Three-dimensional structures with micro-/nanoscale features can be produced by two-photon polymerization lithography but suffering from a non-uniform shrinkage. Here, the authors report a poly(vinyl alcohol)-assisted pick-and-place process to uniformly heat shrink three-dimensional micro-/nano-architected materials printed by two-photon polymerization lithography.
