High-precision double-forming-mode 3D printer and forming method thereof

Abstract

The invention discloses a high-precision double-forming-mode 3D printer and a forming method thereof. The high-precision double-forming-mode 3D printer comprises a frame support structure, a plane mechanical motion structure, a piezoelectric micro nozzle structure and a powder forming bin which is inlaid in the upper surface of the frame support structure. A detachable gluing forming bin is arranged in the powder forming bin. A powder forming platform, a gluing forming platform and a vertical mechanical motion structure are arranged on the lower portion correspondingly, and the vertical mechanical motion structure drives the platforms to move. The plane mechanical motion structure, the piezoelectric micro nozzle structure and the vertical mechanical motion structure are connected to mastercontrol circuit control unit. According to the high-precision double-forming-mode 3D printer and the forming method thereof, the gluing forming bin is selectively installed in the powder forming bin,so that forming printing of different types of forming materials can be achieved; and through the piezoelectric glass combined micro nozzle structure, controllability of printing ink quantity can beimproved significantly, and the high-precision double-forming-mode 3D printer is particularly suitable for powder bonding of single-nozzle large ink quantity or gluing reflecting 3D printing forming.

Description

technical field [0001] The invention belongs to the field of digital micro-jet three-dimensional printer production, in particular to a high-precision three-dimensional printer and a forming method thereof with two processes of 3DP powder forming and spray glue forming.

Digital micro-jet 3D printing technology is a technology that uses micro-jet technology to directly spray molding or micro-jet binder to powder bed bonding molding, and layer-by-layer production technology. Digital micro-injection technology plays an extremely important role in 3D printing technology, and ...

AI Technical Summary

Problems solved by technology

Among them, the method of binder jetting to powder bed printing is favored by scientific research institutes and companies in the field of biomaterials research and development, but the existing problem is that the jet nozzle is refitted from a commercial inkjet printer, which is easy to clog and the inkjet volume is too small (less than 10 picoliters), higher cost

Extrusion printing is widely used, but it requires contact molding, and the resolution is about 1 mm, so it is difficult to apply to finer occasions, such as 3D printing of vascular tissue
