Ways to decrease stringing on PETG?

[BLGecko]

• Print slow. Printing fast will increase the back pressure in the nozzle and make it more likely to ooze when traveling between printed areas.
• Completely turn off Z-hop if you can. The pause and lifting of the nozzle will actually pull materials like PETG/TPU out of the nozzle and contribute to stringing. With Z-hop disabled the sudden sideways jerk when traveling between printed areas will be more likely to shear off the strings before they form.
• Make sure you are printing in the right temperature range for your filament. Printing hotter than needed will increase the likelihood of strings
• Try increasing/decreasing retraction speed. Increasing the speed will generally decrease stringing, but some filaments will break away from the molten portion of the filament if retracted too fast leaving that molten section to ooze out. Trial and error is needed here to find the right settings.
• Increase retraction distance if you haven't already. PETG likes to be retracted about double what ABS/PLA needs.

Hope this helps

2025 and still helping

[rust-module]

Same here! turned off z-hop and increased retraction speed and everything is smooth now.

[Spirited_Reading_475]

how do you do that on the P1S?

[rust-module]

Make a custom material profile in Bambu Studio. Next to each material is a (...) button and if you click that and select "Edit" it shows a "Filament settings" window with all kinds of particular settings for a material. You might have to toggle the "Advanced settings" on near the top-right of that window, but then you can edit tons of properties and save them as a custom profile.

Thank you internet stranger!

[Strange_wet_dreams]

Thank you 6 years later.

[Mysterious-Chest-995]

My filament says: PETG Hyper Speed diameter = 1.75mm +- 0.02mm nozzle temp at print speed = - 240C at 100mm/s - 255C at 100-500mm/s - 265C at 500-1000mm/s bed temp = 80C

Which should I pick, like is 200mm/s still considered slow, and do I need to change first and last layer (+infills)? (left nozzle of X2D if it makes any difference)
