We have developed a density controllable magnetically modified photocurable polymer. Using this developed polymer and microstereolithography, we fabricated three-dimensional magnetic microstructures with neutral buoyancy. This polymer is composed of photocurable polymer, magnetic particles, a viscosity increasing agency, and hollow microcapsules. Because the density of the hollow microcapsules is low, we can adjust the density of the polymer by changing the concentration of the microcapsules. Furthermore, we constructed a mathematical model for the density and magnetic properties of the density controllable magnetically modified photocurable polymer. We expect our developed polymer will become a key material for achieving three-dimensional controllable magnetic micromachines.
