Abstract
3D structuring using photo-sensitive polymers is an attractive additive manufacturing technique. In this
technique, 3D structuring is achieved by layer-by-layer process in which 2D patterns of photopolymerized
layers are stacked. In this paper, general feature and example of the precision 3D structures
fabricated by micro-stereolithography method based on single-photon polymerization are described. In
addition, advanced technique using stack of clustered 2D patterns has been demonstrated in order to
decrease the adhesion strength between polymerized structure and laser input aperture window for the
regulated liquid surface method in the micro-stereolithography technique.
