USA-made PEEK, with a real datasheet behind it.
3DXTech compounds ThermaX PEEK in the USA with published mechanical, thermal, and chemical data — no mystery PEEK. Rev1 Technologies is your authorized 3DXTech reseller and US support partner, Auburn Hills, Michigan.
One of the highest-performance polymers ever invented.
PEEK (PolyEtherEtherKetone) sits at the very top of the engineering-polymer pyramid: it combines exceptional mechanical strength, an extremely high service temperature, and broad chemical and hydrolysis resistance that lets printed parts survive environments that melt or dissolve ordinary plastics. 3DXTech compounds ThermaX PEEK in the USA to printable, consistent filament so you can produce real PEEK parts — brackets, manifolds, seals, fixtures, and end-use components — on a high-temperature 3D printer instead of machining them from billet.
Print end-use parts that survive heat, chemicals, and load.
The same polymer used in aerospace, medical, and oil-and-gas hardware — now from a spool.
PEEK holds its strength and stiffness at temperatures where most thermoplastics have long since softened, resists a wide range of solvents and fuels, and is inherently flame retardant with low smoke. That combination makes it a go-to for under-hood automotive, downhole tools, sterilizable medical fixtures, and semiconductor handling where contamination and outgassing matter.
Numbers that put it above ABS, PC, and nylon.
All figures from the 3DXTech ThermaX PEEK technical data sheet — see the full TDS for test methods and the complete property table.
Long-term use temperature far beyond engineering plastics like PC or nylon, with a glass transition near 143°C.
High strength and stiffness that hold up under sustained mechanical load and repeated cycling.
Low smoke and low toxicity combustion without added halogenated flame retardants.
Resists most solvents, fuels, and hydrolysis — survives autoclave and aggressive cleaning.
It needs a real high-temp printer — here's what.
PEEK is demanding: it prints hot, needs an actively heated chamber to crystallize and avoid warping, and must be dried before use. Match these and the results are repeatable.
An all-metal 400°C+ hotend is required; a hardened/abrasion-resistant nozzle helps with filled grades.
High bed temperature plus a suitable adhesive for first-layer grip on a large, hot part.
An actively heated chamber is essential for crystallization, layer bonding, and dimensional stability.
Dry the filament before printing and keep it dry — PEEK picks up moisture that ruins surface quality.
The industries that print PEEK.
From a 250 g trial spool to a 2 kg production reel.
Buy a small spool to qualify, then scale to a 2 kg reel.
Choose your reel size in the buy-box — price scales with the spool.
PEEK is a premium material, so start with a 250 g or 500 g spool to dial in your profile and validate the part, then move up to 1 kg or 2 kg reels for production runs. Smaller reels also fit popular automated material systems. Pick the size above and add it to your cart, or ask us about case pricing.

FAQ
3DXTech ThermaX PEEK — Common Questions
What printer do I need for PEEK?
A true high-temperature printer: an all-metal 400°C+ hotend, a 130–160°C bed, and an actively heated chamber (90–120°C). The heated chamber is essential for crystallization and dimensional stability — PEEK will warp and delaminate without it.
Do I have to dry it?
Yes. PEEK absorbs moisture that causes poor surface finish and weak layers. Dry the filament before printing and keep it in a dry box during long prints.
Which reel size should I buy?
Start with a 250 g or 500 g spool to validate your profile and the part, then scale to 1 kg or 2 kg for production. Pick the reel size in the buy-box; price scales with the spool.
How does PEEK compare to PEI/ULTEM or PEKK?
PEEK offers among the highest continuous-use temperature (~250°C) plus excellent chemical resistance and strength. PEI/ULTEM is FST-rated and lower cost but lower temperature; PEKK offers tunable crystallinity. We'll help you choose.
Is it made in the USA?
Yes — 3DXTech compounds ThermaX PEEK in the USA with a published technical data sheet and lot traceability.
Can Rev1 help qualify PEEK for my application?
Yes. Tell us the temperature, chemistry, and loads and our materials team confirms fit, suggests print settings, and can quote case or standing-order pricing. Call (248) 707-2950.
