This research aims to design a prototype extrusion machine for making 3D printing filaments. The design process starts with collecting requirements data, setting the scale, calculating, selecting components, making assembling drawings and detailed drawings. The resulting extrusion machine specifications have dimensions of length of 800 mm, width 400 mm, and height of 886 mm. The extrusion machine consists of the main components of a screw conveyor, barrel, hoper, pulley-gearbox reducer, heating element, drive motor, control board, and frame. The heating process in the barrel can be regulated from room temperature to 300 °C, using PID (Proportional-Integral-Derivative) temperature control. The rotational speed of the extrusion screw can be adjusted from 0 - 22 rpm, using a VFD (Variable Frequency Drive) speed controller. The driving motor uses a single phase AC motor, 600 watts with an output torque of 234.17 Nm. The average filament production capacity is 1.2 Kg/hour. The resulting filament has a maximum diameter of 1.75 mm. © 2025 Author(s).
