3D Printlife - PEEK: 1.75mm

PEEK is a semicrystalline thermoplastic with excellent mechanical and chemical resistance properties that are retained to high temperatures.

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

  • 1.75mm PEEK available to order in weights starting at 100g to allow for introductory testing.

  • Not for human implantation

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.
