Research and Application of Negative Pressure Automatic Regulating Device Based on 3D Printing

3 D printing negative pressure automatic regulating device includes:controller,negative pressure generator,negative pressure storage tank,ink cartridge and negative pressure sensor.The negative pressure generator was connected with the negative pressure storage tank for generating negative pressure.The negative pressure storage tank was connected with the ink cartridge to store a certain amount of negative pressure.The negative pressure sensor was connected to the controller and installed on the top of the cartridge to detect the negative pressure in the cartridge.The problems existing in the negative pressure system of 3 D printer were studied.The results show that the abnormal ink-jet problem is solved by using the negative pressure automatic adjusting device.The negative pressure automatic adjusting device can improve the stability of the negative pressure system,improve the quality of ink-jet and ensure the overall quality of the printed sand mould.
