Abstract

The invention relates to an inkjet head assembly of a biological printer and the biological printer. The inkjet head assembly of the biological printer comprises an outer inkjet nozzle with a second channel and an inner inkjet nozzle with a first channel; the inner inkjet nozzle is coaxially arranged in the second channel; a first material channel is formed by the first channel; a second material channel is formed by an annular space between the outer inkjet nozzle and the inner inkjet nozzle; the second material channel surrounds the first material channel at an outlet of the first material channel and is used for enabling second materials ejected from an outlet of the second material channel to gather towards first materials ejected from the outlet of the first material channel so as to form a fluid printing unit. According to the inkjet head assembly, the second materials are uniformly coated with the first materials at the outlet of the inkjet head assembly, so that the fluid printing unit with higher quality is formed for protecting the cells, further cell damage caused by an extrusion pressure and a frictional force in the printing process is reduced, and the survival rate of the cells is improved.

Description

Technical field [0001] The invention relates to the field of biological printing, and in particular to a nozzle assembly of a biological printer and a biological printer. Background technique [0002] Biological 3D printing refers to the printing of biological materials (including natural biological materials and synthetic biological materials or cell solutions) into a designed three-dimensional structure through the principles and methods of 3D printing, which is different from ordinary 3D printing technology and biological 3D printing technology production Biological tissues or organs also have certain biological functions and need to provide conditions for the further growth of cells and tissues. It is precisely because of the above characteristics that biological 3D printing technology is facing many specific technical problems in the development. [0003] Among them, in the field of biological 3D printing, the technology that uses cells as printing materials is called cell thr...
