Unique materials for additive manufacturing enabling new series application

Abstract

In laser powder bed-based metal 3D printing, the high cooling rates in the process have advantages or disadvantages depending on the used material. For unique materials like amorphous metals the high cooling rate is a big advantage. However, the high cooling rates can also lead to very high stresses in other materials like titanium. Preheating the system to 500°C enables the processing of special titanium alloys such as Ti6242.Applying additive manufacturing to conventionally produced parts allow the combination of multiple materials. The feasibility of material combinations using this technique depends on individual material properties. With adapted process strategies, different materials can be combined.
