The weldability of laser-sintered and injection-moulded plastic components was investigated for the ultrasonic and heated tool welding procedures. Polypropylene, mineral-filled Polyamide 6 as well as unfilled and glass-bead-filled Polyamide 12 served as materials. While all the heated-tool-welded joints achieved the respective reference strengths of the injection-moulded materials, this was only the case for Polyamide 12 with ultrasonic welding. In contrast, polypropylene and Polyamide 6 exhibited strength reductions up to 30%.
