Material comparison
A high-performance material with flame, smoke and toxicity (FST) compliance for aircraft interiors. One of the most heat-resistant FDM materials; food-contact and biocompatible certified grades available. So which one is right for your project? Compare the values, strengths and weaknesses side by side.
PEI (polyetherimide) / PC copolymer
ULTEM 9085 is a polyetherimide-based thermoplastic. It is known for its high strength-to-weight ratio and flame, smoke and toxicity behavior that meets aircraft interior standards (FAR 25.853). It is used in industrial FDM systems for aircraft ducts, cabin components and train interior parts.
PEI (polyetherimide)
ULTEM 1010 is pure polyetherimide. With its high heat and chemical resistance, steam sterilizability and food-contact / biocompatibility certified grades, it is used for composite layup tooling, medical instruments and food production tooling.
