Abstract

The invention relates to a method and device for 3D printing ceramic dentures suitable for light-curing molding, which belong to the technical field of tooth production. In the method, tooth data obtained by scanning are processed to obtain images of each layer after slicing the data model to be printed. The data is sent to the control system, and the control system controls the liquid level to maintain the liquid level of the base material at the preset height. The base material is configured in proportion to the photosensitive resin and ceramic powder. After the liquid replenishment, the control system controls the filling liquid. After the mixing is completed, the bottom projection method is used for printing, and the sliced ​​graphics of each layer of the image are projected one by one, and the light source is exposed to complete the curing layer by layer. The invention has the advantages of simple production process, high production efficiency, less consumables, high production precision and good matching.

Description

technical field [0001] The invention relates to the technical field of denture production, in particular to a method and device for 3D printing ceramic dentures suitable for light-curing molding. Background technique [0002] Currently common 3D printing technologies include: Stereolithography (SL for short), Selective Laser Sintering (SLS), Selective Laser Melting (SLM), Fused Deposition Modeling (Fused Deposition Modeling, FDM), three-dimensional printing (Three Dimensional Printing, 3DP), etc. Stereolithography (SL) and 3D printing technology based on DLP (Digital Light Processing) stereolithography projection are both stereolithography technologies. [0003] The stereolithography molding method (including laser photocuring and DLP photocuring, collectively referred to as photocuring) has the following advantages: (1) high dimensional accuracy, and the tolerance range is within ±0.03mm~±0.1mm; (2) excellent surface Compared with other 3D molding technologies such as FDM...
