Previously, 3D printing came with its own set of limitations. Printing an object required a support structure, layering, and time to cure. This results in a slow, small-scale process. While working with Steelcase, the Self-Assembly Lab created a technique that prints inside of a gel. With the gel acting as 360-degree support, a product designer can essentially draw in 3D space without the limitations of gravity. This makes printing faster and the product can be big as the machine available.
Unlike traditional printing, curing is done while the 3D printing is still underway. A two-part mixing process allows the material to cure chemically rather than using light or temperature.
According to MIT assistant professor Skylar Tibbits, the intricate design of their baseline table top took only 28 minutes to print. In another experiment, they were able to print a structure in 10 minutes that would have taken 50 hours using a more traditional 3D-printing method.
While only an experiment, for now, the process has caught the interest of Turnstone, a Steelcase brand. “As a designer, what’s most fascinating and unique about rapid liquid printing is the line quality of the print. It’s soft, almost organic. It evokes images of brushstrokes or the branches of plants,” Turnstone senior industrial designer Yuka Hiyoshi said. “The printing speed is very impressive. In the far future, large-scale objects could be printed in minutes instead of days. Also, it’s not limited to typical 3D printing material making the technology very desirable from a design perspective.”
For now, this collaboration will continue to experiment with materials, scale, and further improvements.
