Abstract
A system and method of constructing a 4D-printed ceramic object includes extruding inks including particles and polymeric ceramic precursors through a nozzle to deposit the inks on a heating plate, whereby a 3D-printed elastomeric object is formed on the heating plate, folding the 3D-printed elastomeric object into a complex structure to form a 4D-printed pre-strained elastomeric object, and converting the 4D-printed elastomeric object into the 4D-printed ceramic object.
