Is PETG better than PLA for functional parts?

Yes for most functional parts. PETG is tougher and handles more heat than PLA, at the cost of more stringing and slower printing.

Does it need an enclosure?

No. PETG prints without an enclosure and warps far less than ABS, though a draft-free room helps.

Most users print Polymaker PETG around 230–250 °C with a bed near 70–80 °C, then tune from there.

It is 1.75 mm filament on a 1 kg spool, which fits most common FDM printers; check your spool holder's width and weight limit.

PETG absorbs moisture, so dry it if you hear popping or see bubbles, and store it sealed with desiccant.

Polymaker does not market this PETG as food safe, and printed layers can harbor bacteria, so avoid food-contact use.
