Additive Manufacturing in High Performance Plastics

SLS
Selective Laser Sintering on EOSINT P800 with EOS PEEK HP3 suitable for prototyping and small series production.

FFF
Fused Filament Fabrication with PEEK, CarbonPA and other Filaments. For Prototyping and small series production. Parts impossible to be produced with SLS or OTM maybe printed with this technologie.

OTM
OligoThermoMelt Technologie on pilot machine with PPS (Polyphenylensulfid) and PEKK (Polyetherketonketon) suitable for industrial applications.

All these 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, the perfect choice of materials and technology, an optimized production process and finally a well-optimized quality-management-workflow is mandatory for a successful implementation.

With our expertise in 3D-Printing High-Performance-Plastics, we are the perfect partner to realize your most challenging projects. Ensure your company a technological and competive advantage - we have the KnowHow !

„OligoThermoMelt"

(OTM)

 

The absolutely new laser sintering technology OligoThermoMelt opens a new approach to eliminate the previous disadvantages in additive manufacturing with high performance polymers. The new process was developed and patented by Airbus Group Innovations. With assimilated temperature control, increased laser power and structured part placement with supportstructures the powder get less polymerized. The final sintering of the parts takes place through a special exposure laser strategy. The changed process leads to an improvement of the recycling rate and unpowdering of the parts becomes quite simply. Additionally smoother surfaces and better tolerances are feasible. Excellent material properties increase the quality of the parts and the higher recycling rate will reduce costs in industrial applications.

Rauch CNC manufactory is the first industrial user of this technology. The pilot machine was installed at the end of 2017 in our advanced manufacturing facility. As a proven specialist in the 3D-processing of high-performance plastics, we bring our extensive experience into further development and optimization. As soon as the test series are completed, the world's first commercial OligoThermoMelt-System will be available for mass production.

This technologically advanced infrastructure, the specially designed material concept and a broad-based expertise offer the best prerequisites for realizing the process as well as the machining technology and the materials to the needs of your industrial application in the field of high-performance plastics.

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.

Benefits:

  • 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 concerned in the newly introduced SLS materials PPS and PA12 Carbon. The new technology OligoThermoMelt (OTM) with PEKK and the PEEK-filament printing ROBOZE ONE + 400 also attracted a great deal of attention. Thanks for your visit and the interesting conversation.

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.
