Problems solved by technology

[0002] At present, gradient non-metallic material products are mainly manufactured by layer-by-layer pressing, but when the interface between layers is a complex surface, such as imitating the multi-layer complex surface structure of natural teeth, this method is complicated and cumbersome, and its Simple interface structure and single material distribution control cannot meet the needs of clinical precision bionic manufacturing
3D inkjet printing technology provides new possibilities for the manufacture of complex gradient biomimetic materials, but there is a lack of supporting material technology

Abstract

The invention relates to a photocuring 3D printing material and a preparation method thereof. The preparation method comprises the following steps: 1) adding 50-90 parts of PMMA and 10-50 parts of nano-hydroxyapatite or nano-zirconia or nano-glass fibers or nano-carbon fibers in a container, and blending to form a mixed liquid; 2) adding a coloring agent with a proper concentration into the mixedliquid obtained in the step 1); and 3) printing by using an ink-jet printer to form a high polymer material product for a human body or an animal body. According to the invention, the requirements forintegrated printing of high polymer material products with different abrasion degrees, different colors and different bending strengths can be met.

Description

technical field [0001] The invention relates to photocurable 3D printing materials, in particular to a photocurable 3D printing material and a preparation method thereof. Background technique [0002] At present, gradient non-metallic material products are mainly manufactured by layer-by-layer pressing, but when the interface between layers is a complex surface, such as imitating the multi-layer complex surface structure of natural teeth, this method is complicated and cumbersome, and its A simple interface structure and a single material distribution control cannot meet the needs of clinical precision bionic manufacturing. Three-dimensional inkjet printing technology provides a new possibility for the manufacture of complex gradient biomimetic materials, but there is a lack of supporting material technology. Contents of the invention [0003] In order to overcome the above shortcomings, the patent of the present invention provides a photocurable 3D printing material and ...
