Carbon Fiber Polyetherketoneketone (CF PEKK)

PEKK and its filled carbon fiber version are classified as experimental materials 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 330-360ºC
Bed Temperature 120-140ºC
Chamber Temperature 110-120ºC

Usage Notes

Build Surface Preparation

CF PEKK prints best on the AON-M2 High-Temperature Build Plate, but does not generally require 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.

Material Pre-treatment

CF PEKK is susceptible to moisture uptake. We recommend drying the filament overnight at 100ºC before use, and to always store in a sealed container with desiccant. 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 bake-out temperature.

Please contact help@aon3d.com for any questions on this matter.

Support Material

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