DMLS Overview

Direct Metal Laser Sintering Overview
DMLS Machine

DMLS is an additive manufacturing process used to create metal parts with complex geometries that are difficult to cnc machine. The EOSINT M 280 is the newest DMLS machine from EOS. It builds parts in 20-40 micron layers by melting fine metal powder with a laser beam.

Advantages of DMLS include the ability to build extremely complex geometries from CAD data including free form surfaces, deep groves, and cooling channels within injection molding tooling. DMLS also reduces turnaround time and many parts can be delivered in under a week.

The system operates in both nitrogen and argon atmospheres allowing a wide range of metals to be offered including aluminum and titanium. Parts built using DMLS have excellent mechanical properties, high detail resolution, and exceptional surface quality.

DMLS is ideal for a variety of industries including:

  • Medical
  • Aerospace
  • Defense
  • Automotive
  • Manufacturing
