SLS - Selective Laser Sintering

Selective Laser Sintering (SLS) is a rapid prototyping technique that allows the construction of parts through powder sintering layer-by-layer. There are no dimensional limits since the part is cut before production and bonded in a post-production phase with bicomponent adhesives. Maximum dimensions of a monolithic prototype are 350x330x420 mm. 

Ideal applications

Technical Specifications

  • Fully-functional parts with similar mechanical properties to injection mould ones
  • High-dimension prototypes (no limits) and complex geometries
  • Small pre-series production in replacement to moulds
  • Design-complex prototypes with honeycomb and organic structures
  • Standard tolerance: +/- 0.3 mm
  • Layer thickness: 0.12 mm
  • Minimum wall thickness: 0.8 mm PA12-based materials and 0.5 mm for TPU. However, it is possible to reproduce edges and living hinges according to par geometry and orientation.
  • Finishing and treatments: sandblasting, polishing, embossing, impregnation, metal coatings etc…
