Abstract
The two temperature model (TTM) as well as the heat conduction equation (HCE) are used to calculate the temperature at surfaces of metal substrates during two-photon polymerization (TPP). Using TTM, the change in reflectivity of the material during one laser pulse is simulated for different initial temperatures. In addition, experiments with tempered metal substrates are performed to examine how the change of the material properties due to different temperatures influence the polymerization process.
