A simple creation of freestanding three-dimensional microstructures by aligned mask micromolding for biomedical applications

There are established macroscale fabrication methods to create parts of virtually any shape or size; but for components in the microscale range (thousands to tens of microns) there is a dearth of options for making 3D parts at high enough throughput to make them practical. This paper demonstrated a novel method to create novel micromolding processes that are capable of creating defect-free microscale structures with controllable three-dimensional (3D) geometry, aligned two-sided patterns, a variety of material properties, integration of multiple materials into single structures, and high fabrication throughput. While some methods are available that are capable of meeting a few of these goals, nothing exists in the current microfabrication repertoire that can accomplish all simultaneously.
