PEEK 3D Printing Filaments Product Description

High-temperature resistant

1.Glass transition temperature: 143°C

2.Heat distortion temperature: 152°C

3.Long-term using temperature: 260°C

4.Short-term using temperature: 300°C

5.Melting point: 343°C

High toughness

Unfilled virgin grade PEEK filaments has better toughness than fiber filled grade,Elongation at Break is 45%.No-break at unnotched impact.Still keep

toughness under Low temperature -40°C.

Fatigue resistance

The fatigue resistance of PEEK is stronger than most thermoplastic materials. It can undergo 107 cycles of operation under a stress level of 30-35 MPa.

Light weight & High strength

tensil strength: 100MPa,Flexural Modulus:4.1GPa,

Flexural Strength:170MPa,Density:1.3g/cm3,it is a ideal to replace metal

|How to print PEEK material?

PEEK has high melting point,so it need high processing Temperature to print smooth,it is important to keep the nozzle over 390°C.

Material	drying Temperature	drying time	nozzle Temperature	Platform Temperature	Chamber temperature:	printing speed
PEEK	150°C	3H	390-430°C	100-140°C	133-162°C	15-50mm/s

●PEEK material after 3D printing ,it needs Annealing process to Eliminate internal stress and enhance crystallinity!After annealing can make the PEEK printed parts has better heat resistance and ccorrosion resistance

|PEEK 3D Printing Filaments Advantages

●Excellent tensile strength

● Increase the heat distortion temperature of the material

● Enhance high-temperature stability and durability

●The printing success rate is as high as 95%

●It is widely applicable to FDM/FFF printing models

PEEK Printed coponents showcase

Backed by the ±0.02mm precision tolerance and high roundness control of Pures PEEK filament, your printer will consistently deliver finished-part quality far beyond that of ordinary filaments:

Fine layer lines and a smooth surface finish—achieving an appearance close to injection-molded parts with virtually no post-processing required.
Dimensional accuracy stable within ±0.1mm; parts won't deform or crack, and can go straight to assembly verification or final installation.
Dense interlayer bonding with zero pores or silver streaks; mechanical properties at 260°C are fully aligned with the raw material's nominal values—enabling PEEK 3D printing to truly leap from "barely doable" to "reliable, trustworthy, and a direct replacement for machining."
