Collection: PEEK & High-Temp Filament

Ultra-High-Temperature Engineering. The Top of the Materials Pyramid.

PEEK, PEI (Ultem), and PPS-CF represent the highest tier of FDM-printable materials — used in aerospace structural components, medical device housings, chemical processing equipment, and high-temperature industrial tooling. These materials require machines with actively heated enclosures, all-metal hotends capable of 400°C+, and print temperatures that exceed anything standard printers can reach.

If you're printing these materials, you already know what you need. These are the filaments for it.

What you'll find here:

  • ThermaX PEEK (3DXTech) — 500g, Made in USA
  • ThermaX PEI Ultem 1010 (3DXTech) — 500g, Made in USA
  • Push Plastic PEI 1010 — 1.75mm and 2.85mm, 3kg bulk
  • Push Plastic PEI 9085 — 2.85mm, 3kg bulk
  • Ambrosia PPS-CF — 1kg, high-temperature polyphenylene sulfide CF
  • Polymaker Fiberon PPS-CF10 — 500g

Note: PEEK and PEI require specialized machines with enclosures capable of 120°C+, hotends rated above 400°C, and engineering-grade print surfaces. Not suitable for standard FDM printers.
