Rapid micropatterning of polymers on rigid and flexible substrates can be achieved by the method—vacuum‐assisted micromolding in capillaries (MIMIC)—introduced here. The Figure shows an oblique‐view SEM image of a single hexagonal cell of a pattern produced by vacuum‐assisted MIMIC. The use of vacuum reduced the time taken to fill the pattern with UV‐curable polyurethane from ∼30 min to ∼15 s.
