    A very short guide. Always check the range on your own spool, as brands differ.

    • PLA: easiest to print and good for display pieces and prototypes. Softens at around 55 to 60 °C, so do not leave it in a hot car.
    • PETG: tougher and more heat resistant than PLA, good for functional parts. Tends to string.
    • ABS: strong and heat resistant but warps and gives off fumes. Needs an enclosure and good ventilation.
    • ASA: like ABS but better for outdoors and sunlight, which matters in strong sun.
    • TPU: flexible. Print slowly, and it is easier on a direct-drive extruder.

    Which filaments and brands do you trust, and where do you buy them?
