of micromirrors, each micromirror represents a pixel, and the projected image is composed of these pixels. The DMD chip may be simply described as a semiconductor light switch and a micromirror plate corresponding to the pixel points, and the controller allows/prohibits the light reflected from each of the micromirrors by controlling each of the light switches in the DMD chip, thereby irradiating the corresponding layered image onto the photo-curable material through the transparent top of the container so that the photo-curable material corresponding to the shape of the image is cured to obtain the patterned cured layer.

Referring to fig. 1, a schematic structural diagram of a 3D printing apparatus according to an embodiment of the present disclosure is shown, where the printing apparatus includes acontainer 51, acomponent platform 52, a Z-axis driving mechanism 53, anenergy radiation system 54, and aprinting terminal 55.

Thecontainer 51 is for holding a light curable material. The capacity of the container depends on the type of the 3D printing device, and in general, the container capacity in the SLA-based printing device is larger than the container capacity in the DLP-based printing device because the printing format (or radiating format) of the SLA-based 3D printing device is larger than that of the DLP-based 3D printing device.

In certain embodiments, the light-curable material includes any liquid or powder material susceptible to light curing, examples of which include: a photocurable resin liquid, or a resin liquid doped with a mixed material such as an additive, a pigment, or a dye. Powder materials include, but are not limited to: ceramic powder, color additive powder, etc. The materials of the container include but are not limited to: glass, plastic, resin, etc. Wherein the volume of the container depends on the type of the 3D printing device. In some implementations, the container is often referred to as a resin vat.

Themember platform 52 is used to attach the irradiation-cured pattern cured layer so as to build up a three-dimensional object via the pattern cured layer. Specifically, the component platform is exemplified by a component plate. The component platform typically takes a preset printing reference surface located in the container as a starting position, and accumulates each solidified layer solidified on the printing reference surface layer by layer to obtain a corresponding 3D printed object.

The Z-axis driving mechanism 53 is connected to thecomponent platform 52 for controllably moving thecomponent platform 52 in the vertical axial direction to adjust the distance between thecomponent platform 52 and the printing reference surface and filling the photo-curable material to be cured. Wherein, the printing reference surface refers to the initial surface of the light-cured material irradiated. In order to accurately control the irradiation energy of each cured layer, the Z-axis driving mechanism needs to drive the component platform to move to a position where the minimum distance between the component platform and the printing reference surface is the layer thickness of the cured layer to be cured. In an embodiment where the 3D printing apparatus is an SLA apparatus with top surface laser scanning, the preset printing reference surface is generally located at a liquid level containing a resin liquid; in an embodiment where the 3D printing device is a bottom-exposed DLP device, the preset printing reference plane is typically located at the bottom of the container, or at a certain height from a preset position of the bottom, such as a DLP device using CLIP technology.

Theenergy radiation system 54 is used to irradiate the photocurable material in the container to obtain a patterned cured layer. Specifically, the energy radiation system irradiates the light-curing material in the container to obtain a three-dimensional object according to two-dimensional data in the data to be printed acquired based on theprinting terminal 55. In some implementation scenarios, the energy radiation system is also often referred to as an optical system or an optical machine, etc.

Theprinting terminal 55 is connected to theenergy radiation system 54 and the Z-axis driving mechanism 53, and is used for executing a 3D printing method to adhere and stack the patterned cured layer on thecomponent platform 52 to obtain a corresponding three-dimensional object. Theprinting terminal 55 is an electronic device including a processor, for example, theprinting terminal 55 is a computer device, an embedded device, or an integrated circuit integrated with a CPU.

Referring to fig. 2, a flowchart of a data processing method and a 3D printing method in an embodiment of the present application is shown, as shown in the figure, the data processing method may be executed by a server system in any of the foregoing embodiments, the data processing method includes step S110, step S120, and step S130, the 3D printing method may be executed by a printing terminal in any of the foregoing embodiments, and the 3D printing method includes step S210 and step S220. Specifically, the server system acquires correction data of a plurality of printing terminals corresponding to the three-dimensional model, then correspondingly adjusts two-dimensional data of the three-dimensional model based on the correction data of each printing terminal to generate data to be printed corresponding to each printing terminal, and then distributes the data to be printed corresponding to each printing terminal, and the printing device corresponding to each printing terminal prints the three-dimensional object based on the data to be printed, so that the three-dimensional objects printed by the plurality of printing devices can achieve the same expectation.

In step S210, each print terminal corresponding to the three-dimensional model transmits the correction data to the server system.

Wherein the three-dimensional model is the position and the shape of the three-dimensional object to be printed in the space described by the three-dimensional coordinate data. The three-dimensional coordinate data includes, for example, a start position of the three-dimensional model, and offset positions determined from describing a relative positional relationship between positions in the space of the three-dimensional model and the start position, or positioning positions determined from the offset positions and the start position. The starting position, the offset position, and the positioning position may be three-dimensional coordinate values described by a spatial coordinate system such as a rectangular three-dimensional coordinate system (or an angular coordinate system).

In order to optimize the file data volume of the three-dimensional model, the three-dimensional model is formed by splicing a plurality of basic units, wherein each three-dimensional coordinate data corresponds to the three-dimensional coordinate value of each basic unit in a corresponding three-dimensional coordinate system. The basic unit comprises a cubic unit used for filling a three-dimensional model space and a patch unit used for enclosing a three-dimensional model surface. Wherein each of the cubic units may be a cube of equal or unequal size (and/or shape). The patch elements may be two-dimensional planar structures of equal or unequal size (and/or shape). The shape is exemplified by basic geometric shapes such as triangle, quadrangle and the like, and the three-dimensional model is formed by splicing all basic units in a coplanar or common-edge mode.

It should be noted that, in some embodiments, the three-dimensional object corresponding to the three-dimensional model is suitable for a high-precision situation, for example, the three-dimensional model is a model of a tooth object, a printing device corresponding to the printing terminal prints the tooth object, and specific examples of the tooth object are described in the foregoing embodiments and are not described herein again.

Continuing to refer to step S210 shown in fig. 2, each printing terminal corresponding to the three-dimensional model transmits the respective correction data to the server system. And each printing terminal corresponding to the three-dimensional model means that the printing equipment corresponding to each printing terminal is respectively used for printing the three-dimensional model. In view of this, in some embodiments, the data processing method further includes step S100 (not shown), and in step S100, in one embodiment, the server system determines correspondence between the three-dimensional model and the plurality of printing terminals. The corresponding relation between the three-dimensional model and the plurality of printing terminals refers to the corresponding relation that the printing devices corresponding to the plurality of printing terminals are respectively used for printing the three-dimensional objects corresponding to the three-dimensional model. The three-dimensional model is acquired by a server system, and can be sourced from a local storage device of equipment, or from a cloud server of the Internet, or formed by user design, or uploaded by a user.

In one embodiment, the server system determines the correspondence between the three-dimensional model and the plurality of printing terminals based on a user operation. In other words, in the present embodiment, the server system determines, according to the user operation, a printing terminal corresponding to the three-dimensional model, which is to be used by a printing device corresponding to the printing terminal to print the three-dimensional model. The user operation refers to an operation of a user on an operation interface of a display device by using an input device, including but not limited to clicking (for example, clicking with an input device such as a mouse), dragging, releasing, and the like. The input device and the display device by which the user operates may be a part of the server system, or may be input devices and display devices connected to other electronic devices, and the other electronic devices transmit the user operation to the server system.

In other embodiments, the server system may also determine the correspondence between the three-dimensional model and the plurality of printing terminals based on pre-stored information. For example, the corresponding printing terminal is automatically determined for the three-dimensional model based on the sequence of obtaining the three-dimensional model, and for example, the printing terminal corresponding to the three-dimensional model is determined based on the correspondence stored inside.

For diversified printing requirements, in some embodiments, the three-dimensional model may be one or more. In an example where the three-dimensional model is one, the server system determines that there is a correspondence between the three-dimensional model and a plurality of printing terminals, that is, each of the printing devices corresponding to the plurality of printing terminals is to be used for printing the same three-dimensional object; in an example where the three-dimensional model is multiple, the server system determines a correspondence between each three-dimensional model and at least one printing terminal (e.g., one printing terminal for each three-dimensional model, or multiple printing terminals for each three-dimensional model), that is, each printing device corresponding to multiple printing terminals in the printing system may be assigned to print different three-dimensional objects, or may print different three-dimensional objects partially.

The correction data refers to correction parameters of the corresponding curing materials, which are set to enable at least one of the color, the shape and the size of the three-dimensional object printed by the printing device corresponding to each printing terminal to meet the same expected precision, that is, the correction data has a corresponding relationship with the printing terminal and the curing materials adopted in the 3D printing device corresponding to the printing terminal.

In an embodiment, the correction data comprises at least one of image correction data and process correction data.

The image modification data is used for describing modification information related to the image, and the image modification data may include any parameter of an image scaling parameter, an image bias parameter, an image contour compensation parameter, an image gray value adjustment parameter, and the like.

Specifically, the image scaling parameter may include an x-direction scaling parameter and a y-direction scaling parameter, which are used to represent scaling down or up the slice image, based on the direction of image scaling.

The image offset parameter is used to represent an adjustment parameter for the degree of gap between two image contours having an assembly relationship in a slice image, such as an image contour of a hole structure for setting the hole structure and an image contour of an axial structure. Referring to fig. 3, which is a schematic illustration of image offset parameters according to an embodiment of the present application, a holestructure image outline 10 having an assembly relationship in a slice image and a shaftstructure image outline 20 are shown, after printing of a three-dimensional object is completed, a shaft structure can be disposed in the hole structure, and the image offset parameters are shown as a gap between the shaftstructure image outline 20 and the holestructure image outline 10 when the shaftstructure image outline 20 is disposed according to the assembly relationship.

In one embodiment, the image bias parameter may be a fixed value, and the adjustment of each slice image is adjusted according to the fixed value. In other embodiments, to further improve the accuracy of the printed three-dimensional object, the image bias parameter is associated with the image profile size, e.g., the image bias parameter is a function of the image profile size, and the adjustment of the slice image varies according to the image profile size.

The image contour compensation parameter is used to represent an adjustment parameter of a gap between two adjacent but unassembled image contours in a slice image, please refer to fig. 4, which is a schematic illustration of the image contour compensation parameter in an embodiment of the present application, and is illustrated as an image contour corresponding to two axis structures in the slice image, where the first axisstructure image contour 25 and the second axisstructure image contour 26 are image contours corresponding to two adjacent axis structures, and the image contour compensation parameter is an adjustment parameter representing a gap (as denoted by Δ in the figure) between the first axisstructure image contour 25 and the second axisstructure image contour 26.

The process correction data included in the correction parameter is used to represent modification information related to a printing process in 3D printing, and the process correction data may include, for example, an energy adjustment parameter used to represent a parameter of energy adjustment for the energy radiation system, such as an exposure duration or an exposure power adjustment parameter. In some embodiments, the energy adjustment parameter may be a fixed value, and the adjustment of each slice image is adjusted according to the fixed value. In other embodiments, in order to ensure the reliability of the printing process, the energy adjustment parameter is associated with a slice position, for example, the slice position associated with the energy adjustment parameter is the number of layers of the slice image during the printing process, and the adjustment of the process data of the slice image is different according to the number of layers of the slice image.

In some application scenarios, the printing terminal may also perform auxiliary printing operations such as print monitoring and generation support during the process of executing the print job, and therefore, in some embodiments, the correction data may further include function requirement data, where the function requirement data is used to indicate requirement information corresponding to an auxiliary printing function executed by the printing terminal, for example, when the printing terminal performs defective product detection during the process of executing the print job, the function requirement data is, for example, a command for generating a connected region, and the connected region may be used as reference information for defective product detection during the printing process of the printing terminal. For another example, the printing terminal needs to support an area with insufficient stress during the process of executing the printing operation, the functional requirement data is, for example, a lower surface identification instruction, and the printing terminal can generate support for the corresponding area in the slice according to the identification information during printing.

It should be noted that the content of the correction data described in the above embodiments is only an example, and those skilled in the art may also make adjustments or rearrangements according to the needs, and the present application does not limit this.

As mentioned above, the correction data has a corresponding relationship with the printing terminal and the curing material used in the 3D printing apparatus corresponding to the printing terminal, and therefore, in some embodiments, the printing terminal prestores a correction data list including the correction data corresponding to each curing material.

In some embodiments, the correction data transmitted by each printing terminal is determined based on a user operation. For example, the user operates to select which of the cured materials corresponds to the correction parameter. For another example, the user operates to select the function requirement data included in the correction parameter. The user operation refers to an operation of a user on an operation interface of the display device by using an input device, and includes but is not limited to clicking (for example, clicking with an input device such as a mouse), dragging, releasing, and the like. The input device and the display device by which the user operates can be a part of the printing terminal, or can be input devices and display devices connected by other electronic devices, and the other electronic devices transmit the user operation to the printing terminal. In view of this, in an embodiment, the printing method further includes: the printing terminal displays a selection interface of the correction data on the printing terminal based on a user operation.

The user can Save the selected correction data by operating the virtual key marked as "Save" to prepare for the server system to acquire the correction data, and can Cancel the change or selection of the correction data by operating the virtual key marked as "Cancel". It should be noted that fig. 5 is only an exemplary illustration, and in practical applications, a person skilled in the art may add or delete parameters based on actual needs, and the application is not limited thereto.

With continued reference to fig. 2, in step S110, the server system acquires correction data of a plurality of printing terminals corresponding to the three-dimensional model. The correction data may be, for example, sent to the server system by the printing terminal in the manner of step S210 in any of the foregoing embodiments, and the content included in the correction data may refer to that shown in any of the foregoing embodiments, which is not described herein again.

In step S120, the server system adjusts the two-dimensional data of the three-dimensional model based on the correction data of each printing terminal to generate data to be printed corresponding to each printing terminal.

The two-dimensional data is information obtained by discretizing a three-dimensional model into a series of two-dimensional layers (also referred to as layering processing or slicing processing) and adding process parameters. In an embodiment, the two-dimensional data comprises slice image data and process data.

The slice image data is used to describe slice images (also referred to as cross-sectional images) of each layer, and includes information such as image contour and filling path. The image contour is a contour for illustrating a corresponding independent structure in the slice image, e.g., the image contour of an axial structure is a circle. In some embodiments, a slice of the image may have multiple image contours within it. The filling paths are parallel lines or grid lines formed based on image outlines, the parallel lines or grid lines are distributed in an area needing to be printed, and the image outlines and the coordinate data of the filling paths form a slice image together.

The process data is a print process for correspondingly describing the slice image of each layer, and includes, for example, an energy parameter indicating energy information set for the energy radiation system to print the layer, such as an exposure time period or an exposure power. It should be noted that, the two-dimensional data, the slice image data, and the process data are included by way of example only, and in other embodiments, the two-dimensional data may also include one of the slice image data or the process data, the slice image data may also include other information for describing the slice image, such as a gray-level value of the slice image, and the process data may also include other information related to the printing process, such as a moving speed of the energy radiation system, which is not limited in this application.

In one embodiment, the step of the server system adjusting the two-dimensional data of the three-dimensional model based on the correction data of each printing terminal includes: at least one of the information of the gradation value, the shape, and the size of the slice image in the two-dimensional data is adjusted based on the image correction data in the correction data. The server system adjusts the size information of the slice images according to the acquired image correction data, wherein the adjusting of the size information of the slice images can comprise adjusting the magnification or reduction ratio of each layer of slice images, can also comprise adjusting the deviation degree between two image outlines with an assembly relation, and can also comprise adjusting the distance between two adjacent image outlines without the assembly relation.

In an embodiment, the image modification data includes an image scaling parameter, the adjusting the size information of the slice image includes adjusting the enlargement or reduction ratio of each slice image according to the scaling parameter, and the server system enlarges or reduces the image outline of each slice image in an equal ratio according to the scaling parameter.

In another embodiment, the image correction data includes image offset parameters, and the adjusting the size information of the slice image includes adjusting a size of a gap between two image contours in an assembled relationship. In an example, the offset parameter is a fixed value, and the server system adjusts the gap between the two image contours having the fitting relationship by adjusting the contour of one of the image contours corresponding to the fitting portion so that the gap therebetween is the fixed value, but of course, the server system may also adjust the contour of each of the two image contours corresponding to the fitting portion so that the gap therebetween is the fixed value. As will be described in detail with reference to fig. 6, fig. 6 is a schematic diagram showing a server system adjusting size information of a slice image according to an embodiment of the present application, in which the server system adjusts a holestructure image outline 10 having an assembly relationship in the slice image and an axisstructure image outline 20, for example, an image offset parameter is d0, the server system increases a gap between theimage outline 100 and the image outline 101 to d0 according to the image offset parameter, and the server system can adjust the holestructure image outline 10 by expanding anoutline 100 of a corresponding assembly portion outward by d0 (as indicated by a dotted arrow in the figure), so that when the adjusted hole structure image outline 10' is configured with the axisstructure image outline 20, the gap between the two is d 0. Of course, the adjustment can also be made by shrinking the axialstructure image contour 20 inward by d0, which is not shown in the figure.

In order to further improve the accuracy of the printed three-dimensional object, in some other examples, the image correction data includes an image bias parameter associated with an image profile size (e.g., the image bias parameter is a function of the image profile size), and the server system adjusts the deviation between at least two image profiles according to the image profile size, wherein the image profile size mainly refers to the size of the assembly joint portion of the two. For example, the bias parameter is a positive correlation function related to the size of the image contour, and the larger the size of the image contour is, the larger the adjustment degree of the deviation between the image contours by the server is. Fig. 7 is a schematic diagram showing an embodiment of the present application in which a server system adjusts size information of a slice image, which is a functional relationship between an image Offset parameter and an image contour size (where an abscissa r represents an image contour size and an ordinate Offset represents an image Offset parameter), a holestructure image contour 11 and an axisstructure image contour 21 having an assembly relation and an aperture r1 in the slice image, a holestructure image contour 12 and an axisstructure image contour 22 having an assembly relation and an aperture r2 in the slice image, and in gap adjustment of the two pairs of image contours with different sizes, the server system adjusts thecontour 110 of a corresponding assembly portion in the holestructure image contour 11 to be expanded outward by d1 (as indicated by a dotted arrow in fig. 7) according to a corresponding relationship between the image Offset parameter and the image contour size to obtain an adjusted hole structure image contour 11', the holepattern image profile 12 is adjusted in such a way that theprofile 120 of the corresponding fitting portion in the holepattern image profile 12 is expanded outward by d2 (as indicated by the dashed arrow in fig. 7) to obtain an adjusted hole pattern image profile 12'. Of course, the axialstructure image contour 21 may be adjusted by being inwardly contracted by d1 and the beamstructure image contour 22 may be inwardly contracted by d2, which is not shown in the figure.

In another embodiment, the image correction data includes image contour compensation parameters, the adjusting the size information of the slice image includes adjusting a gap between two adjacent but unassembled image contours, and the server system adjusts the gap between the two image contours by adjusting a shape of a portion of one of the image contours that is close to the other image contour or adjusting shapes of adjacent portions of the two image contours, respectively. Fig. 8 is a schematic diagram illustrating that the server system adjusts the size information of the slice image according to an embodiment of the present application, where the slice image has a third axis structure image contour 23 and a fourth axis structure image contour 24, and the server system adjusts the gap between the two image contours by modifying the shape of the third axis structure image contour 23 on the side close to the fourth axis structure image contour 24 to obtain an adjusted third axis structure image contour 23', so as to increase the gap between the two image contours. Fig. 8 is only an example, and in other embodiments, the shape of the fourth axis structure image contour 24 near the third axis structure image contour 23 may also be adjusted, which is not limited in this application.

It should be noted that the size information of the adjustment slice image described in the above embodiments is only an exemplary description, and in other embodiments, the server system may perform corresponding adjustment operations according to the content of the image correction data.

As previously mentioned, the correction data may also include process correction data, and in view of this, in some embodiments, the step of adjusting the two-dimensional model of the three-dimensional model based on the correction data of each printing terminal accordingly includes: adjusting process data in the two-dimensional data based on process correction data.

In some embodiments, the process correction data includes an energy adjustment parameter, such as an exposure duration adjustment parameter, and the server system modifies the exposure duration in the process data according to the adjustment parameter. In some examples, the exposure duration adjustment parameter included in the process correction data is associated with the slice position in consideration of reliability during printing, so that the server system adjusts the exposure duration of each slice image according to the slice image data and the process correction data. For example, the slice position is the number of layers of the slice during printing, and the exposure is performedThe duration adjustment parameter includes an adjustment parameter n1 corresponding to the first layer (e.g., "1" in FIG. 5)^st Layer(s) "), and the adjustment parameter n2 corresponding to the second layer (e.g.," 2 "in FIG. 5)^nd Layer(s), and adjusting parameter n3 corresponding to the third layer (e.g., "3" in FIG. 5)^rd Layer(s), the server system corresponds the corresponding process data of the section image data of the corresponding layer in the adjustment two-dimensional data respectively according to the adjustment parameter of these three layers, when the adjustment parameter n1 of first layer is great, the server system can be with the exposure duration adjustment that first layer section image data corresponds great, then when printing terminal carries out the first layer and prints, can make first printing layer and component platform laminating more inseparable to can prevent that the problem that the piece appears falling in the object is printed. Of course, the above is only an example, and those skilled in the art can adjust the process data corresponding to the slice image data according to the specific meaning of the slice position and the specific relationship with the exposure duration adjustment parameter.

As described above, in some embodiments, the correction data may further include function requirement data, and the step of adjusting the two-dimensional data of the three-dimensional model based on the correction data of each printing terminal includes: and generating corresponding function support data based on the function requirement data. For example, the print terminal performs a defective detection during execution of a print job, the function requirement data is, for example, a generation connected region instruction, and the server system generates projection image information of the three-dimensional model as function support data according to the generation connected region instruction. For another example, the printing terminal needs to support an area with insufficient stress during the process of executing the printing job, and the functional requirement data is, for example, a lower surface identification instruction, and the server system marks the area with insufficient stress in the slice image according to the lower surface identification instruction to serve as functional support data.

As described above, in step S120, the server system adjusts the two-dimensional data of the three-dimensional model accordingly based on the correction data of each printing terminal, and generates data to be printed corresponding to each printing terminal. That is, the server system adjusts the two-dimensional data of the corresponding three-dimensional model according to the corresponding relationship between the three-dimensional model and the printing terminals and according to the correction data of each printing terminal in the manner described in any of the above embodiments. For example, the server system obtains a three-dimensional model, and the three-dimensional model respectively corresponds to the first printing terminal and the second printing terminal, that is, the first printing terminal and the second printing terminal are both used for printing a three-dimensional object corresponding to the three-dimensional model, the server system modifies the two-dimensional data of the three-dimensional model based on the correction data of the first printing terminal to generate data to be printed of the first printing terminal, and modifies the two-dimensional data of the three-dimensional model based on the correction data of the second printing terminal to generate data to be printed of the second printing terminal. For another example, if the server system obtains two three-dimensional models, namely a first three-dimensional model and a second three-dimensional model, and the first three-dimensional model corresponds to the first printing terminal, and the second three-dimensional model corresponds to the second printing terminal, that is, the first printing terminal is used for printing the three-dimensional object corresponding to the first three-dimensional model, and the second printing terminal is used for printing the three-dimensional object corresponding to the second three-dimensional model, the server system modifies the second dimension of the first three-dimensional model based on the correction data of the first printing terminal to generate the data to be printed of the first printing terminal, and modifies the second dimension of the second three-dimensional model based on the correction data of the second printing terminal to generate the data to be printed of the second printing terminal. It should be noted that the above numbers and corresponding relations are only exemplary illustrations, wherein the corresponding relation between the three-dimensional model and the printing terminals and the number of the printing terminals may also be adjusted according to practical applications, and the application is not limited thereto.

The document to be printed refers to code information that can be recognized by the printing terminal and is generated based on the adjusted two-dimensional data (such as including slice image data, process data, and function support data), and the document to be printed is a GCode document, for example. In some embodiments, the data to be printed further includes identification information of its corresponding printing terminal, for example, a unique identification such as an address and a number of the printing terminal, so that the data to be printed can be allocated to its corresponding printing terminal.

In some embodiments, the data to be printed includes identification information of a corresponding printing terminal, and the server system allocates each data to be printed to its corresponding printing terminal based on the identification information.

The data to be printed is the modification of the server system to the two-dimensional data of the three-dimensional model based on the correction data of each printing terminal, and the correction data refers to the correction parameters of the corresponding curing material, which are set for enabling at least one of the color, the shape and the size of the three-dimensional object printed by the printing equipment corresponding to each printing terminal to meet the same expected precision. Therefore, after each printing terminal controls the printing device to perform the printing operation based on the respective data to be printed, the obtained three-dimensional object can achieve the same expectation. The same expectation may be achieved for the three-dimensional object as a whole, or for a portion of the three-dimensional object having a specific structure or a specific shape.

In an embodiment, the same expectation refers to a preset printing precision threshold, and the three-dimensional objects printed by the printing terminals all satisfy the printing precision threshold. Taking the printed three-dimensional object as a tooth object as an example, the preset printing precision is any value between 10 μm and 20 μm, and may be set to 10 μm, 15 μm, or 20 μm, for example.

The hardware device refers to a hardware device corresponding to the server system.

Theprocessing module 301 is configured to correspondingly adjust the two-dimensional data of the three-dimensional model based on the correction data of each printing terminal, so as to generate a plurality of data to be printed corresponding to each printing terminal. The process of theprocessing module 301 instructing the hardware device to perform the corresponding operation corresponds to step S120 in the foregoing embodiments, and is not described in detail here.

Thedisplay module 302 is configured to allocate the data to be printed to each printing terminal, so that the three-dimensional models printed by each printing terminal based on the data to be printed achieve the same expectation.
