快速成型技術目前為一種結合CAD/CAM系統之自由實體製造技術，將電腦設計模型透過切層處理直接實體化，並以疊層加工的製造方式來產生實體模型。目前常見的非制式交換格式為Stereo lithography (STL)檔案，其中並無法儲存色彩的訊息。有鑑於此，本論文主要探討應用於彩色Rapid Prototyping (RP)的切層演算軟體，並且以Virtual Reality Modeling Language (VRML97)做為檔案的交換格式。
在軟體中，以Visual C++來做為建置演算法的主要語言。以此語法完成檔案輸入演算、拓樸演算、彩色切層演算和材質貼圖演算處理。最後再以線條或是輪廓偏移的方式來做彩繪的動作，並且搭配Microsoft Fundamental Classes (MFC)函式庫來輸出彩色列印。結果分別可以輸出單色或全彩的物件、材質貼圖物件和同時執行STL與VRML97兩種不同物件。
本研究最後與彩色三維噴印快速成型系統做結合測試，可得到與原CAD一樣的色彩比例實體幾何模型，這驗證了本軟體的可行性與實用性。

Rapid prototyping (RP) technology was a solid freeform fabrication technology that integrated CAD and CAM systems; it transformed computer-designed solid models to 3D solid object by slicing process, and fabricated the solid part by layer manufacturing. The input file, Stereo lithography (STL), had became the de facto standard in RP, but it could not save the color information. For this issue, we discussed the slicing software for color rapid prototyping system , and we used Virtual Reality Modeling Language (VRML97) as convert file format.
In the software, based on Visual C++, we established the importing file, topology and slicing algorithm of data, and we handled the extra algorithm for texture mapping. Finally, we set the color of contours by lined or offset, and then output the color printing by Microsoft Fundamental Classes (MFC). In the event, color object, texture object and executing STL and VRML97 file simultaneously could be output.
A 3D colored object was fabricated with a 3D color inkjet RP printer to demonstrate the feasibility of the software algorithm. The results showed that the software was capable of working with the 3D color inkjet RP printer, and had the potential for future applications.
