eSun is one of the top suppliers 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. They take excellent care of the 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.
