WELCOME TO CURIOSUM (former Sliperiet)

In April 2019, Sliperiet changed it´s name to Curiosum and merged with the science center Umevatoriet. This autumn we will take the next step. and together with our tenants move into the renewed premises of Sliperiet at Arts Campus at Umeå University.

In 2020 Curiosum will open. A new science center, to inspire young and old with science and technology. We believe curiosity can change the world.

Look out for our new website coming soon!

Hangprinter- new 3D-printing method demonstradet at Sliperiet

Sliperiet at Umeå Arts Campus is in the process of making a 3D printed Tower of Babel using a novel hanging printer. The new method deployed offers a low-cost solution with increased flexibility to print large volumes.

A new type of 3D printer has been demonstrated at Sliperiet as part of ongoing  +Project - an EU funded R&D initiative. Suspended on thin fishing lines, 'Hangprinter' is currently printing a structure inspired by the Tower of Babel. The machine's innovative spiderlike set up does not depend on a box, frame or rails; the printer can instead be attached to any stable surface, opening up a number of opportunities.

The tower is under construction but already measures almost three-and-a-half metres - not only the tallest object made by the Hangprinter so far, but much taller than the scope of any commercially available large format printer.

"As far as I know, the HangPrinter is the only 3D printer of its kind. There are parallel cable-driven robots and other cable-driven 3D printers, but the HangPrinter is unique in that all the parts except the energy source are mounted on the mobile device, and that it can use existing structures - in this case the walls - as a frame," says Torbjørn Ludvigsen, inventor of the HangPrinter.

Cost-efficient 3D printing

Torbjørn Ludvigsen started working on the HangPrinter while still a student at Umeå University, and the initial motive for designing a hanging printer was to bring down production costs:

"The frame or box was almost half the cost of the final 3D printer, and I thought I could do without it."

Torbjørn Ludvigsen proved its feasibility with a first prototype last year and has been improving the method and device ever since. The printer can be put together for around EUR 200, a fraction of the cost of other large format printers.

"With a 3D printer unconstrained by a set frame or box, prints can become as tall as whatever it can be suspended from, while the horizontal print area is unconstrained by a set frame," says Linnea Therese Dimitriou, Creative Director at Sliperiet. She immediately saw the potential in the device and suggested printing a Tower of Babel to test it on a larger scale.

"I find this technology very exciting as it gives us new and increased flexibility. Opportunities include printing over vast areas and printing large volumes - horizontally and vertically - without the need to build rails or frames. The setup could also be scaled up and adapted for other materials. Future versions of the device could be equipped with sensors for greater precision and outdoor use. The tower project at Sliperiet, where attachment points are moved along as we ascend, shows that this is a feasible idea," says Linnéa Therese Dimitrou.
