Repairing and reusing plastics and delivering cancer drugs more effectively are two of the many potential applications a new 3D/4D printing technology might have. The technology merges 3D/4D printing and photo-controlled/living polymerization — a chemical process to create polymers. 4D printing is a subset of 3D printing where the printed object can transform its shape in response to certain conditions. The new method uses visible light to create an environmentally friendly “living” plastic or polymer. Polymers can be synthetic, such as plastic, as well as biological; for example, DNA.
