The latest in Fused Deposition Modeling (FDM) materials offers expanded opportunities for plastic 3D printed production parts in a key area – chemical resistance. Most thermoplastics fail when in contact with fuel, hydraulic fluids or other chemicals. FDM Antero™ 800NA, a Stratasys PEKK proprietary blend, solves those challenges with excellent mechanical properties and the highest chemical resistance available.
Standard PEKK is somewhat limited due to stock shapes and sizes in CNC machining, leading to limited design options and lengthy production times. Now, designers and engineers can take advantage of the advanced properties of PEKK with the design freedom and fast production times of 3D printing.
FDM Antero 800NA is ideal for customized parts needed at low volumes. The material is perfect for quick delivery of parts to market, especially when there is uncertainty of demand, product lifespan, or when the design is in the early stages, and changes are needed.
Antero 800NA is strong with excellent temperature, wear and chemical resistance. The material has ultra-low outgassing properties with TML (total mass loss) of 0.27% and a CVCM (collected volatile condensable materials) of 0.01%. This data exceeds the NASA specifications for selecting spacecraft materials with low outgassing properties.
The additive PEKK material has the highest chemical resistance available with FDM technology, expanding its use in aircrafts and oil and gas applications that other materials can’t fulfill. Antero 800NA passes 14CFR/FAR 25.853 in (horizontal 15 sec, vertical 12 & 60 sec, 45° ignition and heat release), and it passes the NBS smoke density both flame and non-flame per 4814/E662. Antero 800NA has passed MIL-STD-810G-504.1, the military standard that tests the limits to the conditions that the part will experience in service life, specifically the contamination by fluids.
3D printing with the PEKK blend provides new design freedom than standard PEKK which would be CNC machined. The material and stock shapes tend to be expensive, and so much of the material is milled away and discarded. 3D printing only utilizes the material needed for the geometry. Moreover, an engineer or development team only has to maintain digital inventories with the ability to quickly 3D print their components as needed.
FDM Antero 800NA produces extremely accurate parts even in large sizes, with a standard offered tolerance of +/-0.010” or +/-0.0015 per inch, whichever is greater. When there are critical, tighter dimensions that are needed, Stratasys Direct's engineering staff and quality departments can review projects and give confidence to the customer prior to ordering.

Due to Antero 800NA’s enhanced mechanical properties, the material can withstand exposure to cleaning chemicals, fuels, hydraulic fluids and high temperatures experienced in aerospace environments. The material can be used in aerospace applications such as clips, brackets, ducting, tooling, space vehicle components, ground support equipment, and test and flight operations.
Further applications include components in high-end manufacturing that may be exposed to chemicals and high temperatures, custom tooling, jigs, fixtures, custom housings for oil and gas components, under-hood and fuel components, and any parts exposed to hydrocarbons.
