As-extruded HPLA/NC, HPLA/GNP, LPLA/NC, and LPLA/GNP pellets, as well as the pristine HPLA and LPLA, were directly fed into the Direct3D F30 pellet printer after drying overnight at 80°C. Pellet printing was specifically chosen because of its suitability for automated material design . To investigate the effect of nozzle temperature and extrusion flow on the printability and final properties of samples, three cylindrical specimen samples (D e :20mm, D i :15.2mm, h:20mm) of each composition were printed at varying temperatures and extrusion flows. Table shows the printing parameters. The printing speed is represented as a percentage relative to the standard speed chosen by the slicer. The extrusion flow is a multiplier expressed as a percentage. It is used to convert the millimeters determined by the slicer for a filament to be extruded into revolutions of the internal screw of the pellet printer.
