Stretchable, Flexible, Recyclable: This Plastic is Fantastic

Princeton engineers have developed an easily scalable 3D printing technique to manufacture soft plastics with programmed stretchiness and flexibility that are also recyclable and inexpensive—qualities not typically combined in commercially manufactured materials. In an article in the journal Advanced Functional Materials, a team led by Emily Davidson reported that they used a class of widely available polymers called thermoplastic elastomers to create soft 3D printed structures with tunable s...
