PEKK (FDM, Stratasys Antero 800NA)

Stratasys Antero 800NA is an unfilled PEKK (polyetherketoneketone) filament grade printed by fused deposition modeling in a heated build chamber. Printed parts are anisotropic: they are weaker across layers in the build direction than along the deposited roads, and they show visible layer lines and some porosity between roads. Overhangs need support structures that are removed after printing, and surfaces that need tight tolerances or smoothness are usually machined. The grade is used for lightweight, chemically resistant end-use parts and tooling such as aerospace ducting, brackets, housings and fixtures. Every value on this page is read from Stratasys' own material data sheet — quoted, cited and dated — and is the maker's statement about printed material, not a measurement by MatWorld; none has yet been reviewed by a person.
