Pro PETG Print Settings – 3D-Fuel

We don't have slicer profiles for Pro PETG yet. They're a lower priority for us because a generic PETG profile works decently well. Start from your slicer's generic PETG profile and use the settings below.

Expect to raise the hotend temperature. Pro PETG is pure, virgin PETG. Many PETG filaments on the market aren't virgin or aren't pure, and they print cooler. To get the best print quality and part strength from Pro PETG, you'll likely need a higher hotend temperature than a generic profile uses.

Recommended settings

Setting	Recommendation
Nozzle temperature	245–265°C. Our PETG prints a little hotter than some.
Bed temperature	70–80°C.
Enclosure	Not needed.
Pressure advance and flow	Calibrate both for your printer.
Drying	65°C for 8–12 hours before printing.

Temperature and finish

Print hotter for a glossier finish and stronger layers. One customer found 250°C gave a matte look and 260°C gave the glossy finish they wanted. If you print fast, you'll usually need the upper end of the range.

Volumetric speed

If your slicer's maximum volumetric speed is set too high, Pro PETG can't melt fast enough, which gives under-extrusion and a rough, matte finish. One Creality K2 Plus customer fixed this by lowering it from 16 to 8 mm³/s and fine-tuning flow.

Calibration

Pressure advance (called flow dynamics in Bambu Studio) and flow ratio make a big difference with PETG. The steps are the same as for Pro PCTG:

Diamondback and other high-conductivity nozzles

Nozzles that transfer heat very efficiently usually print 5–10°C cooler than a standard nozzle, and sometimes up to 15°C cooler. Print a temperature tower with the new nozzle to find the right setting.
