Stratasys has launched a new material – a PEKK-based high-performance thermoplastic called Antero 800NA – for 3D printing high-temperature, chemical-exposed parts, such as those in aerospace.
The company says the material offers advantages for manufacturers, such as lighter-weight parts, reduced inventories and improved profitability.
A statement notes: “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.”
It adds: “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’s 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.
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 in (0.25mm) 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.
