Is SUNLU PETG worth it?

Yes for functional prints where strength matters more than fine surface detail. At $9.34 at 3D Printing USA as of November 4, 2026, it is one of the cheaper PETG spools available.

What print settings does it need?

SUNLU lists a 230–250°C nozzle and a 50–80°C bed at 50–100 mm/s. Start near the middle of those ranges and tune retraction to cut stringing.

How does it compare with PLA?

PETG is tougher and more heat resistant but prints slower and strings more. Use PLA for display models and PETG for parts that take stress.

Does it fit a standard printer?

It is 1.75 mm filament on a 1 kg spool and works on most FDM printers with a heated bed. Check your spool holder's width before ordering.

One vacuum-sealed 1 kg spool of 1.75 mm PETG filament. No tools or accessories are included.
