3D printing on a much larger scale

The end goal of this giant rapid prototyping machine is to print buildings. We’re not holding our breath for a brand new Flintstones-esque abode, but their whimsical suggesting of printed buildings on the moon seems like science fiction with potential. The machine operates similar to a RepRap but instead of plastic parts, it prints stone by binding sand with epoxy. This method is not revolutionary, but hasn’t really been seen in applications larger than a square meter or so. It’s fun to see the things we dabble in heading for industrial production applications.
