Description

SUNLU PETG is a tough, impact-resistant filament for functional parts: enclosures, holders, organizers, and outdoor items. It's noticeably tougher and more durable than PLA, yet it prints with minimal warping and strong layer adhesion. The formula is tuned to reduce stringing and eliminate clogging for consistent, reliable prints.

Density: 1.27 g/cm³, 1 kg spool
Less stringing and no clogging thanks to neat winding

PETG is hygroscopic and absorbs moisture from the air. Dry a wet spool at 65 °C for about 8 hours before printing, otherwise you'll get bubbles and stringing. Adhesion is strong — keep cooling moderate so layers bond properly.

This line works with most FDM printers that have a heated bed — from bedslingers like the Ender 3 to fast CoreXY machines. An enclosure and a hardened nozzle aren't required. It's a great pick when you need parts stronger than PLA without the hassle of ABS: waterproof holders, brackets, boxes, and outdoor-rated parts.
