Abstract
In this study, we proposed a novel micro-scale additive manufacturing method based on the optical potential formed by a Bessel beam. The proposed technique is expected to show no deterioration in manufacturing resolution due to heat generation, to be applicable to various materials, and to be able to be performed in an air environment. The basic principle of the proposed method involves accumulating and stacking particles dispersed in air by using optical radiation pressure. In this paper, 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. Finally, a pillar structure was fabricated with polystyrene particles having a diameter of 1 μm, which indicated that the proposed technique was promising for practical applications.
