Abstract

A three-dimensional printing apparatus having electrostatic auxiliary is disclosed. The apparatus includes a printing platform, a feeding device, a nozzle, and a high voltage power supply. The feeding device and the nozzle are disposed above the printing platform. The nozzle is connected to the feeding device and is located between the feeding device and the printing platform. A distance between the nozzle and the printing platform is less than or equal to 1 cm. The high voltage power supply has an output end electrically connected to the nozzle and a ground end electrically connected to the printing platform.

Description

technical field [0001] The invention relates to a three-dimensional printing technology, and in particular to an electrostatic-assisted three-dimensional printing device. Background technique [0002] Regenerative medicine can be roughly divided into four major fields, among which cell therapy and tissue engineering are relatively mature. Specifically, tissue engineering must integrate professional knowledge and technologies such as biology, medicine, and materials science to develop related products such as trauma repair, tissue reconstruction, organ reconstruction, and surgical aids (such as stents). With the maturity of 3D printing technology, after introducing 3D printing technology into tissue engineering, tissues, organs and surgical auxiliary equipment with complex structures and special functions can be gradually created. [0003] As far as the artificial biological tissue is concerned, it can be roughly divided into a membrane layer and a nuclear layer covered by t...
