FDM material
Antero 800NA PEKK overview
Antero 800NA is a PEKK plastic for FDM 3D printing, used as a lighter alternative to metal for aircraft, spacecraft and industrial parts that face harsh fluids, heat or vacuum. It has the highest chemical resistance available in FDM, standing up to jet fuel, hydraulic fluid, acids and bases, and it gives off so little gas in vacuum that it suits hardware near spacecraft optics and sensors. It also meets aircraft flame, smoke and toxicity requirements for cabin parts. Typical uses include cabin ducting, brackets, satellite mounts, pump and valve parts and engine-bay housings.
How Antero 800NA PEKK is manufactured
Antero 800NA PEKK is manufactured using Fused Deposition Modeling (FDM) on the high-temperature Stratasys F900, which builds parts layer by layer with breakaway support for overhangs. The large build envelope produces long ducts, housings and fixtures in one piece. Combined with the material's chemical resistance and low outgassing, FDM makes Antero 800NA a practical route to functional components for spacecraft, aircraft and chemical processing equipment.

Industry applications
Industry applications for Antero 800NA PEKK
Antero 800NA brings PEKK (polyetherketoneketone) chemistry to FDM, delivering high strength and wear resistance for the most demanding applications, with outgassing low enough for space and vacuum hardware. It meets FAR 25.853 and the Boeing BSS 7238 and 7239 requirements for aircraft interiors.
With a glass transition temperature of 156 °C and the highest chemical resistance available in FDM, Antero 800NA survives jet fuel, hydraulic fluid, acids and bases that destroy standard thermoplastics. Its very low smoke density in burn testing suits confined spaces such as aircraft cabins, and it serves aerospace, space, oil and gas, chemical processing, automotive and defense equipment.
From rapid prototyping to production runs, teams rely on Antero 800NA to maintain tight tolerances while reducing assembly complexity through consolidated part designs. Its high strength-to-weight ratio keeps consolidated parts light, and printing near-net shapes avoids the material waste of machining parts from bulk PEKK.
Our documented quality system provides full traceability from raw material through finished part.

- Instrument mounts and brackets
- Housings for vacuum environments
Automotive
Under-Hood & Engine-Bay Parts
Automotive teams use Antero 800NA for sensor housings, fluid reservoirs, heat shields and brackets in the engine bay, where heat and fluids combine. Flat-printed parts hold their shape to 157 °C under a 1.82 MPa load, and upright parts keep 82% of their room-temperature strength at 104 °C. It is designed for under-hood and engine-compartment parts.

Mechanical performance
Mechanical properties
Antero 800NA PEKK delivers dependable strength and stiffness for aircraft ducting, structural brackets and spacecraft housings, helping teams move from prototype to production with confidence. Its compressive strength is almost identical in both build directions, so it carries clamping and bearing loads well in any orientation.
FDM parts are strongest along the build plane. XZ values describe parts printed on edge and ZX values parts printed upright, so orient the main load path along the layers. Printed on edge, Antero bends without breaking in flexural testing, while upright parts are slightly stiffer in tension but far less ductile.

Material makeup
Physical properties
Antero is light for a high-performance polymer. Most of the little mass it loses in vacuum outgassing tests is absorbed water, which it regains in air.
After 1,000 hours of accelerated UV exposure, upright parts kept their full strength at break, so the material holds up on exposed hardware.

Heat performance
Thermal properties
Antero 800NA is a semi-crystalline PEKK. Its heat deflection temperature sits at its glass transition and barely changes between light and heavy loads or between flat and upright parts, so treat the glass transition as the practical ceiling for loaded parts. Stratasys also tested upright parts from well below freezing to above 130 °C; they are stronger in the cold and keep most of their strength when hot, which helps size engine-bay and space hardware that cycles through both.
Thermal expansion is listed by build direction; use the matching value when sizing clearances against metal parts.

Compatibility data
Chemical properties
Stratasys immersed Antero test parts printed on a Fortus 450mc for 168 hours to ASTM D543 and measured the change in tensile properties. Acids, bases and Skydrol 500B-4 hydraulic fluid had little effect on strength. Jet A and solvents such as toluene, MEK and ethyl acetate weakened parts printed on edge by up to a fifth and upright parts by less, and Stratasys describes resistance to these aviation fuels, fluids and solvents as good to excellent before annealing. Only dichloromethane attacks parts as printed; with that exception, tensile modulus changed by 10% or less for every reagent.
Annealing at 200 °C for three hours raises resistance further: annealed parts held up in dichloromethane, which swells and weakens parts as printed. Under strain, annealing makes upright parts more brittle, so it suits unloaded, solvent-exposed parts best. Chemical ratings are screening guidance; confirm them with application-specific testing before production release.

- Antero 800NA PEKK offers the highest chemical resistance available in FDM, with strong resistance to jet fuel, Skydrol hydraulic fluid, acids and bases, along with ultra-low outgassing (0.347% TML and 0.004% CVCM to ASTM E595) and a heat deflection temperature of 158 °C at 0.45 MPa, making it suitable for aerospace and space applications.
- Antero 800NA PEKK is printed by FDM on a high-temperature Stratasys F900, which extrudes it layer by layer at 0.254 mm and builds parts up to 914 × 610 × 914 mm. Teams use it for aircraft ducting and structural parts exposed to aviation fluids, and for spacecraft housings and other low-outgassing space hardware.
- Antero 800NA PEKK serves aerospace, space and satellite, oil and gas, chemical processing, automotive and defense programs. Typical parts include aircraft ducting and brackets, spacecraft housings and instrument mounts, pump housings and valve components, under-hood sensor housings and fluid reservoirs, and high-temperature tooling exposed to cutting fluids.
- Antero 800NA PEKK resists jet fuel, hydraulic fluids and industrial solvents, outgasses very little in vacuum and offers a high strength-to-weight ratio as a lighter alternative to metal components. Printed flat, it holds its shape up to 157 °C under a 1.82 MPa load, printing avoids the waste of machining bulk PEKK, and it meets FAR 25.853 burn and heat-release requirements in Stratasys testing.
- Antero 800NA PEKK costs more than standard FDM thermoplastics and runs only on high-temperature FDM systems (the Stratasys F900 and Fortus 450mc). It prints in natural colour only and needs SUP8000B breakaway support. The filament is moisture sensitive and needs proper storage and drying, and its high processing temperatures mean longer build times. Parts as printed are attacked by dichloromethane, annealing for maximum chemical resistance makes upright parts more brittle under strain, and upright parts stretch only 2.3% before breaking.
- Yes. In Stratasys testing, Antero 800NA PEKK meets the FAR 25.853 12-second and 60-second vertical burn, 15-second horizontal burn and heat-release requirements, as well as the Boeing BSS 7238 / 7239 and Airbus AITM 2.0007B / 3.0005 smoke density and toxic gas tests. Airworthiness approval of each part stays with the aircraft design approval holder.
