ProtoCAM: Additive Manufacturing, 3D Printing and Rapid Prototyping.

Direct Metal Laser Sintering (DMLS)

Also known as metal 3D printing, the direct metal laser sintering (“DMLS”) process involves the fusing of powdered metals with an infrared laser beam. This allows for the creation of metal prototypes and production pieces with no special tooling, and rapid turnaround times.

About DMLS

Direct metal laser sintering (DMLS) is an ideal rapid prototyping solution for clients that need high-quality 3D metal parts or metal prototypes quickly.

No special tooling is required, allowing for DMLS turnaround times of one week or less. Our advanced direct metal laser sintering (DMLS) equipment allows for the creation of short-run products and prototypes in extremely complex shapes and forms.

In direct metal laser sintering (DMLS), 3D metal parts are created by fusing (“sintering”) powdered metals with the heat from an infrared laser beam. These metal layers are repeatedly laser sintered, creating the desired three-dimensional piece based on a 3D CAD model or .stl file. DMLS is an additive manufacturing sequence process, as parts gradually increase in size until they reach prescribed dimensions.

Advantages of DMLS metal 3D printing:

  • DMLS metal 3D printing uses homogenous materials, minimizing potential complications.
  • Parts produced using DMLS metal 3D printing can easily be machined, EDM processed, polished, etched, textured and more.
  • Parts can be produced using a variety of material types.

Limitations of DMLS metal 3D printing:

  • DMLS metal 3D printing typically costs much more than other rapid metal prototyping techniques.
  • Depending on part geometry, DMLS metal 3D printing presents size limitations.
