Abstract

The invention relates to the technical field of bio-printing, and in particular to a bio-printer and a calibration method thereof. The bio-printer of the invention includes a control apparatus, a first detection apparatus and a second detection apparatus. The first detection apparatus can send a first signal to the control apparatus when an injection apparatus moves to a first position in a Z axis direction so as to enable the control apparatus to calibrate a predetermined value of the length of the injection apparatus. The second detection apparatus can send a second signal to the control apparatus when the injection apparatus moves to a second position in the Z axis direction so as to enable the control apparatus to calibrate a predetermined value of the height of an initial attachment surface of a printing material. The bio-printer and calibration method of the invention can realize automatic calibration of the predetermined value of the length of the injection apparatus and the predetermined value of the height of the initial attachment surface of the printing material, which not only simplifies operation, lowers labor intensity of operation personnel, and also can effectively increase measuring precision, can guarantee precision consistency among a plurality of measurement, and can increase work reliability.

Description

technical field [0001] The invention relates to the technical field of bioprinting, in particular to a bioprinter and a calibration method thereof. Background technique [0002] Bio-3D printing refers to the technology of printing biological materials (including natural biological materials and synthetic biological materials or cell solutions) into designed three-dimensional structures through the principles and methods of 3D printing. Compared with ordinary 3D printing technology, the characteristic of biological 3D printing technology is that the biological tissues or organs it produces also have certain biological functions, which need to provide conditions for the further growth of cells and tissues. Therefore, biological 3D printing technology is in the The development is faced with many specific technical problems that are different from ordinary 3D printing technology. [0003] A bioprinter is a device that implements bio-3D printing technology. It uses living cells ...
