4D Printing of Composites [PDF ebook] 

This book introduces the novel and rapidly developing field of 4D printing. The concept of 4D printing of composites extends 3D printing by adding the dimension of a transformation over time. With applications in engineering structures such as aircraft, automobile, wind turbine, sport equipment, this technique introduces programmable matter that can change conformation in contact with humidity, temperature and other external factors.
