Dedienne Multiplasturgy Group acquires first EOS P 810 for carbon fiber PEKK

Dedienne Multiplasturgy Group, a French company specialized in the design and manufacture of high-performance plastic and composite technical parts for metal replacement is the first French manufacturer – on one of the very first in the world – to install an EOS P 810 laser sintering system for EOS HT-23 material (based on Kepstan PEKK, the extreme polymer from Arkema, reinforced with carbon fibers.

Dedienne Multiplasturgy Group has been developing a very advanced know-how in working with high-performance thermoplastics including Arkema‘s PEKK and other products but also SABIC’s Ultem and Victrex’s PEEK, producing a continuous stream of innovations.

In this context, the Group is in the process of creating a complete “Atelier Dedienne 3D” for additive production-oriented manufacturing in small and medium-sized series. In April 2019, the first machine was put into service, allowing for series in additive manufacturing based on Rilsan® Polyamide 11, a high-performance bio-based polymer, derived entirely from sustainable castor oil and manufactured by Arkema.

In October, the “Atelier Dedienne 3D” will add the EOS P 810 machine to produce EOS HT- 23 parts, an EOS powder made from Kepstan PEKK, the extreme polymer supplied by Arkema, and reinforced with carbon fibers. EOS P 810 is the first laser sintering solution for mass production of demanding high-temperature PEKK polymer functional parts.

Dedienne Multiplasturgy Group thus becomes the first French manufacturer delivering functional parts and components internationally using this material and the system that supports it. With a construction volume of 700 x 380 x 380 mm, the EOS P 810 allows for fast and economical production of high-performance techno polymer parts directly from CAD data, without the need for tooling. EOS HT-23 parts offer high strength at low weight and withstand temperatures well above 200°C. They can also be metalized to provide electrical continuity or serve as electromagnetic shielding, technologies that are mastered and implemented internally by Dedienne Multiplasturgy Group.

This new technological approach fits ideally with Dedienne Multiplasturgy Group’s focus on providing solutions for lighter parts and metal substitution. In particular for the demanding requirements of the aerospace and defense sectors. The first laser sintered Kepstan PEKK parts produced are on display at the company’s booth at the Paris Air Show, Hall 2b E50.
