3.4 What materials can be processed with metal laser sintering or laser melting processes?
Laser melting delivers dense metal parts. The processes are developed to process commercially available metal powders. A wide variety of blends that lead to alloys can be used if the powder has been validated. The powders offered by the manufacturers of AM machines can be regarded as validated. Materials are mild steel, tool steel, stainless steel, Co-Cr alloy, titanium, aluminum, and others. Copper is supposed to enter the market.
