Microtransfer molding (uTM) is a technique in which liquid prepolymer fills the recessed regions of the mold, and excess prepolymer is removed from the top surface using a flat edge. After placing the mold in contact with a rigid substrate, the prepolymer is cured by appropriate means. Micromolding in capillaries (MIMIC) is a technique that uses capillarity to fill a series of channels in a topographically patterned PDMS stamp with a fluid, low-viscosity polymer or ceramic precursor.
