Tiny Shape-Memory Devices Made from Liight

Aug-31-16 Researchers have developed a new way to print 3D soft shape-memory devices that could be used to help deliver drugs in the body.

Developed by a team from MIT, along with the Singapore University of Technology and Design, new printing process (called microstereolithography), uses projected light to print patterns on layers of resin. This novel technique allowed the team to create structures as small as the diameter of a hair—much smaller than anything that has been possible before. The team was able to print an array of structures, which are able to stretch up to three times their length without breaking, and then shift back into their original shape within seconds when exposed to a certain temperature.
