Kasey's Korner: This material can withstand forces 160,000 times its own weight

July 9, 2014 8:56 am | by Jon Dipierro, Multimedia Production Specialist | Videos | Comments

MIT engineers have created a new material that can withstand forces 160,000 times its own weight. The material uses micro lattices with nanoscale features for a material that offers great strength with ultra low density. The researchers utilized a high-precision 3d printing process called projection micro stereolithography to create a material that is 400 times stronger than an object of similar density.
