3DXTech ThermaX PEI 9085 Natural 500g

This filament is not suitable for the Prusa MK, XL and MINI series printers as the temperature needed to print this material is not attainable. Please check the printing setup if your printer is capable of printing this material.

ThermaX™ PEI 9085 is a premium filament made using ULTEM™ 9085 resin from Sabic. This resin is FAA-approved for FST applications (Flame/Smoke/Toxicity) and meets FAR 25.853 and OSU 65/65 standards.

Basic Attributes

• High thermal properties, with a Tg of 186°C
• Inherently flame-resistant with low smoke evolution and low smoke toxicity
• 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

Printing Setup

• Extruder: 350-380°C
• Bed Temp: 140-160°C
• Other: No cooling fan with print speeds of 16 mm/s as a starting point
• Heated Chamber: Recommended, a chamber helps reduce warping and improves layer adhesion
• Drying Instructions: 120°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.

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