This paper describes multi-segmentation of artificial muscles integrally molded by a 3D printer and simplification of post-processing. In recent years, with the improvement in performance of 3D printers, it has become possible to integrally mold flexible and hard materials. From this, attention has been focused on the integral molding of actuators that makes effective use of the complex structure of 3D printers. Most of the actuators using 3D printers use air pressure, and in consideration of the material properties, pistons using a bellows structure are common. However, the output of the piston is small because the pressure receiving area is small. Therefore, the pneumatic artificial muscle was integrally molded using the structural advantage. In this paper, we focused on the contraction length of the artificial muscle, and integrally molded the artificial muscle with the increased number of segments. In addition, the design was changed to reduce post-processing after molding. We also discussed the effect of increasing the number of segments on contraction by measuring the contraction of the artificial muscle.
