摘要：
A 3D printing material and equipment for three-dimensional laser deposition molding are provided. The present disclosure relates to the field of 3D printing. The problem that existing equipment is incapable of meeting fast printing speed, high printing accuracy, large product printing and simple printing equipment, and is difficult in modeling of a printing model is solved. An inorganic filler and a polymer are mixed to prepare a printing viscous liquid with proper viscosity, then the inorganic filler printing viscous liquid is extruded out of a print head through extrusion equipment, and the viscous liquid is subjected to stereolithography through high-intensity laser in the printing process. The 3D printing technology provided by the present disclosure, which integrates the advantages of stereo lithography appearance and fused deposition modeling, is innovated based on the stereo lithography and the fused deposition modeling, and is an innovative 3D printing technology.
