Metal 3D Printing for Production Parts

Improve strength, dimensional accuracy, and cosmetic appearance of end-use metal components

Looking for an additive manufacturing solution for production projects? With our metal 3D printing technology, you’re able to choose from several  secondary processes like post-process machining, tapping, reaming, and heat treatments that produce end-use production parts. To ensure high-quality parts, we also offer powder analysis, material traceability, process validation, and inspection reporting, and our direct metal laser sintering (DMLS) 3D printing process is ISO 9001 and AS9100D-certified. It’s industrial 3D printing designed around your project needs—whether prototyping or production.

Certified testing to confirm mechanical requirements on production parts.

  • Tensile
  • Rockwell Hardness
  • Fatigue
  • Vibration

Heat Treatments
Specialized heat treatment processes improve the mechanical properties of parts by relieving internal stresses that develop during the sintering process.

  • Stress relief
  • Hot isostatic pressing (HIP)
  • Solution annealing
  • Aging

Quality Inspections & Reports
Validate part geometry and evaluate material structure for quality reporting.

  • Dimensional inspections with ballooned report
  • First article inspection (FAI) per AS9102
  • CMM, optical, and CT scanning
  • X-ray
  • Surface roughness

Materials and Equipment for Metal 3D Printing


Materials

  • Aluminum / ALSi10Mg
  • Cobalt Chrome
  • Inconel 718
  • Stainless Steel 17-4 PH
  • Stainless Steel 316L
  • Titanium / Ti 6AL-4V

Equipment

We use Concept Laser Mlab and M2 machines for DMLS production that offer large build sizes, produce accurate parts, and provide quick turnaround times. Mlabs are ideal for manufacturing metal components requiring improved surface quality and fine component structures. Concept Laser M2s offer larger build platforms ideal for higher part volumes. All of our additive manufacturing equipment handles both reactive and non-reactive metal powder.
