Stratasys Offers PEKK-Based Antero 800NA for High Performance

Stratasys offers a PEKK-based high-performance thermoplastic, called Antero 800NA, for lighter-weight parts and improved profitability. Antero 800NA offers chemical resistance and low outgassing, as well as high temperature resistance and wear resistance. The material is suitable for aerospace and high-performance vehicle applications, among others.

The material’s high chemical resistance means it can be used for components exposed to hydrocarbons, such as fuels and lubricants, as well as many acids. Additionally, its low outgassing allows it to be used in confined spaces and sensitive environments, such as satellites, where materials may not outgas under vacuum. Antero 800NA’s high operating temperature is designed to allow it to be used for applications under the hood or in engine compartments.

According to Stratasys, custom or low-volume additive manufacturing with Antero 800NA has economic advantages over traditional machining processes. With traditional processes, manufacturers buy bulk PEKK (available only in limited shapes and sizes) and machine it to a net shape, which wastes a considerable amount of expensive material and has a longer lead time. With an additive process, the workflow is faster, yielding lighter-weight parts with optimized topology and significantly reduced waste.

Antero 800NA is the first commercial product in a planned new family of PEKK-based materials. The material will be offered with an initial layer thickness of 0.010" (0.25 mm) and additional layer-thickness options planned for future release.
