1. A system for forming a structure from a polymer, comprising:
a stage having a sample holder for holding a prepolymer solution and a window formed through the sample holder;
a femtosecond laser source capable of emitting a plurality of laser pulses having a first predetermined wavelength;
a second harmonic generator aligned with the femtosecond laser source to generate a second predetermined wavelength for a first portion of the plurality of the laser pulses;
a digital micro-mirror device aligned with the second harmonic generator and the window of the stage to spatially modulate ultraviolet wavelength pulses according to a first predetermined pattern so that the prepolymer solution is cross-linked into a layer of a polymer according to the first predetermined pattern; and
an objective lens aligned with the femtosecond laser source and the window of the stage to allow a second portion of the laser pulses having the first predetermined wavelength to ablate a plurality of voids in any layer of the polymer that forms in the sample holder.
