3-D printing with custom molecules creates low-cost mechanical sensor

Imagine printing out molecules that can respond to their surroundings. Chemists teamed up with engineers who are using 3-D printers to create 3-D printed objects with new capabilities. Scientists created a bone-shaped plastic tab that turns purple under stretching, offering an easy way to record the force on an object.
