PEEK: 1.75mm

from 99.00

“It just behaves really well being printed very quickly even without a headed chamber.  Prints predictably and the consistency is really, really good.  I like it better than 3DXTech.”

- Vision Miner

PEEK (polyetheretherketone) is a high-performance engineering thermoplastic with excellent mechanical and chemical resistance properties that are retained to high temperatures. PEEK has outstanding resistance to harsh chemicals, and excellent mechanical strength and dimensional stability. It offers hydrolysis resistance to steam, water, and sea water.

3D Printlife’s PEEK is extruded in the USA at our ISO Class 8 Cleanroom capable medical grade extrusion facility, and maintains a dimensional accuracy better than +/- 0.05mm.

Our lead engineers have over 40 years of experience in specialty extrusion of high-performance thermoplastic polymers like PEEK and Ultem, and every inch of our engineering grade filaments are extruded under their expert supervision.

  • Medical: Considered an advanced biomaterial used in medical implants.

  • Aerospace: Utilized in both commercial and military aircraft, and in both settings, only reliable, durable materials are utilized.

  • Semiconductors and electronics: PEEK’s ability to retain its strength at high temperatures, its purity as well as its ability to withstand harsh chemicals makes it a natural fit for semiconductor and electronics manufacturing

  • Tensile Strength: 98 MPa

  • Felxural Modulus: 3.6 GPa

  • Glass transition temperature: 143 °C

  • Inherent flame resistance (UL94 V-0)

  • Extrusion Temp: 370°C to 450°C

  • Available to order in custom weights starting at 100g to allow for introductory testing.

Recommended Settings

Drying: In many cases PEEK should be dried out in an over prior to printing as drying will improve print performance.  For best results we recommend 3 hours of drying at 150°C

Nozzle Temperature: Your printing temperature should be around 360°C - 410°C, but this is dependent on your printer. 

Print Bed: Set to 120°C at minimum and we recommend 130 - 145°C

Print Surface: For your build platform material we recommend using PEI sheets.

Thermal Control of Build Chamber: Enclosure temp (if your printer is equipped):  70 - 140°C [hotter is better, up to 140°C]

Print Speed:  10-50 mm/s for 0.2mm layer height, fast as results dictate.
