Abstract

The traditional two-photon polymerization manufacturing technology encounters two difficulties in fabricating submillimeter/micron-scale structures: excessively long fabrication time and weak structural strength, causing collapse of the structure. To solve these problems, this research first develops a new laser scanning path planning strategy, namely, the contour scanning method with inner supports. The concept is to reduce the fabrication time by manufacturing only submillimeter/micron structural shells as well as to generate the support structure below the horizontal area of the shell to enhance the structural strength. In this study, a method for generating a laser scanning path is presented, and a simple micro-cuboid and a micro-calcaneus with complex shape are fabricated to verify the proposed method. The method can effectively reduce the fabrication time and prevent submillimeter/micron structure collapse.
