Additive Manufacturing in High Performance Plastics

Selective Laser Sintering on EOSINT P800 with EOS PEEK HP3 (PEK = Polyetherketon) suitable for prototyping and small series production.

ThermoMelt Technologie on pilot machine (as from 2017) with PPS (Polyphenylensulfid) and PEKK (Polyetherketonketon) suitable for industrial applications.

All three high performance plastics are suitable for high-temperature applications up to 200°C and are inherent flame-retardent and burn antitoxic. Besides their outstanding mechanical properties and chemical resistance they are as well adapted for electrical isolation.

More materials will follow soon. For industrial applications special customized solutions can be developed.

Knowledge and extensive experience

55 years of manufacturing expertise

Our company was founded in 1961 as a carpentry by Wilfried Rauch. Between 1994 and 2005 we specialized in milling processing of thermosetting plastics and thermoplastics. A new era was launched in 2006 when a five-axis robot was installed to feed a new machining center. Today several machining centers produce serial parts mainly for the engineering industry and medical engineering industry.

Additive Manufacturing

A new milestone was reached in 2013 when the EOSINT P800 für PEEK was installed. Right from the beginning our additive manufacturing department was specialized in high performance plastics.

Based on our roots in small series production and because of sophisticated materials our main focus is more on serial parts than on rapid prototyping.
For series applications we offer consulting for your R&D and design departments. A design matching the special facts of additive manufacturing is mandatory for a successful implementation.

Technology: New laser sintering technology „ThermoMelt“

The absolutely new laser sintering technology ThermoMelt opens a new approach to eliminate the previous disadvantages in additive manufacturing with high performance polymers. The materials get less polymerized because of the processing in low temperature. The recycling rates show significant improvement and unpowdering of the parts becomes quite simply. Additionally smoother surfaces and better tolerances are feasible. The higher recycling rates as well as the lower building chamber temperatures decrease the costs significantly for industrial applications.

ThermoMelt was developed and patented by Airbus Group Innovations. Rauch CNC Manufaktur is the industrial partner in the development collaboration. Systems engineering will be done at LSS in Dortmund . Lehmann u. Voss in Hamburg signs responsible for material development and supply. As the specialist for PEEK we yield our wide experience in optimization and processing of industrial parts with high performance plastics for laser sintering into our development collaboration.

After completion of the first tests the pilot machine will be installed at our factory in spring 2017 to pass extensive second test series with parts. During 2017 the optimized pilot machine will be available as the worldwide first commercial ThermoMelt machine for industrial applications in series production.

All three partners of this collaboration together are able to customize the processing of ThermoMelt as well as the machining technology and the materials to the needs of your industrial parts. We adapt technique and material to the component and not the reverse!

Additive Manufacturing for Space Using High-Performance Polymers

AMPFORS (Additive Manufacturing of Polymer Parts for Space) is seeking to replace the metal structural components used for space applications with lightweight polymer parts. These parts are produced by means of additive manufacturing, which is also known as 3D printing. To compensate for their lower mechanical stability compared to metal, the polymer components are then outfitted with a metallic layer to form a “sandwich” composite. AMPFORS plans to use both the high-performance polymer PEEK and the less expensive material polyamide (PA). In addition to the space sector, this project‘s key markets include aircraft manufacturing, mechanical engineering, tool-making, and medical equipment production.


  • Makes satellite structures up to 20% lighter and up to 50% less expensive
  • Incorporation of metal coatings improve the mechanical, electrical, and thermal properties of polymers; also prevents the emission of water and monomers
  • Additive Manufacturing process speeds up component design and production

RAUCH Additive Manufacturing in High Performance Plastics

Formnext 2017 - a complete success!

With 21,492 visitors at its third edition, Formnext 2017 developed to the top event of the 3D printing industry. A fundamentally new booth design also signaled our progressive growth in the field of "Additive Manufacturing".

The main interest of our visitors aimed at (oder concerned) the newly introduced SLS materials PPS and PA12 Carbon. The new technology ThermoMelt with PEKK and the PEEK-filament printing ROBOZE ONE + 400 also attracted a great deal of attention.

This year once again our visitors could assure themselves of the generative production with high-performance plastics being our passion. Thank you for the interesting discussions!

For 2018 the course is set. With new processes and new materials, we can offer optimal individual solutions for your applications.
