Is PETG harder to print than PLA?

Yes. It needs higher nozzle and bed temperatures, slower speeds and tuned retraction to control stringing. It also bonds strongly to bare glass, so use a release agent or a textured sheet.

How does PETG compare with ABS?

PETG is stronger with better layer adhesion, more chemically resistant and prints with less odor and warping. ABS still wins on very high heat resistance and sanding and smoothing with acetone.

What nozzle temperature should I use?

Most PETG prints around 230 to 250 C with a bed near 70 to 85 C. Start in the middle of that range and adjust for stringing and layer adhesion on your printer.

Does the filament need drying?

Yes. PETG absorbs moisture from the air, which causes popping, bubbles and weak layers. Dry the spool before use and store it sealed with desiccant.

What is the 1 kg spool good for?

It covers a large number of small functional parts or one or two medium prints. Check that your spool holder and printer accept a standard 1 kg reel.

PETG resin itself is generally considered food-contact safe, but printed parts have layer gaps that harbor bacteria, and colorants and additives vary. Do not assume a printed part is food safe without a specific food-safe claim.
