Direct Metal Laser Sintering (DMLS)

Direct Metal Laser Sintering (DMLS) is an additive layer manufacturing process using fine powders to directly build metal components.

Direct Metal Laser Sintering (DMLS) is an advanced additive manufacturing process that uses fine metal powders and high-powered lasers to produce complex, high-performance metal components directly from CAD data.

3DDC provides precision DMLS services for both prototype development and low-volume production, enabling manufacturers to create lightweight, intricate geometries that would be difficult or impossible to achieve through traditional machining methods.

Our experienced team can advise on material selection, part optimisation and post-processing requirements to ensure the best outcome for your project.

Advantages of Direct Metal Laser Sintering (DMLS):

  • Powerful additive manufacturing process allowing design driven manufacturing
  • Thin wall and hollowing of components
  • Pressure tapped components & cooling channels
  • Fully dense, high performance materials
  • Substantial waste savings over machining
  • DMLS offers flexible batch production
  • Ideal for one-off prototypes and low volume production
