Metal laser melting

A recent innovation is the addition to our services of laser-melted precision components. Components are constructed layer by layer. The component material is in powder form and is melted together via a laser beam. More...

Laser melting is generally more cost effective than conventional procedures for one-off, customised or small series components. It is a more cost effective method for low quantity production, complex designs, and production with low material usage.

Laser melting enables the production of complex components that conventional procedures are either incapable of producing or only with extensive (manual) effort. The procedure is therefore ideal for complex lattice or netting designs, porous structures or for irregular channels within a component.

The Concept Laser machine uses CAD design data to quickly produce functional metal parts. The mechanical resilience of such parts is equal to that of parts produced by conventional methods.

Benefits of metal laser melting
  • Capable of making components that until now have been technically non-manufacturable (e.g. components with internal cooling ducts, cavities, lattice structures etc.)
  • A finished component can be made from a 3D model
  • Quick component production
  • Capable of significant weight savings and high rigidity (skeletal design)
  • No rig and tool costs involved for prototypes
  • High-quality products, low warping due to uniform component cooling
  • Tool making
  • Medical technology
  • Research and development
  • Automotive industry
  • Aerospace industry
  • Specialised engineering
  • Motor sport
