D3D ULTEM® PEI Filament, Natural, 1.75mm 500g

D3D's PEI filament is manufactured from genuine ULTEM® brand PEI resin. ULTEM® is an amorphous thermoplastic polyetherimide (PEI) material which combines exceptional mechanical, thermal, and electrical properties. Natural ULTEM® 1000 has a translucent amber color. ULTEM® has many applications in medical, electronic/electrical, microwave, automotive, and aircraft industries.

D3D's PEI Filament has:

• Excellent mechanical and high tensile strength at room temperature. It retains a significant portion of this strength at elevated temperatures.
• Outstanding heat resistance. Has a heat deflection temperature of 200°C, softening point of 218°C and retains its physical properties at elevated temperatures. It also has a flammability rating of V-0.
• Exceptional stress resistance to environmental forces.
• Inherent flame resistance (V-0) with low smoke evolution
• High mechanical strength. Exceptional tensile and flexing strength.
• High dielectric strength and stability, making it an excellent electrical insulator
• Low dissipation factor over a wide range of frequencies
• Good resistance to a broad range of chemicals
• Excellent machinability and finishing characteristics. Can be easily machined with conventional metalworking tools, painted, hot stamped, printed, or plated.

Temperature Recommendations 

• Printing Temp. : 300 C 
• Highly recommended to print this in a printer with an actively heated chamber.
• Bed temp 120°C +
• Print on PEI printing surface/tape/sheet.
• To improve printing performance PEI should be dried prior to printing.

The resin used in this natural grade is FDA, USP Class VI and NSF compliant.
