DMLS (Direct Metal Laser Sintering) is an additive manufacturing method that combines the design flexibility of 3D printing with the mechanical properties of metal. Like in the SLS process, the metal part will be created layer by layer by sintering fine powder particles to fuse them together. A major difference between SLS and DMLS is the sintering temperatures. While polyamide needs to be sintered at a temperature of 160°C to 200°C, metal melts at a temperature around between 1510°C and 1600°C meaning that a more high-wattage laser is needed to reach that temperature.

First a roller will apply a layer of metal powder, then the laser will sinter the powder as per the CAD design, upon completion of the first layer the build platform will move down and the roller will apply a new layer of powder. The process is repeated until the desired part is created. Once completed, the metal part needs to cool down before being extracted. Support structures are automatically generated and built simultaneously in the same material, and are later manually removed.

• Fully functional parts and tools

Standard Lead time: Minimum 7 working days depending on part size, number of components and finishing requirements lead time may increase.

Standard Accuracy: ± 0.3%

Layer thickness (resolution): 0.04 mm

Minimum Wall thickness: 1mm

Max dimensions: 250mm x 250mm x 300 mm. Large parts can be created by assembling individual parts by interlocking designs or gluing them together.

Surface finishing and Post Processing: Unfinished parts typically have a rough surface. DMLS parts can be hand-polished or machined surfaces upon request.
