Tropical sunset beach and sky background as exotic summer landscape PEI 1010 Filament 1.75mm 3kg. Introducing the ultimate engineering thermoplastic: PEI or Polyetherimide made from Sabic Innovative Plastic's ULTEM 1010 and 9085 resin. Featuring unmatched strength, thermal stability, and bio compatibility. ***These are very high temperature filaments that will require an enclosure and high temps on both the nozzle and bed *** PEI 1010: Excellent thermal properties with a Tg (glass transition) ~215C Exceptional strength, dimensional stability, and inherent flame retardant Good chemical resistance to wide range of chemicals Ideal for demanding Electrical Automotive Aerospace applications Recommended Print Settings for PEI 1010: Extruder: 375C Bed: 160C + (the hotter the better) Bed Prep: PC or PEI sheet Print speed 30mm s PEI 9085: Similar to PEI 1010 with slightly lower melt temperature making printing easier Great thermal properties with a Tg (glass transition) ~185C Great chemical resistance, strength, dimensional stability, and flame retardant Ideal for Electrical Automotive Aerospace applications Recommended Print Settings for PEI 9085: Extruder: 350C Bed: 150C + (the hotter the better) Bed Prep: PC or PEI sheet Print speed 30mm s ULTEM is a registered trademark of Sabic Innovative Plastics. Push Plastic manufactures our PEI filament using materials sourced from SABIC or SABIC approved vendors.
