A lattice structure, originally printed flat, has morphed into the outline of a human face. CREDIT: Lori K. Sanders Researchers have succeeded in 4D-printing material lattices that can shape-morph ...

Aerospace undergrad Alex Kuehnle observes PhD student Ivan Wu in the composites laboratory at the University of Illinois Urbana-Champaign. Because it’s costly and cumbersome to transport large ...

In the aeronautic and aerospace thin-walled structures, hole shape designs are very popular to achieve the weight reduction, structural reparation, cooling and other purposes and have important ...

Wooden objects are usually made by sawing, carving, bending or pressing. But now, scientists have developed flat wooden shapes extruded by a 3D printer which can be programmed to self-morph into ...

In a new Harvard University-designed system, however, that buckling action allows flat-packed objects to be twisted into useful three-dimensional forms. Most existing "buckling-induced deployable ...
