| Outline of Final Research Achievements |
In this study, we proposed a novel micro-scale additive manufacturing method based on the optical potential. The basic principle of the proposed method involves accumulating and stacking particles dispersed in air by using optical radiation pressure. In this project, the water droplet of several μm in diameter containing particles suspended in space were successfully trapped in the optical potential of Bessel beam and then the only particles were deposited on the substrate. As a result of processing experiment, the silica particles with a diameter of 1 μm could be three dimensionally structured on the axis of the Bessel beam. The trajectory of the accumulated particles was numerically estimated and experimentally observed. The numerical and experimental results agreed well; specifically, the background flow carried the particles to the optical axis of the Bessel beam, and then the particles were localized at the bottom of the optical potential valley on the substrate.
