Laser Sintering of High Temperature Metals and Plastics

U. Behrendt, EOS GmbH Electro Optical Systems, Krailling, Germany

Laser Sintering with new high temperature materials.

A long time the use of layer manufacturing technologies for production purpose was strictly limited by the available materials. Step by step continuous development improved the technology and achieved higher productivity, better material properties, long lifetime of parts and the cost situation.

Especially the low numbers and the long product life time in the aerospace market require new production methods.

Applications like air duct's or jet engine parts are already used in the industry since a long time.

New high temperature materials i.e. PEEK or Inconel 718 open up new market segments and are key factors for the break through of this technology.

Advantages of fast and flexible production combined with excellent material properties help to reduce some of the problems with aging fleet's and spare part supply.

Potential and vision for new material development in laser sintering technology.


Summary: Especially the Aerospace industry requires materials with excellent mechanical and temperature specifications. Layer manufacturing technologies like Laser Sintering take an increasing part of small serial production. Applications like air ducting or jet engine parts are already used in the industry. New polymer materials like PEEK or metals like Inconel 718 open up market segments in the Aerospace industry. Advantages of fast and flexible production combined with excellent material properties help to reduce some of the problems with aging fleetīs and spare part supply. New market segments like UAVīs require new production approaches.
