What is PETG good for compared with PLA?

PETG is tougher, more flexible and holds up better to heat and moisture than PLA. PLA still wins on ease of printing and fine detail.

What nozzle and bed temperatures does PETG need?

Most PETG prints around 230–250°C at the nozzle and 70–85°C on the bed. Start in that range and adjust for your printer.

Yes, on most printers with a heated bed. An all-metal hotend helps at the higher end of the temperature range.

It is 1.75 mm filament, the standard for most consumer FDM printers. Check that your printer specifies 1.75 mm rather than 2.85 mm.

It warps much less than ABS, but it strings more than PLA. Tune retraction and keep the filament dry to reduce it.
