Evonik’s implantable PEEK filament for medical applications in 3D printing.
Evonik has launched a 3D printable PEEK filament as an implantable material for medical applications.
Custom plastic implants can now be designed and manufactured using additive manufacturing processes that meet the requirements of ASTM F2026 (the standard specification for PEEK polymers for surgical implant applications).
This PEEK filament is sold under the brand name VESTAKEEP i4 3DF and is an implant-quality material based on VESTAKEEP i4 G, a high-viscosity, high-performance polymer from Evonik. The company highlights the biocompatibility, biostability, X-ray transparency and ease of use of the product as the main features. The filament is manufactured under clean room conditions and then subjected to strict quality management standards for medical materials.
The high-performance material was developed for FFF technology (Fused Filament Fabrication). The natural colored PEEK filament with a diameter of 1.75 mm is wound on 250 or 500 gram spools, which are suitable for direct use in standard FFF 3D printers for PEEK materials.
In addition to its implant quality, Evonik also offers a test version of its PEEK filament. The term refers to a material class with exactly the same product properties as the implant quality, but without the documentation required for approval in medical technology applications. This offers a cost-effective way of adapting the processing properties of the high-performance plastic to a specific 3D printer.
