本計畫提出一個研究，以完成一套基層製造支援軟體為目標，能改善基層製造的應用範圍與方便性。我們的支援軟體會先讀入物體的幾何模型，接著進行體素化(Voxelization) 計算，將模型轉成3維體積資料(Volume data)，然後在這個體素資料中產生模型的支架，並進行切片的工作，將實體資料轉成2維影像資料；最後利用影像處理技術找出切面區域的邊界與範圍、曲線、線段與離散點，產生機器碼。我們的軟體有下列優點:(一)我們將體素資料當做中間資料，並輸出來，可用於視覺化與找尋錯誤。(二)體素化的工作可以簡化整個資料轉換工作，例如支架的產生與切面的產生。(三)因為使用體素化，我們可讀入任何能夠進行體素化的幾何資料，不必為每一種幾何格式製作一套機器碼產生軟體。(四)基層製造的精準值可以調控，我們利用體素化的網格精密度，可以調整切片厚度與切面上的區域精準度，可適用不同三維列印機。此外我面也會考慮將體素資料進行壓縮與編碼，並將此支援軟體與雲端計算結合，讓使用者可從遠端執行機器碼得產生工作，接著下載機器碼與中間結果，然後在自己家裡進行列印。 In this research project, we develop an innovative 3D printing supporting system for layered manufacturing. In the proposed system, input models can be represented as polygonal meshes, parametric surfaces, point cloud sets, or volume data sets. At first, the system will convert input models into volume data sets by using a voxelization method. Then the support structures of input models are built inside the volume data sets. In the following steps, volume data sets are divided into slices and topological information hidden in the slices are retrieved by using image processing techniques. Finally, based on the topological information, the target machine codes are generated. Compared with the current LM supporting systems, our supporting system possesses at least the following advantages: (1) crucial intermediate results are available for visual display and debugging, (2) the voxelization computation simplifies the code generation process, (3) using volume data as the kernel data structures, our system is capable of processing more types of geometric models, and (4) the precision of the manufacturing is tunable by adjusting the resolution of the voxelization process. Furthermore, we also intend to expand the scope of the data transformation process by embracing newest technologies of geometric data compression and large data processing so that layered manufacturing can be integrated with cloud computing systems and the availability of layered manufacturing is increased. In order to detect errors, we also construt a simulator which an reveal the progression of the printing process. It helps users to compare the printed model and the original model in advance. The printing parameters as well as printing time ans material consumption are also displayed.
