PEEK 3D printing
PEEK sits at the top of the plastics pyramid. It keeps its strength in continuous heat up to about 250 °C, resists a very wide range of chemicals, wears slowly, and survives repeated steam sterilization. It's the pick for the most demanding parts, and our most expensive material.

The top of the plastics pyramid — PEEK combines extreme heat resistance, outstanding strength, and excellent chemical and wear resistance in one material. Handles continuous service near 250°C and can be sterilized. The choice for aerospace, medical, oil & gas, and the most demanding end-use parts. Natural or black finish.
Properties
- Strength
- Very high, tough, and wear-resistant
- Flexibility
- Low (stiff)
- Heat resistance
- Extreme (continuous use up to about 250 °C)
- Chemicals
- Excellent (oils, fuels, solvents, hot water, steam)
- Fire
- Flame-retardant (UL 94 V-0)
- Finish
- Natural tan or black
- Density
- 1.3 g/cm³
Best for
- Aerospace, oil and gas, and industrial end-use parts
- Parts that live in constant high heat
- Lab tools and fixtures that get sterilized again and again
- Bushings, seals, and wear parts that run hot
Consider something else for
- Parts that don't truly need its heat or chemical resistance (PC Blend, Nylon GF, or PPS-CF often do the job for far less)
- Medical implants or anything that goes inside the body
- Bright colors (PEEK comes in natural tan or black)
