When it comes to 3D printing there seems to be few limits to what the technology can do or what range of products it can spawn, from lampshades to lunar bases. It’s easy to neglect one key factor amid all the hype: Printing capabilities are directly wedded to the size of one’s printer. As home printers become more readily available, the size of their printing beds shrink. Any budding designer with a desktop 3-D printer can create an intricate scale model of the Millennium Falcon, but what about something as straightforward yet functional as a chair? It simply won’t fit inside the printing box.
