thumb|PEI powder coating|powder-coated build plate on a [[Bambu Lab A1 mini FFF 3D printer]] Polyetherimide (PEI; branded as Ultem) is an amorphous, amber-to-transparent thermoplastic with characteristics similar to the related plastic PEEK. When comparing PEI to PEEK, the former is cheaper but has lower impact strength and a tighter temperature range.
