Hanging 3D printer builds tower of Babel




Sweden’s Umea University has developed a 3D printer that is connected with thin fishing line from the ceiling. This printer, the Hang Printer called is busy creating a ‘tower of Babel’, now more than 3.5 meters high.

The Hang Printer is according to the maker, Torbjørn Ludvigsen, the first 3D printer that works without a housing or frame rails. “The printer is unique in that all the components, from the power source, are mounted on the mobile device, and, since the existing structures can be used as a frame.” The Hang Printer hangs in the air like a spider. He was confirmed by thin lines on the ceiling and two walls on the side. The attachment points are moved on the walls with the growth of the tower.

The director of an experiment platform of the Swedish university, Therese Dimitriou, saw the potential of the device and suggested to print a tower of Babel, the Hanging Printer. She says that printing with this printer, by the absence of a frame, can be as high as the structure to which the printer can be hung. Also, the horizontal space for any prints in theory as large as the space in which is printed. According to her, this can be both vertically and horizontally across large areas prints in large volumes. Dimitriou said that the project of the Tower of Babel shows that the concept is feasible. In the future, the precision can be increased by the use of sensors.

Ludvigsen started as a student with the construction of the printer to examine how the production of 3D printers can be lowered. According to him covers the frame or box of a regular 3D printer half of the total production costs, so Ludvigsen thought that he could do without. Last year, the automaker showed a prototype of the 3D printer. The Hang Printer can approximately two hundred euros are put together, which is a lot cheaper than large-scale 3D printers.
