Approach that enables the microfabrication of compliant rolling-contact architected materials (CRAMs). a Our system can be used to directly print CRAM lattices with already curled straps as long as b gaps and spacers exist in the design. Such lattices fail to function, however, when they are slightly c over-exposed or d under-exposed. Our system can also use scanning holographic optical tweezers to deform the flexure straps after they have been printed straight to fabricate e compliant rolling-contact joints (CRJs) and f CRAMs with stored strain energy so they can achieve their intended properties (scale bar in c and d 10 μm, e 20 μm, f 30 μm)
