High Resolution Dual Material Stereolithography for Monolithic Microdevices

Functional 3D components such as perfusion channels and mechanical actuation elements at cellular length scales can support cell survival and tissue maturation in tissue modeling devices. These advanced requirements call for increasingly complex materials and 3D fabrication methods. Here, a high‐resolution dual‐material 3D printing concept is developed, where distinct materials are produced locally by orthogonal chemical reactions depending on...
