Is it worth it over standard PETG?

Yes if you print fast or want a matte look. Standard PETG is cheaper and prints cooler, but it is glossy and often limited to slower speeds.

Does it really print at 600 mm/s?

The filament is rated for it, but your printer and hotend set the real limit. Run 240-260°C and check that your flow and cooling keep up before pushing max speed.

Will it work in a Bambu Lab AMS?

Yes, Sunlu lists AMS compatibility. The 1 kg spool fits, and the stiffness of PETG feeds reliably through the AMS.

What temperatures should I use?

240-260°C on the nozzle and 70-80°C on the bed. Start at 250°C and 80°C, then drop the nozzle if you see stringing.

Is it food safe or outdoor safe?

No food-safe claim is made, so don't use it for utensils or containers. For outdoors, it handles UV worse than ASA and softens near 70°C.

The best new price was $13.29 at Amazon as of November 4, 2026, with 3 stores selling it new. Spool prices move with sales, so compare stores before buying several.
