PETG Filament is commonly used in 3D printing, has the following characteristics:

PETG Print Settings:

1. We recommend printing our PETG settings at roughly 235C-255C depending on your extruder.  The PETG bed temperature works best around 70-90C, a few degrees hotter perhaps for those first few layers.
2. What’s the best surface to print PETG on? Well in our experience, blue painter’s tape works the best.  PETG bed adhesion can work great with other materials though, providing you follow the next (very important) step.
3. This material doesn’t need to be squeezed onto your heated bed, you want to leave a slightly larger gap on the Z-axis to allow more room for the plastic to lay down. If the extruder nozzle is too close to the bed, or the previous layer it will skim and create stringing and build-up around your nozzle.  We recommend starting off moving your nozzle away from the bed in 0.02mm increments until there is no skimming when printing.
4. The Fan: essentially if you want the strongest possible print, print with no fan. The higher PETG filament temperature will aid the super-strong layer adhesion. The molten PETG will stick to the previous layer ridiculously well.  But if you need better detail, and no stringing, you really need to use 100% PETG cooling fan.  The rapid cooling after leaving the nozzle will leave your prints detailed, with no stringing or blobbing.
