PEI (FDM, Stratasys ULTEM 1010 resin)

PEI printed by fused deposition modeling in Stratasys ULTEM 1010 resin is an unfilled polyetherimide filament grade for high-temperature material extrusion systems. The amorphous polymer is printed from dried filament with a hot nozzle and a heated build chamber, and parts show visible layer lines and are weakest across layers, where strength depends on interlayer bonding. Overhangs need removable supports, and cooling stresses can warp large or thin sections. Printed parts serve as high-temperature tooling such as composite layup tools, as jigs and fixtures, and as functional parts exposed to heat and chemicals. Every value on this page is read from Stratasys' own material data sheet — quoted, cited and dated — and is the maker's statement about printed material, not a measurement by MatWorld; none has yet been reviewed by a person.
