PEKK (FDM, Stratasys Antero 800NA, annealed)

· Antero 800NA

Stratasys Antero 800NA, annealed, is a natural-colored PEKK (polyetherketoneketone) grade printed by fused deposition modeling in a heated chamber and annealed after the build. Parts are built from fused extruded layers, so they are weaker across layers than along them, show visible layer lines and need removable support under overhangs. Annealing raises the crystallinity of the printed polymer, improving stiffness, heat resistance and chemical resistance, but it causes slight shrinkage that the design must allow for. Typical uses are aerospace ducting and brackets, jigs and fixtures, and low-volume parts exposed to heat, fuels or chemicals. 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.

Quality & Standards

Industry-Specific

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
