Metal Additive Manufacturing

WJW is a specialized service provider for laser melting with the highest standards

  • Design support – optimizing components for 3D printing
  • Metal 3D printing using the SLM process (Selective Laser Melting)
  • Removal of support structures and surface finishing
  • Post-processing – CNC milling and turning
  • Vibratory grinding of channels and internal structures

Selective Laser Melting

Reliable, on schedule, and flexible with our modern machine park

  • 3 SLM systems
  • Work area 245 x 245 x 400 mm
  • Dual laser manufacturing
  • Build plate heating for higher dimensional accuracy
  • QM-Coating, an image after each layer

Inconel, Aluminum, Stainless Steel / Tool Steel

We manufacture components using the SLM process from various materials

Selective laser melting employs numerous materials. Components that were previously unmanufacturable can now be realized.

Component creation is rapid, directly from the 3D model to the finished piece, without the need for fixture construction and the associated costs and effort.

Tolerances and Surfaces

Quality-conscious, economical, and efficient work

  • Tolerances up to +/- 0.05 mm, depending on component size, geometry, and layer thickness
  • Contours and surfaces can be mechanically post-processed
  • Surface quality from Rz 20 – 45 µm, depending on the material, as well as the layer thickness or build rate and orientation of the surface to the build plate
  • Surfaces of internal channels can be processed to Rz 5 µm using flow vibratory grinding
  • Image-guided 3D coordinate measuring device for quality control
