Direct Metal Laser Sintering

 

Technical Description

Size

In DMLS a laser is used to draw upon a bed of metal powder. Maximum part dimension 250 mm x 250 mm x 325 mm.

Accuracy

Layer thickness 0.03 mm, smallest details 0.38 mm with most materials. Typical tolerances ±0.1 or ±0.1%.

Finishing

Surface on printed parts is somewhat harsh. Often special post-processing of DMLS components is required to create expected surface finishes and features. Precise finishing of the surfaces (e.g. lustre turning), compliance with exact tolerances, adding threads or building of sub-assemblies, is possible via our finishing services.
