WHY PEI 1010
217°C Tg. Inherent V-0. FDA-Compliant ULTEM 1010 Resin.
ThermaX™ PEI 1010 is 3DXTech’s custom-formulated polyetherimide filament using Sabic ULTEM 1010 resin. It delivers the highest Tg of any 3DXTech unfilled filament with inherent UL 94 V-0 flame resistance and FDA-compliant base resin for food-contact and medical sterilization environments.
Highest Tg in Class
217°C glass transition — highest of any 3DXTech unfilled filament. Maintains structural integrity where PEEK softens.
Inherent UL 94 V-0
Flame resistance is built into the PEI polymer backbone — no additives, no long-term degradation of flame performance.
Broad Chemical Resistance
Resists automotive fluids, hydrocarbons, alcohols, and aqueous solutions. ULTEM 1010 resin is FDA-compliant for food contact.
Made in USA
Produced in-house at 3DXTech’s Grand Rapids, MI facility under ISO 9001:2015 certification. Lot traceability and process controls throughout.
PRINTING WITH PEI 1010
PEI 1010 — The Highest-Tg Unfilled Filament
ThermaX™ PEI 1010 is not a plug-and-print material. It requires industrial hardware and process discipline — a heated chamber and all-metal hot end rated to 400°C+. Follow this protocol for consistent results.
- Extruder Temp 370–390°C — all-metal hot end required
- Bed Temp 120–160°C — PEI or garolite build surface
- Chamber Temp ≥70°C recommended — actively heated enclosure strongly recommended
- Nozzle All-metal, stainless or hardened steel — ≥0.4mm diameter
- Drying 150°C / 4 hr minimum before every print session
- ⚠ End-of-Session Purge nozzle completely before cooling. Residual PEI 1010 can carbonize in the melt zone if left to cool — always purge fully before shutdown.
THERMAL DATA
Where the Temperature Scale Ends for Other Polymers, PEI 1010 Begins
Four thermal milestones that define ThermaX™ PEI 1010’s operating envelope — verified against 3DXTech ThermaX PEI 1010 Technical Data Sheet v4.
Highest Tg of any 3DXTech unfilled filament. PEI 1010 stays fully rigid where PEEK (143°C Tg) and PEI 9085 (186°C Tg) have already softened.
HDT at 0.45 MPa. Structural load-bearing capability well above autoclave sterilization temperatures, making PEI 1010 suitable for reusable medical instrument housings.
Sustained continuous-use temperature under structural load. For short-term peak exposure, the 213°C HDT and 217°C Tg define the practical upper ceiling.
Required before every session. PEI is hygroscopic — even trace moisture causes bubble defects and weakened layer adhesion at 370–390°C extrusion temps. Print from the dryer.
CHEMICAL RESISTANCE
Inert to the Environments That Destroy Other Polymers
ThermaX™ PEI 1010’s amorphous PEI backbone resists a broad range of chemicals that would degrade PA, PC, or ABS within hours — including automotive fluids, hydrocarbons, alcohols, and aqueous solutions.
Consult TDS for complete chemical compatibility data before use in fluid-contact applications.

PRINT QUALITY
Production-Grade Output on the Right Equipment
ThermaX™ PEI 1010 produces parts with fine surface detail and strong interlayer adhesion when printed on a properly configured industrial platform — with a more forgiving process window than standard PEEK.
COMPATIBLE PLATFORMS

WHERE IT WORKS
Six Industries Where PEI 1010 Is the Answer
When weight matters, temperatures are extreme, chemicals are aggressive, or fire codes are strict — ThermaX™ PEI 1010 belongs in the design.
Aerospace
Structural brackets, ducting, turbine-adjacent components, and radome housings requiring flame resistance, low outgassing, and temperature endurance.
Medical Devices
Surgical instruments, implant trial components, autoclavable fixture tooling, and patient-specific guides where PEEK chemistry is the established biocompatible standard.
Automotive Under-Hood
Valve seats, fluid handling brackets, sensor housings, and sealing components exposed to sustained heat and hydrocarbon chemical attack.
Chemical Processing
Pump housings, impeller components, valve bodies, and manifolds in contact with aggressive chemical process streams at elevated operating temperature.
Semiconductor
Wafer-handling end effectors, high-temperature test fixtures, and process chamber components requiring dimensional stability under thermal cycling.
Industrial Tooling
Jigs, bearing cages, wear-contact fixtures, and press-fit tooling demanding stiffness and thermal ceiling that engineering nylons cannot sustain.
MATERIAL CARE
Moisture Is the Enemy. A Proper Protocol Eliminates It.
PEI is hygroscopic and absorbs moisture readily. Printing with undried filament at 370–390°C produces bubbling, rough surfaces, and weakened layer adhesion. Follow this protocol every session.
Dry Before Every Session
150°C minimum / 4 hours minimum. No exceptions — even a sealed spool that has been open for a few days benefits from a fresh drying cycle.
Print From the Dryer
For best results, print directly from a heated dry-box or dryer system. Ambient humidity will re-absorb into the filament during extended print runs.
Store Sealed With Desiccant
Return unused filament to an airtight bag or container with fresh desiccant immediately after printing. Long-term storage in original sealed packaging is acceptable.
Recognize Wet Filament Symptoms
Popping or crackling during extrusion, rough surface texture, reduced layer adhesion, and visible bubbling in the melt are signs of moisture contamination. Re-dry and restart.
HOW IT COMPARES
ThermaX™ PEI 1010 vs. Commonly Evaluated Alternatives
Buyers evaluating PEI 1010 typically compare against the platform-tied Stratasys ULTEM 1010 benchmark using the same base resin, ThermaX PEI 9085 for FAA-qualified applications, and ThermaX PEEK for buyers choosing between high-Tg amorphous PEI and semi-crystalline PEEK.

FREQUENTLY ASKED
ThermaX™ PEI 1010 — Buyer Questions Answered
What is ThermaX PEI 1010?
ThermaX PEI 1010 is 3DXTech’s custom-formulated polyetherimide filament using Sabic ULTEM 1010 resin — the food-contact and medical-grade variant of the PEI family. It delivers a 217°C Tg and inherent UL 94 V-0 flame resistance without additives.
What temperatures does ThermaX PEI 1010 require?
Extruder: 370–390°C with an all-metal hotend. Bed: 120–160°C on PEI or garolite. Heated chamber (≥70°C) is strongly recommended. Dry at 150°C for 4 hours before printing.
Does PEI 1010 require a hardened steel nozzle?
No. ThermaX PEI 1010 is unfilled, so abrasion is not a concern. However, an all-metal nozzle rated for 400°C+ is recommended. Standard brass nozzles may soften at extended 390°C operation — stainless or hardened steel is an inexpensive upgrade worth making.
What is the difference between PEI 1010 and PEI 9085?
PEI 1010 (ULTEM 1010) has a higher Tg (217°C vs 186°C) and is FDA-compliant for food and medical contact. PEI 9085 (ULTEM 9085) was originally qualified for FAA flammability and smoke/toxicity standards. Choose 1010 for autoclavability or FDA food contact; choose 9085 if your application specification requires it.
Is ThermaX PEI 1010 autoclavable?
Yes. ULTEM 1010 resin is rated for steam autoclave sterilization at 134°C, making it one of the few FFF filaments suitable for reusable medical instrument housings and surgical guide fixtures. The 217°C Tg ensures the part stays fully rigid well above autoclave temperatures.
Why is PEI 1010 flame resistant without additives?
The imide linkage in the PEI polymer backbone inherently limits combustion. No brominated or phosphorus-based flame retardants are required — the UL 94 V-0 rating is intrinsic to the polymer itself and persists for the life of the part.
How does ThermaX PEI 1010 compare to Stratasys FDM ULTEM 1010?
Both use Sabic ULTEM 1010 resin. Stratasys FDM ULTEM 1010 is platform-locked to Fortus/F900 systems with soluble support at significantly higher cost of ownership. ThermaX PEI 1010 runs on any open-material machine capable of 380–390°C with a heated chamber — the same base chemistry at a fraction of the system cost.
Should I choose PEI 1010 or ThermaX PEEK?
Choose PEI 1010 for: higher Tg (217°C vs 143°C), inherent UL 94 V-0 compliance, FDA/medical autoclave capability, or lower entry cost ($70 vs $175 per 250g). Choose PEEK for maximum mechanical stiffness and tensile strength — PEEK’s semi-crystalline structure gives it an edge in modulus and creep resistance at moderate temperatures.
