An anatomical model (manikin) that can be used for studying anatomy and training for surgery is required in the medical field. By stacking particles that are the same size as the cell, an anatomically accurate manikin would be produced. However, it is difficult to handle cell-sized particles, so we make a manikin by stacking particles with a diameter of 0.33 mm with controlled color and hardness. Manikin is made from two types of silicone oil, a pigment and a photocrosslinker. By irradiating ultraviolet light to silicone oil, silicone gel of any color and hardness would be made. First, a 0.33 mm thickness of transparent silicone gel sheet with dents arranged at intervals of 0.33 mm is produced. Next, a colored silicone oil is dropped into these dents and cured by ultraviolet light to produce a silicone gel sheet with colored particles. Finally, this silicone gel sheet is stacked to make a manikin. Since the hardness and color can be changed for each particle, the manikin is more accurately to the color and hardness of the human body. In this paper, the manikin material and modeling technique are proposed and confirmed by experiments.
