In this study, authors aim at developing microsurgery tool in the next generation by rapid digital manufacturing technique. The full use of hybrid stereolithography method make it possible that the complicated, high-density, and tiny structure can be made by intermittent embedding metals or other materials into the photo-cured resin matrix on the way of the stereolithography process. In the first half of this report, the pullout strengths of original hybrid test bars were verified to have the enough strength for clinical use. It could be confirmed that the tendency of the plots of interlaminar shear stresses, for the different implantation lengths of the stainless steel tube, was equal to the theory of strength of composite materials. In the latter half, the new layout design and geometry modeling of the microsurgical tool, especially the design of a flexural joint with the fiberscope, were performed for the future utilization of the hybrid stereolithography technique.
