Sometimes known as “Ultem 1010”, PEI is most commonly found in 3D printing as the de-facto bed material of choice. For those with machines strong enough to meet the printing requirements, PEI is also a viable filament to print. This amorphous polymer needs no post-processing and provides ready-to-go parts right off of the print sheet.

• High strength
• Well-known color and name (cool-factor)
• No post-processing required (amorphous)

• Cost, availability
• High temperature requirements

No experience has been gathered on additives for this filament.

Lower temperatures can be made to work but will pit you in a battle against incredibly strong warping from the plastic, both with overall part design as well as from the part warping from the bed.

These numbers are provided as a baseline, and need adjustment and calibration for your specific printer/filament/color combination.
