Laser beam melting

Manufacturing beyond current process limits

We research and develop application of the additive manufacturing process laser beam melting for tool-free manufacturing of metal components with geometric peculiarities which cannot be manufactured by conventional production technologies. Novel tools and molds of steel are developed with integrated near-net-shape cooling and tempering channels for primary shaping and forming technology. Moreover, medical titanium implants with customized geometries or internal functional structures for improved healing and higher patient comfort.

Tool making – active components for forming tools

  • Near-net-shape tempering in press hardening
  • Process optimization in die casting

Component manufacturing – manufacturing beyond technological boundaries

  • Heat exchanger with optimized structure
  • Longboard carrier with optimized topology

Medical engineering and implant manufacturing

  • Implant with internal channels and cavities

  • Tool-free manufacturing– directly based on 3D CAD data
  • No costly process engineering, no NC programming
  • Direct digital manufacturing and rapid prototyping
  • Almost arbitrarily complex geometries (undercuts, internal geometries, delicate cavity structures/ framework structures)
  • Bionic structures and components with 100% optimized topology
  • Geometries that cannot be generated by cutting/forming/casting
  • Material variety (hot-work steel, stainless steel, nickel-base alloy, cobalt-chromium, aluminum, titanium)

Tool making – active components for primary shaping tools and forming tools

  • Development and manufacturing of innovative tool systems with added value such as near-net-shape tempering
