Title: Filament Supply Sensing and Control for FFF/FDM 3D Printing Technology Keywords: 3D printing; Additive manufacturing; Additive technologies; Abstract: In this work, four innovative methods for filament supply control in 3D printing FFF/FDM technology are presented and analyzed. These filament supply methods are used to detect and avoid 3D printing process blocking caused by extruder jamming. The first method is based on a real-time temperature feedback from the 3D printer extruder. The second method follows the dynamics in the extruder heater switching frequency. The third method is suitable for electrically conductive filaments and measures material resistivity against the printing bed. The fourth method measures the extruder to printing bed capacitance. Examples of algorithms for each method are analyzed and recommended for possible implementation of the control G-code of 3D printing programming. The methods and principal algorithms use data sets provided by direct measurements during the 3D printing process. The proposed methods could give significant benefits in energy efficiency and optimal material usage of 3D printing. References Issue
