Abstract
The invention relates to a multicomponent three-dimensional organism printing device and method based on multi-channel nozzle. The device comprises a multi-channel nozzle which is located on a three axis stepper motor. The multi-channel mozzle is made of multiple nozzles arranged in parallel. One end of all micro-channels is aligned to form the nozzle, and the other end is connected with all liquid storage containers through Teflon pipes. All liquid drive devices are connected with all the liquid storage containers to drive the liquid in the liquid storage containers. A terminal control system controls the three axis stepper motor, all the liquid drive devices and temperature control devices to make the multi-channel nozzle move correspondingly and eject ink, thus achieving the three dimensional printing on a temperature control substrate. The device can precisely adjust the proportion of different ink types through controlling the ink feeding speed of all the channels. The printed artificial tissues and cells are more close to the actual tissues or organs, thus making the device have a broader application prospect compared with the prior art of tissue engineering.
