Abstract

The invention relates to a method and device for ceramic denture 3D printing suitable for light curing molding and belongs to the technical field of tooth making. According to the method, through scanned tooth data and data processing, data of each layer of image after a data model to be printed is sliced are obtained and transmitted to a control system, a liquid supplementing action is controlled through the control system so that the liquid level of a base material can be always kept at the preset height, the base material is configured by photosensitive resin and ceramic powder according to the ratio, and the control system controls completion of stirring of supplemented liquid after liquid supplementing; and a bottom projection manner is adopted for printing, slice images of each layer of image are projected successively, light source exposure is conducted, and curing is completed layer by layer. The method and device have the beneficial effects that the making process is simple, the making efficiency is high, the consumption of materials is low, the making precision is high, and the match is good.

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...
