Abstract

A method and apparatus applicable in a 3D printed ceramic denture formed by stereolighography, related to the technical field of denture fabrication. In the method, dental data acquired by scanning is data processed to produce data of each sliced layer of image of a data model to be printed and transmitted to a control system, a liquid replenishment action is controlled by a control system so that the liquid level of a base material is always kept at a preset height, the base material is prepared proportionally from a photosensitive resin and a ceramic powder, when the liquid is replenished, the control system controls the mixing of the replenished liquid, printing is done by employing a scheme of bottom projection, sliced pattern of each layer of image are projected sequentially, and exposure to a light source is performed to complete curing layer by layer.

Description

technical field [0001] This application relates to the technical field of denture production, in particular to a method and device for 3D printing ceramic dentures suitable for photocuring 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 F...
