The invention discloses a 3D biological printer for controlling printing distance based on image processing. The 3D biological printer for controlling printing distance based on image processing comprises a PC upper computer and a 3D printing lower computer; the PC upper computer comprises a control module, an image processing module and a display module; the 3D printing lower computer comprises aprinter body as well as a stepped motor, a guide rail, a spray head pedestal, a spray head, a forming workbench and a camera which are arranged in the printer body; the camera is connected with the image processing module; the image processing module processes the acquired image to acquire the distance between the spray head and a printed target tissue and transmitting the distance to upper computer software to process; and the PC upper computer software displays the received data in real time, controls the 3D printing lower computer and adjusts the printing distance. The printer maintains the distance between the spray head and the biological tissue to be between 200 and 300 microns so as to overcome the problem that the printing precision is not high.
Description
technical field [0001] The invention relates to a 3D bioprinter for controlling printing distance based on image processing, which belongs to the technical field of biological tissue engineering. Background technique [0002] 3D printing is a kind of rapid prototyping technology. It is a technology based on digital model files and using bondable materials such as powdered metal or plastic to construct objects by layer-by-layer printing. Tissue engineering integrates engineering, life science, and material science. By simulating the formation process of human tissues and organs, biologically active structures can be constructed and cultivated in vitro. Among them, 3D printing technology has become the most powerful research method in the field of tissue engineering because it can use a variety of materials to form any complex three-dimensional structure. The principle of 3D printing technology is layer-by-layer manufacturing and layer-by-layer accumulation. [0003] 3D biop...
