The combination of matte carbon fiber with shiny polyester tends to create a very unique, aesthetically pleasing finish.
# PCTG (Polycyclohexylenedimethylene Pthalate-glycol)
PCTG is a newer, better, alternative to PETG.
# PCTG (Polycyclohexylenedimethylene Pthalate-Glycol)
PCTG is a newer, better, alternative to PETG, compared to PETG:

# PET (Polyethylene Terephthalate)
PET is the foundation of PET-G, but without the addition of glycol as a plasticizer. Compared to PETG:
| Pros | Cons |
