Explore the possibilities of 4D printing: Programmable matter at the Microscale

Micro 4D printing builds on programmable matter

Objects which can change themselves once they are built have many applications, from robotics to medicine. A new technique that uses 3D printing with an ink containing dynamic chemical bonds allows for the creation of microscale structures with variable sizes and properties.
