本发明涉及一种3D打印装置及工艺,尤其是涉及一种可用于成型大型制品的3D打印装置及工艺。The invention relates to a 3D printing device and process, in particular to a 3D printing device and process that can be used to form large-scale products.
背景技术Background technique
快速成型技术(又称为快速原型制造技术，Rapid Prototyping Manufacturi-ng，简称RPM)，又被称作3D打印。该技术根据物体的三维模型数据，通过成型设备以逐层叠加的方式制造实体。该技术能克服目前传统机械加工无法实现的特殊结构障碍，可以实现任意复杂结构部件的简单化生产。现有的3D打印技术主要分为，熔融沉积成型(FDM)、光固化立体印刷(SLA)、选择性激光烧结(SLS)、立体平板印刷(SLA)、三维喷印(3DP)和数字光处理(DLP)等等。Rapid prototyping technology (also known as rapid prototyping manufacturing technology, Rapid Prototyping Manufacturi-ng, referred to as RPM), also known as 3D printing. This technology manufactures entities in a layer-by-layer manner through molding equipment based on the three-dimensional model data of the object. This technology can overcome the special structural obstacles that cannot be realized by traditional mechanical processing at present, and can realize the simplified production of arbitrary complex structural parts. The existing 3D printing technologies are mainly divided into fused deposition modeling (FDM), stereolithography (SLA), selective laser sintering (SLS), stereolithography (SLA), three-dimensional jet printing (3DP) and digital light processing. (DLP) and so on.
目前的熔融沉积成型(FDM)技术主要是螺杆塑化并输送熔体通过三维运动机构在平板上逐层堆积成型，或通过加热喷嘴熔融丝料以同样的原理在底板上逐层堆积成型。螺杆塑化输送式打印机的缺点是打印物料的工艺参数难以调试精确，并且螺杆加热段温度的波动及机筒内流料量的不均匀性都会直接影响打印制品的精度。加热喷嘴熔丝式的3D打印机虽然在一定程度上可以保证打印精度，但打印材料只能是丝料并且体型和功率都很小，所以存在打印材料种类受限制、打印速度过慢以及不能成型大型制品的缺点。The current Fused Deposition Modeling (FDM) technology is mainly to plasticize the screw and transport the melt to form layer by layer on the flat plate through a three-dimensional motion mechanism, or to melt the silk material through the heating nozzle to form layer by layer on the bottom plate by the same principle. The disadvantage of the screw plasticizing conveying printer is that the process parameters of the printed material are difficult to adjust accurately, and the temperature fluctuation of the screw heating section and the unevenness of the flow rate in the barrel will directly affect the accuracy of the printed product. Although the heating nozzle fused filament 3D printer can guarantee the printing accuracy to a certain extent, the printing material can only be filament and the size and power are very small, so there are restrictions on the types of printing materials, the printing speed is too slow, and it cannot form large-scale 3D printers. product shortcomings.

The opposite movement and the left and right movement of the laying roller make the pellets evenly spread on the top of the molding cavity, and then the injection system is driven by the X-direction movement mechanism and the Y-direction movement mechanism on the top of the pellet layer according to the three-dimensional digital model in the data storage Spray glue to the granule layer to bond part of the granules to realize the bonding of the granules in the cross-sectional profile and the formed part below. When the bonding of a layer of cross-section is completed, the Z-direction movement mechanism drives the storage chamber. The piston moves up the thickness of one layer, and at the same time, the piston of the forming chamber moves down by one layer of thickness, and the laying roller spreads a layer of pellets on it to bond a new layer of cross-section until the entire model printing process is completed; the second In the first step, the printed product is taken out after the glue is cured, and the laying roller pushes the excess pellets into the recycling cavity, and the outer surface of the printed product is coated with a layer of coating with a higher melting point than the pellets and a certain degree of elasticity. layer, and then put it into the heating chamber of the microwave heater for heat treatment. Since the melting point of the coating layer is higher than that of the pellets, when the pellets melt, the coating layer is still in a solid state, which can form a solid state for the molten material. A certain wrapping effect avoids the collapse of the product when heated; due to the certain thermoplasticity of the coating layer, it can allow the molten material to have a certain elastic expansion, thereby avoiding the generation of internal stress. Different materials need to be heated at different temperatures, which can be adjusted by adjusting The temperature on the thermostat is controlled; the third step is to cool the product after internal heating and melting. After cooling, the coating layer is removed and the surface is treated to obtain the final product.

The granular materials can be elastic balls, and glue is filled between the elastic balls to bond the elastic balls together. Some fillers sensitive to microwaves are added to the glue. During the heating process, the heat source is located in the glue, and the heat transfer through the glue makes the outer layers of the contacting elastic balls melt and bond together.
