This paper ．馬達殼體 Motor Housing presents an application of 3D printing for the sand mold of motor housing. The manufacturing process 摘要(Abstract) includes the transformation from final product to cast embryos, flow channel design, casting simulation, 隨著 3D 列印技術的進步，已可應用在許多領 casting process, sand-mold design and printing. The 域。本文說明了應用 3D 列印砂模在開發馬達殼體 authors also discuss the difference between the 3D 的過程，包含成品圖轉換成鑄胚圖、流道設計、鑄 printed sand mold and the traditional sand casting. We 造模擬、澆鑄過程，以及 3D砂模設計與列印；並 realize that the use of 3D printing for sand mold is 說明使用 3D 列印砂模與傳統砂模鑄造之差異。 able to eliminate the time and cost of manufacturing 在開發的過程中，發覺使用 3D 列印砂模相較 process compared with the traditional sand casting 於傳統的砂模鑄造製程，除了免去製造模型的時 process.
