Ultem 1000 (PEI) is an amorphous, amber-to-transparent thermoplastic with characteristics similar to the related plastic PEEK. Relative to PEEK, PEI is cheaper, but is lower in impact strength and usable temperature. PEI is suitable for contact with foods, that exhibits high mechanical strength and rigidity. The characteristic profile includes very good hydrolysis resistance, and dimensional stability, combined with a relatively high long term service temperature. And because of its adhesive properties and chemical stability it became a popular bed material for FDM 3D printers.
