A Swedish inventor, Torbjørn Ludvigsen, has designed a system, called the Hangprinter, which is essentially a unique, frameless assembly of wires and computer-controlled pulleys that transform any room into a giant 3D printer. The entire hardware, suspended from the ceiling and anchored to the walls of the room, can 3D print houses, cars, furniture, and a wide variety of other large-scale objects.
One of the striking features of the system is that it self-replicates itself, which means a majority of its components are 3D printed by Hangprinter itself, writes Seeker. The open source prototype lets the tinkerers download the design and experiment with upgrades, providing low- and medium-income communities access to advanced 3D printing technology.
Cable-driven 3D printers are already present in the market but Hangprinter is different in two aspects: its ability to utilize arbitrary existing structure, such as ceiling and walls, as 3D printer and a compact, low-cost, easy-to-install design with all parts mounted on a single moving unit, reports 3ders.org.
