Vacuum Monitoring of Smoke and Gas Extraction in 3D Printers with Pressure Sensors
Printing plastics or metal in 3D printers creates harmful fine dust, gas, smoke or combustible dust. These pollutants must be extracted from the pressure area in a controlled manner, filtered and disposed of in order to protect the safety of the workers. For this purpose, a vacuum is generated in the pressure chamber. This partial vacuum must be continuously monitored by a pressure sensor. Due to its low housing height of only 22 mm, the pressure sensor in miniature design is ideally suited for installation in compact 3D printers.
