PETG
BeginnerPolyethylene Terephthalate Glycol
PETG bridges the gap between easy-to-print PLA and strong ABS. It offers excellent layer adhesion, good chemical resistance, and is slightly flexible — making it ideal for functional parts that need durability without the printing challenges of ABS.
⚠ IMPORTANT: Dry Your Filament Before Every Print
All filaments — including PETG — absorb moisture from the air. Printing with wet filament causes stringing, bubbling, weak layer adhesion, and poor surface finish. This is the single most overlooked cause of bad prints.
Always dry your filament per the manufacturer's recommendations printed on the spool label before printing, especially if the spool has been open for more than a few days or stored in a humid environment. Read our complete filament drying guide →
About the Temperatures & Speeds Listed Below
The print temperatures and speeds shown on this page are general industry ranges — not a one-size-fits-all prescription. Every printer brand and model has different capabilities. A Bambu Lab X1C can print PLA at 500 mm/s; an Ender 3 with a Bowden extruder performs best at 40–80 mm/s.
Always follow your specific printer manufacturer's recommended settings and the temperature range printed on your filament spool label. Start at the lower end of the range and dial in from there.

PETG Variants Explained
PETG isn't one material — it's a family. Every variant below starts from the same base chemistry but is modified for a different job. Click through for full settings and brand picks on each.
Best For
- Functional parts
- Mechanical components
- Water-resistant prints
- Phone cases
- Tool holders
Avoid For
- High-precision parts (slight stringing)
- Very high temperatures (>80°C)
Pro Tips
- 01Reduce print speed to 40–50mm/s for best results
- 02Use a glass or PEI bed for easy removal
- 03Slightly reduce retraction vs PLA to minimize stringing
- 04Allow extra cooling time between layers
Dialed-In Print Profiles
These profiles are starting points based on community-tested settings for each printer. Your results may vary depending on your specific filament brand, ambient temperature, and printer condition. Always run a test print and adjust as needed. Speeds shown reflect what these printers are capable of — entry-level machines should use the lower end of any range.
⚠ Apply glue stick to PEI bed to prevent over-adhesion.
⚠ Reduce fan speed for better layer adhesion on structural parts.
⚠ Apply glue stick to PEI bed. Excellent results with Bambu PETG HF.
⚠ Reduce speed for best results. Glue stick prevents over-adhesion.
Print Speed by Printer Tier
Print speeds vary dramatically by printer. The speeds listed in product specs (like "500 mm/s") are maximum capabilities — not recommended everyday speeds. Use this table as a general guide and always follow your printer manufacturer's recommended settings.
PETG HF (High Flow) variants recommended for high-speed printing on Bambu machines.
Reduce speed vs PLA to minimize stringing. Follow slicer PETG preset.
PETG strings more than PLA. Slower speeds and proper retraction tuning are essential.
