Overview
CF-PETG has been our go-to material for most parts.
Colloquially it's about as strong as MDF and has the environmental resistance of a plastic sports bottle.
It has excellent printability allowing for great detail, great z strength, and deposition rates of 1KG/24hrs
We use it for most of the printed parts on the HS3, ranging from cable chain mounts to the front display housing.
Many of our staff have printed parts in CF-PETG that have done 10,000s of KMs on motorcycles, and we figure if it survives on a motorcycle, it survives most applications.

Common Limitations
The most significant faults of CF-PETG are its limited high-temperature application and its lack of stiffness.
Above 60°C continuously, it tends to creep under high loads.
not stiff/strong enough to replace “metal” parts without a significant redesign of the part/assembly
Wears out quickly when sliding continuously → Hinges OK, Gears not OK
