Abstract
Systems and method of constructing a 4D-printed ceramic object, the method including extruding inks including particles and polymeric ceramic precursors through a nozzle to deposit the inks to form a first elastic structure and a second elastic structure, subjecting the first elastic structure to a tensile stress along at least one axis, attaching the second elastic structure to the first elastic structure, releasing the application of the tensile stress from the first elastic structure to allow the first elastic structure and second elastic structure to form a 4D-printed elastomeric object, and converting the 4D-printed elastomeric object into the 4D-printed ceramic object.
