Powered By DMLS
Direct Metal Laser Sintering (DMLS) is a laser-based technology of metal 3D printing that uses powdered metals. 3D printing with metal is the ideal alternative to complex designs that machining or casting can’t achieve as it offers the mechanical properties of aerospace standard materials and the design freedom of additive manufacturing.
