Overview

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. An initial brushing is manually administered to parts to remove a majority of loose powder, followed by the appropriate heat-treat cycle while still fixtured in the support systems to relieve any stresses. Parts are removed from the platform and support structures are removed from the parts, then finished with any needed bead blasting and deburring. Final DMLS parts are near 100 percent dense.

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.
