Stratasys unveils new PEKK-based high-performance thermoplastic of interest to aerospace sector

2 mins read

​3D printing machine/software/material provider Stratasys has added a new PEKK-based high-performance thermoplastic, called Antero 800NA, for its FDM process.

A PEKK material for FDM additive manufacturing offers significant advantages for many manufacturers, including lighter weight parts, reduced inventories and improved profitability.

Aerospace and other high-performance vehicle makers wishing to move to an additive manufacturing process will be among the most interested in Antero 800NA.

Antero 800NA outperforms other high-performance thermoplastics with its superior chemical resistance and ultra-low outgassing. In addition, the material possesses high temperature resistance and exceptional wear properties.

Its superior 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.

Unlike PEKK parts made with some powder-based additive processes, Antero 800NA parts created with the FDM process are more durable and dimensionally stable, even when building large parts.

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 optimised topology and significantly reduced waist.

Another important advantage with the additive process is it allows manufacturers to produce PEKK parts on-demand and eliminate inventory that might sit on a shelf for years before being needed. The reduction in inventory costs means increased profitability.

Besides space, aerospace and automotive, target industries include high-end industrial manufacturing, as well as oil-and-gas applications.

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 0.25 mm and additional layer-thickness options planned for future release.

Antero 800NA is expected to be available for use on Stratasys’ Fortus 450mc Production 3D Printer in Q2, 2018, and for the Fortus 900mc Production 3D Printer in Q4, 2018.

Existing Fortus 450mc users with the high-performance material bundle will be able to use Antero 800NA without additional licence fees. Fortus 450mc users without the high-performance materials bundle can purchase the high-performance material bundle or an individual material licence. Fortus 450mc systems will require the Nylon 12CF hardware upgrade, along with a new tip and purge ledge to operate the Antero 800NA material.
