The ColdMetalFusion process is known for reliable serial production in metal AM with high part quality. With ColdMetalFusion, Headmade Materials combines standard PM metal powders with its proprietary binder system to form a powdery feedstock that can be processed into green parts on standard plastic laser sintering systems. The subsequent debinding and sintering step also follow the PM industry standards and the part characteristics are fully comparable to MIM in terms of density and strength. Due to the high green part strength, the surface can already be post-processed as green part before sintering. Standard processes like grinding, blasting and machining can be used, which saves time and costs. Surface roughness of Ra of 1 µm and below can be achieved by cost-efficient post processing methods.
