Japanese paper art inspires new 3-D fabrication method that goes beyond 3-D printing limitations

A research team has created complex 3-D micro- and nanostructures out of silicon and other materials used in advanced technologies by employing a new assembly method that uses a Japanese Kirigami paper-cutting method. The method builds on the team’s “pop-up” fabrication technique — going from a 2-D material to 3-D in an instant, like a pop-up children’s book — reported in January this year on KurzweilAI and in the journal Science. Those earlier ribbon-like structures yielded open networks, with limited ability to achieve closed-form shapes or to support more complex spatially extended devices.”
