MIT’s new Rapid Liquid Printing technique can print large items, like furniture, in minutes. The Rapid Liquid Printing technique differs from traditional 3D-printing methods in that the polymer material is extruded directly into a container of translucent gel. This allows the object to be printed in midair, in a way, and requires no extra support structures to help it hold shape. The Rapid Liquid Printing material will also harden when it contacts the gel, eliminating the need for curing by heat or UV light. The gel-based method drastically reduces printing time, with an object being printed in ten minutes that would have taken 50 hours traditionally.
