Abstract:
Vat photopolymerization is the oldest and popular additive manufacturing technique, which can print metal and ceramic parts quickly with high dimensional accuracy. This study successfully produced a metallic alloy from elemental powders by Digital Light Processing (DLP) method. Ni-Ti-Cu powders were blended in a curable resin with a specific ratio. Then the prints were debound and sintered to obtain the final part. Finally, microstructural observation and elemental distribution were analyzed to authenticate the possibility of alloying with this technique. The results indicate that Vat photopolymerization is a fast, reliable method for producing a near net shape metal part from different elemental powders. A wide range of alloys with arbitrary chemical compositions can be made.
