...dy reactions can be avoided. The substances added to the composites, such as calcium phosphate, support bone regeneration and so accelerate the healing process. Polyesters of Superior QualityThe bioresorbable polymers marketed under the brand name Resomer by Evonik Nutrition & Care GmbH belong to the polyester family. This is the largest group of polymers used for medical devices and pharmaceuticals. They are applied especially for suture material, orthopedic implants, and intelligent systems fo...

... medical challenges. In accordance with the boundary conditions for processability and medical requirements, suitable materials were selected from existing, commercially available resorbable polymers. These were poly-L-lactide (PLLA) (grade: Resomer L207, manufacturer: Boehringer Ingelheim Pharma GmbH & Co. KG) and poly-L-lactide-co-trimethylene carbonate (70:30) (PLLA-co-TMC) (grade: Resomer LT706). The compatibility and degradation behaviour of both these materials in the human body have been ...

...the wax model. Pouring takes place in a centrifugal furnace after which the implant is turned to the required length in a downstream operation before being media blasted. Following this the Mg skeleton is infiltrated with poly-ε-caprolactone (PCL Resomer Sample MD Type C from Evonik Industries AG, Essen, Germany) in an infiltration tool. This material has excellent biocompatibility and elasticity. The second process step was to foam the implant using the CESP (Controlled Expansion of Saturated...

In a second medical technology application, implants were molded from a resorbable polylactide (PLA; grade: Resomer; manufacturer: Evonik Industries AG). A screw coated with chromium nitride and having widened flight lands ensured that the material was prepared gently, without undesirable deposits.The same PLA, which slowly degrades in the body, was also processed on a Freefor...

It also contains special plastics for specialized applications such as medical-grade PLLA (type: Purasorb PL18 and Resomer LR 708; manufacturer: Corbion or rather Evonik) as well as a PC approved for aerospace applications (Lexan 940, Sabic), for example. The range of qualified materials is continuously being expanded. In the Arburg Prototyping Center (APC) at the German h...

...one of the first companies in the world to offer 3D-printable medical-grade filaments for long-term implants. These consist either of the high-performance polymer PEEK, offered under the brand name Vestakeep, or of resorbable polymers of the Resomer brand family, which may contain polylactide as a constituent. In order to materialize the potential of 3D printing in the medical field the collaboration of all players in the value chain is essential. Over the last few years, for example, Evonik ha...

Thus, implant plates of the resorbable, FDA-approved original material Resomer LR 706 – a composite of poly(L-lactide-co-D,L-lactide) and β-TCP (manufacturer: Evonik Nutrition & Care GmbH, Essen, Germany) – can be manufactured, which can be used directly in the body on bone fractures (Title figure). The polymer composit...
