3DXTech ThermaX™ PEEK High-Temperature Industrial PEEK Filament
High-Temperature Industrial PEEK Filament
ThermaX™ PEEK is a high-performance PAEK-family polymer that delivers continuous-use capability to 240–260°C, inherent flame resistance, and broad chemical inertness for applications where failure is not an option.
Lead time varies. Contact Rev1 to confirm availability.
WHY PEEK
Engineering Properties in a Class of Their Own
ThermaX™ PEEK is a PAEK-family ultra-polymer that combines four performance pillars no lower-temperature polymer can match simultaneously. It is the go-to material for aerospace, medical, and industrial applications where structural and thermal demands eliminate all commodity options.
PAEK-Class Heat Resistance
Continuous use to 240–260°C with a 343°C melting point. Maintains structural integrity where PA, PC, and even ULTEM-family materials have long since softened.
Broad Chemical Inertness
Resists hydrocarbons, automotive fluids, alcohols, and aggressive chemical solutions across a wide temperature range. Suitable for fluid-contact components in demanding process environments.
Inherent Flame Resistance
Self-extinguishing with low smoke and minimal toxic gas emission. No flame-retardant additives required — the polymer chemistry itself meets demanding fire-safety criteria.
Metal-Replacement Strength
High tensile strength and stiffness retained at elevated temperature, with a strength-to-weight advantage over aluminum for many load-bearing bracket and fixture applications.
PRINTING WITH PEEK
PEEK Demands an Industrial Hot End
ThermaX™ PEEK is not a plug-and-print material. It requires purpose-built hardware and strict process discipline.
- Extruder Temp 375–410°C — all-metal hot end required
- Bed Temp 130–145°C — PEI or high-temp build surface
- Chamber Temp 70–140°C — actively heated enclosure strongly recommended
- Nozzle Hardened steel or ruby tip — ≥0.4mm diameter
- Drying 120°C / 4 hr minimum before every print session
- ⚠ End-of-Session Purge nozzle completely before cooling. Residual PEEK carbonizes at temperature and causes severe clogs.
THERMAL DATA
Where the Temperature Scale Ends for Other Polymers, PEEK Begins
Four thermal milestones that define ThermaX™ PEEK’s operating envelope — verified against 3DXTech Technical Data Sheet Rev. 3.
Onset of chain mobility. Semi-crystalline PEEK maintains dimensional stability well above this point in load-bearing applications.
Sustained structural load-bearing at temperatures that reduce PA, PC, and ULTEM to deformed geometry.
Semi-crystalline melt transition. The wide gap between Tg and Tm gives PEEK an unusually stable processing window.
Required before every session. Low moisture absorption (<0.5%) but even trace moisture degrades print quality at these temperatures.
CHEMICAL RESISTANCE
Inert to the Environments That Destroy Other Polymers
ThermaX™ PEEK’s semi-crystalline structure provides a dense molecular barrier against chemical attack that would degrade PA, PC, or ABS within hours.
Consult TDS for complete chemical compatibility data before use in fluid-contact applications.

WHERE IT WORKS
Six Industries Where PEEK Is the Default Answer
When weight matters, temperatures are extreme, chemicals are aggressive, or fire codes are strict — ThermaX™ PEEK 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.
PEEK has low inherent moisture absorption, but printing with undried filament at these temperatures produces defective output. Follow this protocol every session.
Dry Before Every Session
120°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™ PEEK vs. Commonly Evaluated Alternatives
Buyers evaluating ultra-polymer filament for demanding applications typically compare three categories: a platform-tied industrial benchmark, a resin-manufacturer direct peer, and an adjacent flame-retardant CF option for buyers weighing multiple performance axes simultaneously.

FREQUENTLY ASKED
ThermaX™ PEEK — Buyer Questions Answered
What nozzle and bed temperature does ThermaX™ PEEK require?
ThermaX™ PEEK requires an extruder temperature of 375–410°C and a bed temperature of 130–145°C. A fully enclosed, actively heated chamber at 70–140°C is strongly recommended to prevent delamination and warping. PEEK demands an industrial-grade all-metal hot end — standard consumer hot ends are not rated for these temperatures.
Do I need a hardened steel nozzle to print ThermaX™ PEEK?
Yes. ThermaX™ PEEK requires a hardened steel or abrasion-resistant nozzle of at least 0.4mm diameter. Standard brass nozzles will degrade quickly at PEEK printing temperatures. Ruby-tipped or tungsten carbide nozzles are alternatives for extended print runs. Important: purge the nozzle completely before cooling — residual PEEK carbonizes and causes severe clogs.
What spool sizes are available for ThermaX™ PEEK, and is there a minimum order?
ThermaX™ PEEK is available in 250g ($158), 500g ($298), 1kg (contact Rev1 for pricing), and 2kg (special order — minimum 10 units, contact Rev1). The 500g spool is compatible with Bambu AMS, Creality CFS, and Anycubic ACE Pro multi-material management systems.
How should ThermaX™ PEEK be stored and dried before printing?
PEEK has low moisture absorption (under 0.5%), but for best results dry at 120°C for at least 4 hours before each print session. Store in an airtight container with desiccant between uses. Moisture-affected PEEK produces rough surface finish, weakened layer adhesion, and increased stringing.
Is ThermaX™ PEEK biocompatible or suitable for medical applications?
PEEK chemistry is well-established in medical devices including spinal implants, dental prosthetics, and surgical instrumentation, and is used in ISO 10993-compliant components. Whether a specific printed part meets applicable regulatory requirements depends on the lot, post-processing, and intended use. Consult the 3DXTech Technical Data Sheet and your regulatory affairs team for compliance verification.
Which 3D printers are compatible with ThermaX™ PEEK filament?
Any 3D printer with an all-metal hot end rated to at least 400°C, a heated bed capable of 130–145°C, and a heated enclosure at 70–140°C can process ThermaX™ PEEK. The CreatBot F160-PEEK, CreatBot PEEK-300, and CreatBot F430 are validated industrial platforms. The 500g spool is also compatible with Bambu AMS, Creality CFS, and Anycubic ACE Pro systems that support high-temp materials.
How does ThermaX™ PEEK compare to Stratasys Antero 800NA for aerospace applications?
Antero 800NA uses PEKK-A chemistry and prints at a lower extrusion temperature (~350–370°C), and is designed for Stratasys-platform workflows. ThermaX™ PEEK provides a significantly higher continuous-use temperature ceiling (240–260°C vs. ~150°C for Antero 800NA), making it more suitable for sustained high-heat environments. Buyers should evaluate based on thermal requirements, existing printer infrastructure, and applicable certification standards.
How does 3DXTech ThermaX™ PEEK compare to Victrex-branded PEEK filament?
Victrex is a primary manufacturer of PEEK polymer resin. 3DXTech is a filament fabricator using high-quality PEEK feedstock to produce ThermaX™ PEEK. Both are PEEK — the same PAEK polymer family. ThermaX™ PEEK is available through authorized resellers like Rev1 Tech with competitive pricing and standard spool sizes, providing an accessible open-platform route without requiring a direct OEM relationship.
