Frequently Asked Questions

DMLS/LPBF uses a high-powered laser to selectively melt and fuse layers of metal powder to create fully dense, complex parts directly from a 3D CAD model.

Common materials include stainless steel, aluminum, titanium, Inconel, cobalt-chrome, maraging steel, and tool steels—selected based on application.

Layer thickness ranges from 20 to 60 microns, depending on material, machine settings, and desired surface finish or build speed.

DMLS can achieve tolerances of ±0.1-0.2 mm, though tight tolerances may require post-machining for critical surfaces or assemblies.

Typical post-processing includes support removal, heat treatment (stress relief), shot blasting, CNC machining, polishing, and surface treatments depending on end-use.

Inert gases such as argon or nitrogen are used to maintain a controlled environment, preventing oxidation and ensuring consistent metallurgical properties.

Parts printed using DMLS/LPBF are near fully dense (up to 99.9%) and can match or exceed the mechanical properties of traditionally machined or cast components.

Yes, but overhangs below 45° usually require support structures. Complex internal channels may require build orientation and support removal planning.

Orientation impacts strength, surface quality, support requirement, and build time. Proper orientation helps optimize mechanical properties and reduce post-processing.

Requirements include 3-phase power, inert gas supply (argon/nitrogen), a powder handling system, climate-controlled space, and safety equipment for metal powder handling.
