Compliant Rolling-contact Architected Materials: Part 3 Fabrication at the Micro-scale

Compliant rolling-contact architected materials (CRAMs) are lattices of compliant rolling-contact joints, which consist of criss-crossing flexure straps deformed around the contours of cams that roll along each other's surfaces like gears. This video shows how they can be fabricated on very small scales using two-photon stereolithography and scanning holographic optical tweezers.
