Is Sunlu PETG worth it over PLA?

If you need tougher, more heat-resistant parts, yes. PLA is easier to print and faster, but PETG holds up better for functional parts.

How does it compare with eSun PETG?

It is described as a close comparable to eSun PETG, with similar strength and print temperatures. Either works well; tuning matters more than the brand.

What temperatures should I print it at?

Use a 240–260°C nozzle and a 70–80°C bed. The recommended settings list 240–255°C and 80–90°C, so start in the middle and adjust.

Do I need to dry the filament first?

Yes, drying is recommended even on a factory-sealed spool. Moisture causes popping and rough surfaces, and drying improves print quality.

Will it fit my printer?

It fits any 1.75mm-compatible FDM printer, including Prusa, Creality, MakerBot and FlashForge models.

Our take on the Sunlu PETG Filament 1.75mm 1kg

Sunlu PETG is a 1.75mm glycol-modified filament sold on a 1kg spool, aimed at FDM printers from Prusa, Creality and similar. It sits between PLA and ABS: easier to print than ABS, tougher and more heat-resistant than PLA, with a heat deflection temperature around 70°C and good layer adhesion. Its 240–260°C nozzle window and 70–80°C bed are typical for PETG, and it is a close alternative to eSun PETG. Owners rate it well overall, though some report stringing and the need to dry the spool before use.
