Filament specs explained
What each spec on a filament page means, why it matters, and typical values by material.
- What bed temperature should I use? What the bed temperature range on a filament means, typical values for PLA, PETG, ABS and more, and fixing poor adhesion.
- What is chamber temperature? What chamber temperature means for 3D printing, which filaments need an enclosure, and how warm the air should be.
- What is filament density? What filament density in g/cm³ means, typical values for PLA, PETG, ABS and more, and why it changes how far a spool goes.
- What is diameter tolerance? What filament diameter tolerance means, why ±0.02 mm beats ±0.05 mm, and how uneven filament affects your prints.
- How hot can I dry filament? Filament drying temperatures for PLA, PETG, nylon and more, how long to dry for, and why damp filament prints badly.
- How many metres in a 1 kg spool? How many metres of filament are on a 1 kg spool of PLA, PETG, ABS and more, and how density changes the length.
- What does minimum nozzle size mean? Why some filaments list a minimum nozzle size, which fills need 0.4 or 0.6 mm, and when you need a hardened nozzle.
- What nozzle temperature should I use? What the nozzle temperature range on a filament means, typical values for PLA, PETG, ABS and more, and how to tune it.
