This article we found might be guilty of a tiny bit of link-baiting, but that doesn’t diminish a great grouping of 3D printing projects build around robotic arms instead of the cartesian box robots. We have shown several of these videos before, but it is worth re-examining them as a group and considering other automated tools we could explore for 3D printing.

From Gigaom.com:

We’ve heard a lot about 3D printed robots, but what about robots that can 3D print? Not all 3D printers come in a microwave-sized box; some are attached to robotic arms that can provide more creative ranges of motion and larger print areas. They can also print custom materials with some very strange applications. Here are four robotic arms that print out of the box….

Read on to read details about the four robots. And check out project videos for each of them below.
