FAQ

COMMON QUESTIONS

What is DMLS vs SLM?

DMLS (Direct Metal Laser Sintering) and SLM (Selective Laser Melting) are both laser powder bed fusion processes. The key difference: SLM fully melts the powder for near-100% density, while DMLS partially sinters. We use both depending on the material and application.

How strong are DMLS parts vs machined metal?

DMLS parts typically reach 95–99.9% density with mechanical properties comparable to wrought or cast equivalents. After HIP treatment, fatigue properties match or exceed billet. Titanium DMLS parts are certified for aerospace and medical use.

Do metal parts need support structures?

Yes. Unlike SLS plastic, metal DMLS requires support structures for overhangs > 45° and to conduct heat during printing. Supports are machined off as part of post-processing. We design supports to minimize material use and post-processing time.

What's the minimum wall thickness?

Minimum wall thickness is 0.3–0.5 mm depending on material. Titanium and stainless steel can go thinner than aluminum. We review every file for printability before production.

Can you machine critical surfaces after printing?

Yes — we offer post-print CNC machining for tight-tolerance bores, threads, and mating faces. This hybrid approach gives you the geometric freedom of DMLS with machined-grade tolerances where it counts.
