Carbon Fiber Polyether Ether Ketone (CF PEEK)

A filament feed path upgrade kit is available to purchase.
This upgrade lowers the friction between the filament and the PTFE tube allowing the material to freely move to the extruder. It also increases the bending radii of the feed path, reducing the risk of the filament breaking inside the feed tube.
Please contact our Customer Success team at help@aon3d.com for special pricing.

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 sales@aon3d.com.

General Process Settings

Setting Value
Extrusion Temperature 400-430ºC
Bed Temperature 160-180ºC
Chamber Temperature 110-120ºC

Usage Notes

Build Surface Preparation

CF PEEK prints best on the AON-M2 High-Temperature Build Plate with the use of a brim or raft. Note that PEI surface of the High-Temperature Build Plate should be periodically resurfaced using a mill, or with an orbital palm sander if no milling services are available.

Please contact sales@aon3d.com if you currently have an AON-M2 Aluminum Build Plate and would like to upgrade to the AON-M2 High-Temperature Build Plate.

Filament Drying and Moisture Control

CF PEEK is extremely susceptible to moisture uptake. The filament can be dried in a convection oven at 120ºC overnight (minimum 6-8 hrs), or at 130ºC for 5 hours. Always store unused material in a sealed container with silica desiccant.

For more information, see the Filament Drying and Moisture Control page.

Support Material

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