Material and spool size

SUNLU PETG filament is supplied as a 1 kg spool of 1.75 mm Polyethylene Terephthalate Glycol in black. It suits makers who need a single material that bridges the ease of PLA with the durability of ABS for functional prints. Buyers who require a different diameter or a larger spool capacity should look elsewhere.

Print temperatures and dimensional accuracy

The manufacturer recommends a nozzle temperature of 240-260 °C and a bed temperature of 60-70 °C with print speeds of 50-200 mm/s. Diameter tolerance is held to ±0.02 mm, which reduces the chance of extruder blockage and keeps stringing low during normal printing.

Layer adhesion and long-term toughness

The filament delivers strong layer bonding that resists warping and maintains structural integrity over extended use. High impact strength and weather resistance make printed parts suitable for indoor and outdoor applications that must endure repeated stress without cracking.

Questions about this item

How do I load the 1.75 mm filament and set the correct nozzle temperature?

Heat the nozzle to 240-260 °C, set the bed to 60-70 °C, then feed the filament until it extrudes cleanly; the tight ±0.02 mm tolerance prevents most feed issues.

What ongoing care does the spool need to keep printing reliably?

Store the 1 kg spool in a sealed bag with desiccant when not in use; PETG absorbs moisture, which causes bubbles and weak layer adhesion.

At what print speed does the material start to show layer-bond problems?

The recommended range tops out at 200 mm/s; pushing beyond that reduces the 240-260 °C window's ability to fuse layers before cooling.
