How Direct Metal Laser Sintering Works
DMLS builds metal components layer by layer using a high powered fiber laser to selectively fuse fine metal powder. Each layer is spread across the build platform, fused according to the CAD geometry, and repeated until the part is complete.
The surrounding unfused powder supports complex geometry during printing, allowing internal passages, lattice structures, and highly optimized part designs without traditional tooling limitations.
