Functgraph: Personal Factory Automation With a 3D Printer

IEEE Spectrum

Over the past few years, we’ve seen 3D printers used in increasingly creative ways. There’s been a realization that fundamentally, a 3D printer is a full-fledged, multi-axis robotic manipulation system—which is an extraordinarily versatile thing to have in your home. Rather than just printing static objects, folks are now using 3D printers as pick-and-place systems to manufacture drones, and as custom filament printers to make objects out of programmable materials, to highlight just two examples.

In an update to some research first presented at the end of 2019, researchers from Meiji University in Japan have developed one of the cleverest 3D printer enhancements that we’ve yet seen. Called Functgraph, it turns a conventional 3D printer into a “personal factory automation” system by printing and manipulating the tools required to do complex tasks entirely on the print bed. A paper on Functgraph, by Yuto Kuroki and Keita Watanabe, was presented at the Conference on 4D and Functional Fabrication 2020 in October.
