- What is PETG good for compared with PLA?
- PETG is tougher, slightly flexible and holds up better to heat and moisture than PLA. It is a good pick for brackets, holders and parts that get handled.
- Does it need a heated bed?
- PETG prints best on a heated bed, typically around 70–80 °C, with a nozzle around 230–250 °C. Check your printer's recommended range before printing.
- Is it harder to print than PLA?
- Yes, somewhat. PETG strings more, prefers slower speeds and can bond too strongly to bare glass or PEI, so a release agent or the right surface helps.
- Is 1.75 mm the right diameter for my printer?
- Most hobby FDM printers use 1.75 mm filament. Confirm your printer's spec, since some older machines use 2.85 mm.
- Does black PETG show layer lines?
- Black tends to hide layer lines and smudges better than light colors, though glossy PETG still shows layer texture under direct light.
