Hangprinter, the affordable large-format 3D printer

This system, invented by Swede Torbjørn Ludvigsen of Sweden, transforms a room into a large-scale 3D printing lab

What if a room turned into a 3D printer? No, it's not utopia. Thanks to the "Hangprinter" system, invented by Swedish inventor Swede Torbjørn Ludvigsen, any room can become a 3D printer for making very large objects.

This 3D printing invention uses a system of computer-controlled cables and pulleys anchored to the wall, floor and ceiling. Once the installation in the room is complete, the printer can be started. Its inventor worked about 400 hours to create this machine. This is not the first 3D printer for very large objects, such as furniture or fixtures, but in some ways the Hangprinter is unique. First and foremost is the price. The entire printing system has a total cost of just $250. So the Hangprinter is accessible to everyone.


The large-object 3D printer is also an open source project. This means that anyone can print out instructions and make their own improvements to the machine or add updates that will be available to everyone. The Hangprinter can also self-replicate. That is, it can print spare parts for itself. Swedish inventor Swede Torbjørn Ludvigsen's goal is to enable most people, and even SMEs, to make large products or prototypes without spending too much money. The source code for the Hangprinter is available on GitHub. While all the materials needed are listed in a list that includes the costs incurred by Ludvigsen for the components. The entire system can be purchased at bountysource.com. A crowdfunding site similar to Kickstarter.
