Weird. Who thinks it’d be a good idea to extrude 3 colors at once? Two colors are weird (and print funky!), but it’s a seriously demented engineer that thinks “Hey, I think the Reynolds numbers of this molten plastic is sufficient that we can merge 3 material streams into one homogeneous strand.” I mean, REALLY. Still, here we are. Triple-color filament. Welcome to the brave new world.

It’s pretty impressive actually. You’d think that a split-color filament would schmoosh together in the nozzle, but the viscosity of the plastic just makes it get thinner, just like how candy-makers pull candy-canes into multi-colored strands. The end result is that your printed model changes color depending on how it’s rotated. It’s really a surreal effect, especially with the metallics.

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.
