## Variants
### PETG-CF (Carbon Fiber PETG)
Carbon fiber stabilizes molten filament, and given that PETG struggles with overhangs, PETG-CF has massively improved print support quality, along with improved stiffness.
The combination of matte carbon fiber with shiny polyester tends to create a very unique, aesthetically pleasing finish.
