Abstract
The novelty in structural colors arise from recent discovery that individual elements are capable of generating a wide range of colors, instead of the use of repeated units. Here, we discuss basic structures 3D printed using two-photon polymerization lithography (TPL) to investigate new mechanisms for generating colors. Such structures enable new approaches to fully 3D print optical devices that previously rely on precise mechanical assembly, e.g. high-resolution lightfield prints. Structures printed using in-house shape memory polymer resin or elastomers allow for reconfigurable micro-prints that exhibit unique behavior under compressive and tensile stress.
