摘要

本論文的主要研究為微快速原型自動化系統開發，整合霧化鋪層技術及動態光罩軟體，導入自動化技術製作微小的3D幾何製品，微快速原型自動化系統開發，此相關技術分為三大類：霧化鋪層技術-改善傳統快速原型機在加工懸空物件時需製作支撐的缺點，並利用數位脈波控制自動噴槍提高加工精度使加工層厚控制小於10μm。切層與動態光罩軟體技術-利用實驗室自行研發的切層軟體與動態光罩軟體，並由DMD晶片配合光學系統產生動態光罩進行加工。自動化控制元件技術-導入USB控制整合全部的系統元件，使控制程式具有完整的控制機台與掌握加工資訊的能力。本文針對系統技術開發中，特別使用USB控制卡提高PC與控制元件之間的方便性，同時設定適合的加工程序進行控制，而光學部份則改善先前研究的光學成像品質，達到微小而清晰的光罩圖，霧化部份更加入擴散錐技術，提昇霧化鋪層的效果。
最後，本研究以試製微小3D零件實例驗證系統加工精度，並以2.5D光學量測系統的驗證結果，期望對微快速原型系統的開發能有所貢獻。

The subject of this research is to develop an automatic micro rapid prototyping system. This system integrates spraying coating technology to add a very thin layer of resin to the resin tank, to apply dynamic mask to exposure the cross section shape as the photo mask on the working surface, and use a PC based controller to achieve the system automation. The spray coating technology is used to improve coating accuracy. Convention liquid based rapid prototyping system using recoater to add layer. Recoater scrapes resin surface to ensure surface flatness. In order to avoid recoater tear down the working part, convention approach is building up supporting structures which connect part and the substrate. When the feature size is small, supporting structures will be very difficult to remove without break the tiny feature. The spray coating technology could add a very thin layer of resin with no shear force and there is almost no need to build up supporting structures. The spraying system employ digital control to improve coating accuracy. The results show that the thickness of coating layer can achieve 10μm.
The dynamic mask combines the optical system and mask generating software. The optic system have ability to produce a small high resolution pattern less than . The software contents slicing, dynamic mask generating, and system control. Dynamic mask system employs DMD chip and optic system to produce photo mask. Automatic control system applies USB control system to integrate all related components.
The results of the lab build micro RP system shows the ability to build small and complex 3D working part. Further studies related to system optimization is carrying on.
