Abstract

We have designed and constructed a femtosecond laser two-photon polymerization (TPP) system and explored its processing capabilities through experiments. By performing single-point processing experiments with varying laser energy, the energy range for photoresist polymerization was determined. By adjusting the scanning speed and laser energy, the minimum achievable line width of the fabrication system was obtained. What’s more, in combination with the precision of the translation stage used, suitable laser energy and scanning speed were selected to fabricate structures resembling the ruins of the Parthenon, which demonstrates the excellent processing capabilities of our fabrication system.
