Streamline your manufacturing with precision metal prototypes and low-volume metal production parts that would be impractical or cost prohibitive to machine. We create metal parts using a fiber laser fired onto a metal plate, repeatedly adding layers of powdered metal and fusing them to previous layers. Although the resulting part is accurate with excellent surface quality and mechanical properties, additional post-processing is also available.

General tolerances for DMLS parts are ±0.005 inch for the first inch and ±0.002 inch per inch thereafter (±0.2 percent), but +/-0.002 inch is achievable in some materials. If CNC tolerances are required, parts will require post-machining.

In-House Post-Processing

  • Support removal
  • CNC secondary machining (critical dimension and re-qualification)
  • Tapping, threading, and helicoils
  • Vibratory polishing and surface treatment
  • Annealing and age hardening
  • Painting and finishing

Midwest Composite Technologies uses EOS and SLM build platforms.

  • The build volume for the SLM is 11 x 11 x 13.8 inches
  • The build volume for the EOS is 9.85 x 9.85 x 8.5 inches

Materials include:

  • Stainless steel
  • Maraging steel
  • Inconel
  • Aluminum
  • Titanium
  • Other materials available on demand
