Timeless material meets
limitless technology

Metal 3D Printing holds a unique position in modern-day product development. It allows for the direct manufacturing of complex end-use parts and facilitates tooling for conventional manufacturing technologies, reducing costs and lead times. This technology is also known as Direct Metal Laser Sintering (DMLS) and Select Laser Melting (SLM).

How Does Metal 3D Printing Work?

Metal 3D Printing is a laser-based technology that uses powdered metals. Similar to Laser Sintering, a high-powered laser selectively binds together particles on the powder bed while the machine distributes even layers of metallic powder. Support structures are automatically generated and built simultaneously in the same material, and are later manually removed. Once complete, the part undergoes heat treatment.

Why choose Metal 3D Printing?

This technology combines the design flexibility of 3D Printing with the mechanical properties of metal. From tooling inserts with cooling channels to lightweight structures for aerospace, any application that involves complex metal parts potentially benefits from Metal 3D Printing.
