- What temperatures should I print Cailab PETG at?
- PETG generally prints around 230–250 °C at the nozzle and 70–85 °C on the bed. Start near the middle and adjust for your printer and part cooling.
- Does PETG need an enclosure?
- No. PETG warps little, so an open printer works. An enclosure mainly helps with drafts and large parts.
- Is PETG food safe?
- PETG itself is considered food-contact safe by many makers, but printed layers trap bacteria and most brass nozzles contain lead. Do not assume a printed part is food safe.
- How does it compare with PLA?
- PETG is tougher, more heat-resistant and slightly flexible, but stringier and harder to print cleanly. PLA is easier and gives sharper detail.
- How should I store it?
- Keep it sealed with a desiccant when not in use. PETG absorbs moisture, which causes popping and weak, cloudy prints; dry it if it has been out.
- Does it work on a Bowden-tube printer?
- Yes, but PETG's flex and stringiness favor direct drive. On Bowden setups, lower retraction speed and increase distance slightly.
- Where is the PETG 3D Printer Filament 1.75 mm cheapest?
- At Lowe's, for $74.45, as of our latest check.
