Abstract:
In order to meet the application requirements of the integrated molding of multi-material biological 3D printing,it is necessary to drive the multi-material spray extrusion system accurately. Based on this,this research designs and makes a kind of air pressure control system based on the proportional modulation valve. The system sets the air pressure through the touch screen,processes the set value by the single-chip microcomputer and transmits it to the proportional modulation valve for air pressure modulation,then uses the acquisition module of the air pressure sensor for data collection,and displays the real-time air pressure through the serial screen. The system can accurately adjust and monitor the air pressure of the nozzle under the working condition by designing the relevant processing circuit and writing the data processing algorithm. The test shows that the designed multichannel air pressure acquisition system can not only meet the requirements of the pressure monitoring for the multi material biological 3D printing system,but also provide a good display interface solution for the relevant experimental platform or control equipment.
