![]() FURTHER INFORMATIONĮvonik’s biomaterials for 3D printing COMPANY INFORMATIONĮvonik is one of the world leaders in specialty chemicals. In addition to VESTAKEEP® i4 3DF, the portfolio includes the RESOMER® line of bioresorbable filaments, powders and granules for implantable medical devices. The specialty chemicals company offers the industry’s most extensive portfolio of GMP-grade biomaterials used in the 3D printing of medical device parts designed for temporary and permanent body contact. This offers a cost-effective way of adapting the processing characteristics of the high-performance plastic to a given 3D printer.įor more than 20 years, Evonik has been the world’s leading manufacturer of high-performance polymers and additives used in additive manufacturing. The term refers to a class of material having the exact same product properties as the implant grade, but without the documentation needed for approval in medical technology applications. In addition to its implant grade, Evonik is also offering a testing-grade version of its PEEK filament. Therefore, we will successively expand our product portfolio of 3D printable biomaterials.” TESTING GRADE ENABLES COST-EFFECTIVE PROCESS ADAPTATION ![]() “Innovative high-performance materials like Evonik’s VESTAKEEP® PEEK-along with highly complex hardware and software, and the perfect match between materials and machines-form the basis for a sustainable 3D-printing revolution in medical technology. Orthopedics and maxillofacial surgery are examples of areas where this could be applied,” says Marc Knebel, who heads the Medical Devices & Systems market segment at Evonik. ![]() “For modern medical technology, the development of our first 3D-printable implant material opens up new opportunities for customizing patient treatments. The natural-colored PEEK filament, which has a diameter of 1.75 mm, is wound on 250- or 500-gram spools suitable for direct use in standard FFF 3D printers for PEEK materials. The high-performance material was developed for fused filament fabrication (FFF) technology. PEEK FILAMENT FOR FUSED FILAMENT FABRICATION The filament is produced under cleanroom conditions and then subjected to stringent quality management standards for medical materials. Customers will be impressed by the product’s biocompatibility, biostability, x-ray transparency, and easy handling. Sold under the brand name VESTAKEEP® i4 3DF, this PEEK filament is an implant-grade material based on VESTAKEEP® i4 G, a highly viscous, high-performance polymer from Evonik. Bushings used in the mining, pulp, and paper industries are also made from this high-temperature polymer.In so doing, the specialty chemicals company is setting new standards for developing and manufacturing custom-made plastic implants, which can now be created using additive manufacturing processes that meet the requirements of ASTM F2026 (the standard specification for PEEK polymers for surgical implant applications). Thanks to these properties, PEEK is gaining ground and replacing such materials as aluminum, titanium, and steel in aircraft construction and in bearing and gear parts. Substituting metal parts with VESTAKEEP® PEEK reduces component cost due to improved durability, more efficient processing methods, part consolidation, and greater design freedom than is possible for machined metal parts.Lightweight construction components help save fuel in transport, and allow the construction of more durable compressor parts and more efficient engine design for gears and impellers. ![]() VESTAKEEP® PEEK is more rigid than steel and weighs less.The high-performance polymer also reduces abrasive wear arising from slurries, particulate impact, and sliding friction.PEEK components are resistant to corrosion caused by salts, solvents, caustics, and many acids.These benefits derive from the material properties of corrosion resistance, abrasion resistance, high rigidity combined with low weight, and versatile processability. VESTAKEEP® PEEK outperforms metals by improving system durability and lowering component manufacturing costs. ![]()
