eSUNs eTwinkling filament is a brand new material for 3D Printing. It is a composite PLA material also biodegradable. Similar to PLA, it is tough, odorless, low shrinkage, good rigidity, does not require a heated bed, and can be printed at high speed.

eSun is a top supplier of 3D printer filament, and we’re happy to be carrying their inventory. They are not some fly-by-night operation; eSun is an active part of the 3D printer community, and you’ll often see them represented at Maker Faires and 3D Printer Expos. We’ve even been to their labs at the Shenzhen University grounds where they develop and test their product. They take excellent care with their production methods, and each spool comes vacuum sealed in a pouch with moisture-absorbing desiccant.

In short, eSun knows their stuff. We’re extremely happy with the quality and consistency of their material.
