Researchers revolutionize reversible 4D printing

A team of researchers from Singapore has developed a 4D printing technique, capable of producing a 3D fabricated material which can change its shape, repeatedly, without the need for electrical components. Researchers from Singapore University of Technology and Design and Nanyang Technological University have successfully developed a 4D printing technique for the manufacture of a material, capable of changing shape without the need for electrical components. As described in research published in Engineering, the 'reversible' 4D printing technique differs from typical 4D printing, as the object is able to return to its original shape and form without any manual, electrical...
