技术领域technical field
本实用新型涉及3D打印领域，尤其涉及一种应用于口腔修复场合的LCD光固化3D打印机。The utility model relates to the field of 3D printing, in particular to an LCD light-curing 3D printer applied to the occasion of oral restoration.
背景技术Background technique
3D打印技术属于快速成型技术的一种，它是一种以数字模型文件为基础，运用粉末状金属或塑料等可粘合材料，通过逐层堆叠累积的方式来构造物体的技术。3D printing technology belongs to a kind of rapid prototyping technology. It is a technology based on digital model files, using bondable materials such as powdered metal or plastic, and constructing objects by stacking and accumulating layer by layer.
现有的3D打印技术可分为光固化成型(SLA)、选择性激光烧结(SLS)、熔融沉积快速成型(FDM)及数字光处理(DLP)。The existing 3D printing technologies can be divided into Stereolithography (SLA), Selective Laser Sintering (SLS), Fused Deposition Rapid Prototyping (FDM) and Digital Light Processing (DLP).
其中，对于现有的SLA光固化成型技术来说，其实现方式为：用特定波长与强度的激光聚焦到光固化材料表面，使之由点到线，由线到面顺序凝固，完成一个层面的绘图作业，然后升降台在竖直方向移动一个层片的高度，再固化另一个层面，这样层层叠加构成三维实体。Among them, for the existing SLA light-curing molding technology, the implementation method is: use a laser with a specific wavelength and intensity to focus on the surface of the light-curing material, so that it is sequentially solidified from point to line and from line to surface to complete a layer. Then the lifting platform moves the height of one layer in the vertical direction, and then solidifies another layer, so that the layers are superimposed to form a three-dimensional entity.
但是，由于SLA光固化成型技术是点-线-面，这样技术在成型方式原理上极大地限制了成型方式，故成型效率低；同时，SLA光固化打印机采用紫外激光器结合振镜式扫描，二者价格都是比较昂贵，一台SLA光固化打印机少则上万，多则几十万；再者，由于SLA技术是点成型技术，软件切片时需要把整个模型转换成点数据，数据处理软件运算量大，添加支撑对经验要求也高。However, since the SLA photo-curing molding technology is point-line-surface, this technology greatly limits the molding method in principle, so the molding efficiency is low; at the same time, the SLA photo-curing printer uses a UV Both of them are relatively expensive, and an SLA light-curing printer can range from tens of thousands to hundreds of thousands; moreover, since SLA technology is a point forming technology, the entire model needs to be converted into point data when the software slices, and the data processing software The amount of calculation is large, and adding support requires high experience.
因此，急需要一种LCD光固化3D打印机来克服上述的缺陷。Therefore, there is an urgent need for a LCD light-curing 3D printer to overcome the above-mentioned defects.
