Formlabs are continuing to create new resins for their Form 1 3D printer. Last year they rolled out their Functional Resins in "Flexible" and "Castable" flavors, and this year they're adding "Tough Resin" to the line-up. So what makes this one different?

Tough is durable, adaptive, and impact-resistant. Perfect for engineering challenges, this sturdy, ABS-like material has been developed to withstand high stress or strain. It's ideal for snap-fit joints and other rugged prototypes.

"Durable: Sturdy prototypes that will deform under pressure where other 3D prints fail."

"Responsive: Parts that absorb force; flexing and returning to form."

"Rugged: Prints that can tolerate mechanical friction and strain."

To demonstrate what the Tough stuff can do, the FormLabs team printed up a little demo a la Rube Goldberg:

While they apparently haven't scaled production up to the level where they're willing to give out free samples, as they do with their other resins, you can currently order a 1-liter bottle of the stuff for $175 (and with a one-week lead time). For now it only comes in the teal-ish color you see in the photos and video.
