What temperatures should I print SUNLU PETG at?

The specs list 240-260°C nozzle and 70-80°C bed. SUNLU suggests 230-240°C at 50-100 mm/s or 240-260°C at 100-200 mm/s.

Does it string or clog?

SUNLU says it is engineered to reduce stringing and clogging. Buyers report stringing and oozing when the filament has absorbed moisture, so dry it first.

How much filament is on a spool?

One spool holds 1 kg of 1.75 mm filament, roughly 320 m.

Is it stronger than PLA?

Yes. PETG is tougher and more impact-resistant than PLA, with stated tensile strength of 46 MPa, and it handles outdoor use better.

What retraction settings work?

The specs recommend 0.8-1.2 mm retraction distance. Tune from there for your printer and dry the filament to cut stringing.
