PETG-CF basics: PETG sits between PLA and ABS: tougher and more heat resistant than PLA, but still printable without an enclosure. As a starting point, print PETG-CF at 240–270°C with the bed at 65–85°C; an enclosure helps on big parts. The temperature range printed on the reel always wins: it varies between brands and between colours of the same brand.
