PPA: common questions
What is PPA good for?
PPA is a common choice for under-hood automotive, chemical processing, high-temp industrial. High-performance semi-aromatic nylon with superior heat and chemical resistance.
How strong and heat-resistant is PPA?
Printed PPA parts have a typical tensile strength of 80–100 MPa and heat resistance of ~160 °C. These are typical values for printed parts in the XY direction; strength between layers is lower, so orientation matters for loaded parts.
How big a part can you print in PPA, and how fast?
Up to 350 × 320 × 325 mm in one piece; larger parts are printed in sections and joined, after a review. Production takes 2-5 business days, and rush service is available.
