We've got some boundary-breaking 3D printers and printing technologies in this slideshow, which includes several versions of multi-materials machines, two different composites processes including one at microscale, and two vastly different metals processes. As before, some of them come from countries outside the US.
Most of these are available now, some designed for prototyping and some for production parts. A few are new R&D developments that you won't be able to buy anytime soon, but with the potential to change the game down the line. That's probably true of all three microscale techniques we tell you about: copper microprinting, graphene-based supercapacitors, and microscale composites.
