Developed for the users who have difficulties fitting in their industrial type printers, Hangprinter turns the whole room into a 3D printer.
Since industrial type printers receive great demand, the product range expands as well. Developed by a Swedish maker Torbjørn Ludvigsen, Hangprinter pushes the boundaries in wide format printing.
The Hangprinter is a project by Torbjørn Ludvigsen, based in the city of Umeå in the northern end of Sweden. Ludvigsen, who goes by the handle “Tobben”. It’s a RepRap variant designed by Ludvigsen apparently in 2014, but is now something a lot more than just an idea.
The Hangprinter’s name isn’t just for fun: this machine indeed has no frame at all, unless you 
count floors, walls and ceilings as such. It operates by simply hanging by cables from the ceiling and three anchor points on the floor.
Usefully, the Hangprinter can be set up in just about any room—users just need to configure the 3D printer’s firmware in accordance with where they place the individual hooks and floor mounts. Once everything is installed and calibrated, the suspended 3D printer can move about three axes: along the Z axis, by pulling or giving cable from a ceiling hanger; and side to side, by pulling or giving cable from from three floor attachment points. Since it can be assembled for just $250, it is understandable that the Hangprinter doesn’t offer incredible resolution However, it is accurate enough to fabricate very large structures without posing a serious threat to their structural integrity
