Kepstan® PEKK Resins
for 3D Printing
The tunable crystallinity of Kepstan® PEKK allows it to be printed by the SLS process, or FFF (in both amorphous and semi-crystalline forms).
FFF Printing of Kepstan® PEKK
Semicrystalline
-
All the properties of amorphous Kepstan® PEKK plus
-
Slightly higher stiffness
-
Higher use temperature
-
Extreme chemical resistance
-
Requires post processing or high build temperature environment
-
The most robust way to make semicrystalline PAEK parts by FFF
-
Limited geometry and dimensional tolerance
-
Consult or website for further advice
Amorphous
-
Excellent layer adhesion, great strength, toughness, ductility
-
Low warping, accessible print window
-
Very good chemical resistance -> superior to PEI, PPSU
-
Low flammability
-
Moderately high use temperature
-
Easy to process
SLS Printing of Kepstan® PEKK
- The same slow and tunable crystallization rate makes PEKK the ideal PAEK for SLS
- Slow crystallization rate enables stress relief during crystallization, low melting point enables reasonable processing temperatures
- Unconstrained design, maximum performance

Outstanding Chemical Resistance
- Samples were tested per ASTM D543.
- 1 week of immersion at 23°C
- Crystalline Kepstan® PEKK enables the best chemical resistance.
- Amorphous Kepstan® PEKK also shows much better resistance versus PEI or PPSU.
Applications
Air Ducts for Transportation
- Kepstan® PEKK meets the demanding requirements of industries such as aviation and transportation
- 3D printing allows complex air ducts to be printed in one piece, saving time and money in production
Brackets for Aerospace
- Kepstan® PEKK provides the mechanical strength, temperature resistance, and chemical resistance demanded by the aerospace industry
- Specialized and complex brackets can be rapidly 3D printed, reducing inventory and saving cost
