碩士 === 修平科技大學 === 電機工程碩士班 === 104 === Recently, the rapid growth of the 3D printing technology has led to the paradigm changing of the manufacture strategy. However, at the present moment 3D printing is only suitable for the fabricating of the sample and prototype, compare to the traditional injection/forming machine. In this paper, the Fused Deposition Modeling method adopts to demonstrate the possibilities of the 3D printing method on the robot arm, the Hexapod machine and the gearbox for the solar scanning/tracing system. Here the author reveals the capabilities for the rapid demonstration and evaluations for update design and further investigation. This report consists of four parts: the first part discussed abut the printing platform and the possible scheme to improve the printing qualities, then the designed robot arm is demonstrating to verify the printing qualities on the control and the kinematics configurations. The investigation on the Hexapod and the Solar scanning device is also been proceed and verified. The discussion on the comparison between the Stereolithoraphy (SLA) and the standard FDM type system (Fused Deposition Modeling) is complete and the recommendations between these two techniques are given. In the following section, the author mention about the fabrication of the robot arm, which include the using of the CAD program to complete the design concept, and setup the kinamic mode through the Arduino control board with Bluetooth control through the mobile device. Similar to the robot arm, the design procedure of the Hexpod is quite similar to the kinematic of the arm. The only different is that the numbers of the server motor that required the additional control board (TOROBOT board), and one need to aware the motion frame that keeping the balancing of the Hexapod. Finally, during the designing of the solar scanner gear box, one need to pay attention on the number of the gear-tooth, the size of the gear and the tolerance criterion. This report suggestion that the FDM printing procedures is more suitable than the SLA method.
