steelcase X MIT create customized furniture by 3D printing into liquid gel 
up until now, 3D printing has been a desirable yet limited tool for manufacturing. whilst great for creating small, one-off objects, the technique has long needed to be adapted to be used on a large, commercial level. with this in mind, scientists at the MIT self-assembly lab have collaborated with the global furniture brand steelcase and acclaimed product designer christophe guberan to yield a 3D printing breakthrough—piloting a new process dubbed rapid liquid printing. the technique allows for the creation of large scale objects in just minutes, and is poised to make large-scale manufacturing of customized furniture a reality.
