3D printer using ceramic as raw material

Abstract

The invention discloses a 3D printer using ceramic as a raw material. The 3D printer using the ceramic as the raw material comprises a laser head assembly, an exhaust assembly and a forming platform assembly. The laser head assembly comprises a laser, a light path adjusting combined mirror, an XY scanning galvanometer and a focusing lens. The forming platform assembly comprises a forming platform and a material laying mechanism. The material laying mechanism comprises a material laying hopper and a cylinder. A light ruler is installed on one side of the forming platform assembly, a lifting lead screw pair is installed on the other side of the forming platform assembly, a lifting motor is installed at the bottoms of lifting lead screws in the lifting lead screw pair, an upper limiting block is arranged on the tops of the lifting lead screws in the lifting lead screw pair, and a lower limiting block is arranged at the bottoms of the lifting lead screws in the lifting lead screw pair. The exhaust assembly comprises an exhaust hood and an exhaust pipe connected to the exhaust hood, wherein an exhaust fan is connected to the exhaust pipe, and a purifier is connected to the end of the exhaust pipe. According to the 3D printer using the ceramic as the raw material, the light path of the laser is easy to control, pollution caused by harmful gas emission to the environment is avoided, the forming platform is high in movement accuracy, and the 3D printing effect is good.

Description

technical field [0001] The invention relates to the technical field of 3D printers, in particular to a 3D printer using ceramics as raw materials. Background technique [0002] There are many molding materials for 3D printers, and the molding principles are different according to the different molding materials. Ceramics, as one of them, have many prototypes put into use. The basic principles include the laying mechanism and laser components. The laser components are formed by ablation layer by layer; the existing 3D printers using ceramics as raw materials have some shortcomings in the detail design. Specifically, the optical path design of the laser is unreasonable and there is no exhaust mechanism, which makes the operating environment of the operator relatively difficult. Bad, at the same time, the lifting movement of the forming platform is unreliable. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is to provide a 3D pri...
