    About grey PETG-CF

    SpoolDeal tracks 3 grey PETG-CF listings on Amazon UK and Eryone UK, 3 of them in stock right now, from £19.99 per kilogram; the typical price is £20.00/kg. They come from 3 brands, including IEMAI, ERYONE, eSUN.

    Grey is the easiest colour for judging print quality and a good base coat for painting miniatures and models.

    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.

    Colour names vary between brands, so check the listing photos before buying if you need to match an existing reel. Every card shows the live price and whether it is in stock, and the list is sorted by price per kilogram.
