| Summary: | 碩士 === 國立臺北科技大學 === 製造科技研究所 === 103 === This research is focusing on the system development of subtractive and additive manufacturing for thin-shell structured object. The purpose of this system is to provide future possibility to be used in manufacturing customized elastic orthotics. There are system development and the pre-study of its application in this research. The system development includes the new manufacturing process, the new hardware to perform the process, the new software to help designing the dedicate application, and the material used in this process.
Nowadays ,the additive and subtractive combination manufacturing process are mostly fall into Directed Energy Deposition (DED) or Powder Bed Fusion (PBF) process followed by CNC cutting process. These processes normally come out with good outer surface but not inner surface. Moreover, the processes are not suitable to some soft and elastic materials.
Based on the successful development experience of customized insole designing and manufacturing system, and the toe box machining system, a new process has been proposed in this research. This process is using cylindrical coordinates and the subtracting first algorithm to bring the possibility of thin-shell with structured object in which has a smooth inner surface. The NC machining is used to build up the support block which has a smooth outer surface. Followed by the Material Extrusion (ME) process, it will deposit soft and elastic material additively on the top of the support block. By controlling the tooling path of the extrusion nozzle, a proper laced thin-shell structured can be fabricated on it. This thin-shell structured will have the copy of the outlet of the block on the inlet to provide a smooth felling on human skin. By a proper design of the object, it will bring a new age to customized elastic orthotics.
This research isto developing the equipment of subtractive and additive manufacturing. It should be able to NC machining and build up the thin-shell with structured object. The dimension of the t object is 100mm×200mm.
