Selecting Direct Metal Laser Sintering

Direct Metal Laser Sintering (DMLS) is the most widely used additive manufacturing technology used for metal layer-manufacturing parts. DMLS has many benefits over traditional manufacturing techniques. The ability to quickly produce a unique part is the most obvious because no special tooling is required and parts can be built in a matter of hours. Additionally, DMLS allows for more rigorous testing of prototypes. Since DMLS can use most alloys, prototypes can now be made out of the same material as production components.

Benefits:
  • High resolution with extreme accuracy
Applications:

Types of DMLS Parts

Basic Model
Models that are per the process with no secondary operations except a vapor hone finish. They have the quickest delivery. Used for fit and function, mostly for engineering design reviews.
Custom Model
Custom models have a varied of post operations done. These include painting, decorating, plating, texturing and threaded inserts. Call to discuss with an application engineer.

The DMLS Process

Direct metal laser sintering (DMLS) is an additive manufacturing technique that uses a carbon dioxide laser fired into a magnesium substrate to sinter powdered material (typically metal), aiming the laser automatically at points in space defined by a 3D model, binding the material together to create a solid structure.  DMLS parts are made by a laser systematically melting or sintering a 20 or 30 micron thin layer of powdered metal on to another layer. Once a layer is finished, the sintered part descends into the powder bed. A recoater arm then passes over the freshly deposited powder before the laser begins to sinter the next layer.
