What temperature should I print PETG on the Creality Ender 3?

Start at 240°C for the hotend and 80°C for the bed, then run a temperature tower across 230–255°C to dial in your exact filament brand.

What print speed works for PETG on this printer?

Around 38 mm/s is a safe starting point on the Creality Ender 3. It can go faster once the profile is tuned, but start conservative for clean walls.

What retraction should I use?

Use about 5 mm of retraction (Bowden needs more). If you see stringing, raise retraction speed before distance and dry the filament.

Do I need an enclosure for PETG on the Creality Ender 3?

No, PETG prints fine in the open on the Creality Ender 3.

PETG settings for the Creality Ender 3

Great match

⚡ Quick answer: Print PETG on the Creality Ender 3 at 240°C hotend, 80°C bed, 38 mm/s, 50% part-cooling fan and 5 mm retraction. Run a temperature tower to fine-tune your exact spool.

These are tuned starting settings for printing PETG on the Creality Ender 3. The Creality Ender 3 has a Bowden extruder with a PTFE-lined hotend, so we set the hotend to 240°C and the bed to 80°C. PETG is stronger and more temperature-resistant than PLA while still fairly easy to print.

Troubleshooting PETG on the Creality Ender 3

Problem	Fix
Stringing or fine hairs	Dry PETG before printing, drop the hotend a few degrees below 240°C, and raise retraction toward 5.4 mm. Damp filament is the No. 1 cause of stringing.
Poor first-layer adhesion	Use glue stick as a release agent to avoid over-adhesion. Re-level the bed, set a slightly squished first layer, and wipe the sheet with IPA so it is grease-free.
Blobs, zits or rough walls	Slow the outer wall, enable coasting/wipe, and keep retraction near 5 mm. Keep the part-cooling fan low so layers bond and warping stays down.
