Carbon Fiber PEEK


CF PEEK is classified as an experimental material for advanced users.


While you are free to use any brand and type of material you wish on your AON3D machine, we can only provide support for AON3D-approved materials that we have tested and developed processes for in-house, all of which can be purchased from AON3D directly by contacting

General Process Settings

Setting Value
Extrusion Temperature 400-470ºC
Bed Temperature 160-180ºC
Chamber Temperatures 110ºC

Usage Notes

Build Surface Preparation

CF PEEK prints best on the High Temperature PEI build plate with the use of a raft. Note that surface of the PEI plate should be periodically resurfaced using a mill, or with an orbital palm sander if no milling services are available.

Material Pre-treatment

CF PEEK is extremely susceptible to moisture uptake. We recommend drying the filament overnight at 100ºC before use, and to always store in a sealed container with dessicant. Take care to check the spool material of your filament prior to baking your material. Some vendors use low temperature materials for spools which may melt or deform at bakeout temperature.

Please contact for any questions on this matter.

Support Material

There is currently no compatible support material for CF PEEK - prints will require self-support.
