PEI filament for FDM 3D printing
Heat-resistant filament for special applications
PEI, also called polyetherimide, has very high heat resistance. Depending on the material, it can withstand temperatures over 200 ° C.
3D printing with PEI requires a high extrusion temperature. (350 - 370 ° C)
ULTEM, an offshoot of PEI, is highly resilient and resistant to many chemicals.
