iMakr's Verdict
PEI (Polyetherimide) has a maximum operating temperature of 170°C and one of the highest tensile strengths of all 3D printing filaments. This inherently flame retardant plastic has UL94 VO and 5VA ratings. It is used in a range of mechanical industries for producing dies, moulds, tooling, patterns, structural parts. The 3D4Makers PEI filament is made using Ultem 1010. It does not come into contact with water during production and as a result has a very low moisture content.
