mkulu makina katundu PEI- Osadzaza, GF, CF kwa mafakitale katundu chivundikirocho

Polyetherimide (PEI) ndi amorphous, amber-to-transparent thermoplastic yokhala ndi mawonekedwe ofanana ndi PEEK yapulasitiki. Poyerekeza ndi PEEK, PEI ndiyotsika mtengo, koma ndiyotsika mphamvu komanso kutentha koyenera. Chifukwa cha zomatira zake komanso kukhazikika kwamankhwala zidakhala chida chodziwika bwino cha bedi kwa osindikiza a FFF 3D.

Kutentha kwa galasi la PEI ndi 217 ° C (422 ° F). Kuchuluka kwake kwa amorphous pa 25 °C ndi 1.27 g/cm3(.046 lb/in³). Amakonda kupsinjika ndi kusweka kwa zosungunulira za chlorine. Polyetherimide imatha kukana kutentha kwambiri ndi mphamvu zamagetsi zokhazikika pama frequency osiyanasiyana. Izi zamphamvu kwambiri zimapereka kukana kwamankhwala kwabwino kwambiri komanso ma ductile omwe ali oyenera kugwiritsidwa ntchito mosiyanasiyana, ngakhale omwe akuphatikiza kukhudzana ndi nthunzi.
