Problems solved by technology

[0003] Stereo-curing 3D printing needs to use solid materials and support materials to form finished products. It is very important to choose appropriate molding materials. At present, only 3D Systems and OBJET have photo-curing 3D printing equipment and supporting molding materials. At present, there are no related products in China. The preparation of materials is an urgent problem that needs to be solved

Abstract

The invention relates to a 3D printing material, which is solidified after being injected in a 3D printing machine, and the printing material comprises a curable urethane acrylate prepolymer, a photoinitiator and a sulfur-containing surfactant. The material provided in the invention can be taken as a three dimensional printer moulding material, and can be used for a plurality of three dimensional printers with different models.

Description

technical field [0001] The invention relates to a 3D printing material, belonging to the field of rapid prototyping materials, more specifically, a solid material and a supporting material for a three-dimensional rapid printer. Background technique [0002] Stereo-curing 3D printing is similar to uv inkjet printing, which is a rapid prototyping technology using liquid jet molding. During the molding process, two sets of nozzles are used to spray the solid material and the support material respectively, and they are cured by ultraviolet light. They are piled up and formed layer by layer. After printing, the support material is removed by water or hot melt to obtain the desired finished product. [0003] Stereo-curing 3D printing needs to use solid materials and support materials to form finished products. It is very important to choose appropriate molding materials. At present, only 3D Systems and OBJET have photo-curing 3D printing equipment and supporting molding materials....
