Nozzle with Pressure and Force Sensing

A pressure detector is installed in close proximity to the nozzle of a 3D printer and detects a plugged nozzle by the sudden increase in the pressure of the extruded material. The printing process is paused until the nozzle is cleared manually or automatically. For manual cleaning a notification can...

More Information
Summary:A pressure detector is installed in close proximity to the nozzle of a 3D printer and detects a plugged nozzle by the sudden increase in the pressure of the extruded material. The printing process is paused until the nozzle is cleared manually or automatically. For manual cleaning a notification can be automatically sent to the user of the printer. The pressure sensor can be part of the nozzle housing and be designed to detect external forces as well, in order to serve as a bed levelling sensor.
