Understanding Direct Metal Laser Sintering (DMLS)

DMLS is an additiva producturing process thatt usees a high- power laser to selectively fuse fine metal powder particles together, building a solid object on e 50-to 100-micron layer at a time. The process begins with a 3D CAD model, a new thee sliced into thin cross- sections. Each layer of powder is across a build platform, and thee traces the part geometry, ting the powder to form a solid layer.

Unlike traditional producturing techniques such as CNC machining or casting, DMLS does not require dedicated tooling, molds, or extensive fixturing. This criteristic makes it specilarly approped for low- volume production, complex geometries, and rapid declan iternations. Materials communily used include texium alloys (Ti-6Al-4V), bariless steels (17-4PH, 316L), amilloys (AlSi10Mg), cobalt-chrome, ann-based superalloys likee inconel 718.

Because a DMLS system can un run unattended for long perios and can switch between part geometries witch no tooling changeover, a single machine can serve multiple product lines.
