‘Pop-up’ fabrication technique trumps 3D printing

Matthew LincolnJanuary 9th 2015
  • The technique mimics the action of a children’s pop-up book — starting as a flat two-dimensional structure and popping up into a more complex 3D structure. Using a variety of advanced materials, including silicon, the researchers produced more than 40 different geometric designs, including shapes resembling a peacock, flower, starburst, table, basket, tent, and starfish.
  • The pop-up assembly technique is expected to be useful in building biomedical devices, sensors and electronics. It is the current cover story in the Jan. 9 issue of the journal Science.
  • The new pop-up method, which is based compression buckling, is fast and inexpensive, and can be used to build many different structures at one time. It uses many different materials, including silicon, incorporating different materials into one hybrid structure. It can be used to build structures on both micro- and nano-levels, and can and produce a wide range of different geometries
