Epolymer 3d Print Filament PEI

Epolymer 3d Print Filament PEI
Benefits of ULTEM 1010 PEI Include:
High thermal properties, with a Tg of 217°C
Inherently flame-resistant
Long-term hydrolytic stability
Excellent dimensional stability, low heat creep sensitivity, and a very low, uniform coefficient of thermal expansion create highly reproducible part-to-part dimensions
Exceptional strength and modulus, even at elevated temperatures
Good resistance to a broad range of chemicals, include automotive fluids, fully halogenated hydrocarbons, alcohols, and aqueous solutions
Stable dielectric constant and dissipation factor over a wide range of temperatures and frequencies
ULTEM, Polyetherimide PEI is an amorphous, amber-to-transparent thermoplastic with characteristics similar to the related plastic PEEK. Relative to PEEK, PEI is cheaper, but is lower in impact strength and usable temperature.
3d Print Filament PEI has a very high temperature stability, even for non-reinforced PEI. It has good toughness and strength. Therefore, the superior thermal stability of PEI can be used to fabricate high temperature heat resistant devices.
With excellent mechanical properties, electrical insulation properties, radiation resistance, high temperature resistance and wear resistance, and through the microwave, PEI also has good flame retardancy, chemical resistance and electrical insulation properties.
It can be used for a long time at an operating temperature of 160 to 180°C.
3d Print Filament PEI
Recommended Print Settings:
Extruder: 370-390°C
Bed Temp: 120-160°C
Other: No cooling fan with print speeds of 20mm/s as a starting point
Heated Chamber: Recommended, a chamber helps reduce warping and improves layer adhesion
Drying Instructions: 150°C for 4 hours.
Annealing 3D Printed Parts:
If needed, parts printed using ULTEM™ may be annealed in a hot-air oven to reduce any printed-in stresses which may be present in the part. Printed-in stresses may occur in any plastic and may result in lower than expected mechanical properties. If this is an issue with your part, you can follow the simple 5-step ramp up/down process for annealing the ULTEM™ parts.

Step 1: Place printed parts in cool, room-temp oven.
Step 2. Set temp to 300°F and allow to stabilize for 1 hour.
Step 3: After 1 hour at 300°F, increase oven temp to 400°F and allow to stabilize 1 additional hour.
Step 4: After 1 hour at 400°F, reduce heat back to 300°F and allow to stabilize for 30 minutes.
Step 5: After 30 minutes, turn off oven heat and allow printed parts to return to room temp inside the oven as it cools.
