Learn about Direct Metal Laser Sintering (DMLS) technology and rapid 3D prototyping.

What is DMLS?

Direct metal laser sintering (DMLS) is an additive metal fabrication technology, occasionally referred to as selective laser sintering (SLS) or selective laser melting (SLM). This process utilizes a 3-dimensional CAD model, creating a file which is then forwarded to the software utilized by the machine.

The operator utilizes the aforementioned 3-dimensional model to correctly align the geometry for the purpose of building parts and implements support structures wherever necessary.

The direct metal laser sintering machine makes use of a powerful fiber optic laser. Within the build chamber is a platform for material dispensation and a build platform, in addition to a recoater blade which moves new powder on top of the build platform. With a focused laser beam, this DMLS technology melts metal powder locally to fuse it into solid parts. Parts are constructed additively, one layer at a time. Each layer is usually 40 micrometres thick.

This direct laser metal sintering process facilitates the creation of very complex geometries derived from 3-dimensional CAD data. The process is completely automated and is usually completed within just a few hours. DMLS is a net-shape process, accurately creating parts that yield, high resolution, great surface quality and excellent mechanical properties.

Current materials available include Inconel 625, Inconel 718, Cobalt Chrome, Aluminum and Titanium other material available upon request.
