| Summary: | 碩士 === 國立中正大學 === 機械工程系研究所 === 107 === In recent years, the development of additive manufacturing technology has been highly spotted. For example, from the early technology of Rapid Prototyping to some recent technique such as Selective Laser Melting, Fused Deposition Modeling and Digital Light Processing, have been widely used in various fields. Compared with traditional processing, the raw material is processed through a subtractive process such as cutting and honing, the advantage of layered manufacturing is the method using stacking layers with the additive process, which can effectively reduce material waste. Also, the additive manufacturing can be differentiated through simple process, such as product design, model slicing, route planning and mask forming system to import design objects to the machine for printing. For the users, in addition to the more convenient model design, the subsequent modification and simulation calculation of the process can be performed more effectively by cutting the 3D model of the object into a 2D layered slice.
The focus of this research is on the development of the digital light processing additive manufacturing software for the construction of external support structures and their mask forming systems. The software flow is mainly divided into three parts, which is the optimal construction angle, the model slicing and the support construction output. The user first inputs the model, and obtains the construction direction with the smallest support area by the object rotation simulation detection. Then the support area contour is calculated through the slice process and the support structure is established. Finally, we will output the model contour and the supports profile of each layer together with the format of mask image. And the model can be printed on the light curing machine.Therefore, the main objective of this study is to determine the direction of the minimum support area by the constructing angle to reduce unnecessary support consumables, and to establish a more suitable support structure for the light curing process, so that the print quality of the object appearance, the support structure and the integrity of the mask can be effectively improved.
