Abstract:In this study, a proprietary powder‐fed 3D printer is employed to fabricate impellers from metal‐polymer mixtures via low‐temperature extrusion, simplifying the traditional complex metal molding process. By adjusting the extrusion speed and temperature, various quality impeller blanks are produced, identifying optimal printing conditions. The best results are achieved with a feed temperature of 170 °C, extrusion speed of 6 r min−1, printing platform temperature of 50 °C, and nozzle temperature of 175 °C, achie… Show more
