Two-polymer microtransfer molding (2P-μTM), an advanced microtransfer molding technique, is developed for fabrication of 3D microstructures. The use of two different photocurable prepolymers and a simple and robust filling and coating method allows an extremely high yield in layer-by-layer microfabrication able to produce highly layered microstructures with high structural fidelity (see Figure).
