Published on Dec 19, 2012. It all started back in 2007 when the first RepRap machine was built. The idea behind RepRap was to design a machine that could build complex parts in three dimensions using extruded molten plastic and that machine could also "self-replicate" or build itself a new machine. Since then 3D printers from all walks of life have emerged from the community, so we decided to reach out to a few of the more prominent names in 3D printing and do our usual round-up two step with them. Stay with us as we walk through some of the latest 3D printers in action, from Solidoodle with the Solidoodle 2, PP3DP with their Up! Mini, and 3D Systems the godfather of STL, with their Cube 3D.
