Heated volumetric extrusion mechanism with co-axial Auger and Moineau pumps for 3D printing from plastic pellets

The higher cost and lower availability of the thermoplastic filaments -compared to pellets- make FDM 3D printers underutilized in developing countries. We designed a solution to use easily sourced plastic pellets with precise volumetric control of the extrusion flow. This is done by a rotor mad...
