碩士 === 國立臺北科技大學 === 製造科技研究所 === 105 === The demand for mass customization is increasing as part of the evolution of shoe making technologies. New scientific methods such as Additive manufacturing (AM) technologies have been implemented to manufacture midsoles of customized designs. The Delta type 3D printer has a simple structure and an end effector that requires low inertia and able to travel at high speeds is a very approiate printer to print the size of midsoles in shop. But the Bowden type feeding system together with the Delta printer, due to the elasticity of the filament material and its resistance towards the conveyor pipe, it tends to stick and doesn’t feed till the end effector regularly. This research proposes the design and development of a dual-effector Delta type fused deposition modeling system to overcome the above limitation that can efficiently fabricate customized design of midsoles using elastic materials. A direct type feeding system is implemented in this research to feed the elastic filament to the nozzle. This research discusses the development of the system hardware along with the results of using a Bowden type filament feeding system and the direct type. In this study, the filament with the stiffness of 85A and 95A are used. The maximum print speed of the system is 150mm/s with PLA filament and 60mm/s with the 85A-TPU filament. The maximum build volume of the machine is 400sq.mm in length and width and 400mm in height. The results show that an elastic filament with stiffness range of 50A to 95A can be printed. Using elastic filament materials, soft and elastic midsoles can be manufactured easily.
