快速原型(Rapid Prototyping, RP)製造技術的研究新趨勢在於建構具混成材料多種材質(Heterogeneous gradient material)之弁鄔坁咱鞳C此方面之應用包括醫療用植入人體之義肢零件、精密齒冠、精密傳輸管路、多層材質合金模具、高效率航太零件及可控制藥物在人體內反應時間之混成醫療藥品等。以上具弁鄔妏s件及產品無法利用傳統製造方式製作或傳統製程相當複雜且昂貴,快速原型製造技術是目前能製作具混成材料之弁鄔坁咱韞B較有效率的製程,因此混成材料快速原型技術實有其發展之必要性。
本研究的目的為建立具混成材料之弁鄔坁咱譗AD系統,讓使用者可以在一般的繪圖軟體設計物件模型後,將CAD模型轉換成目前快速原型製造系統廣泛接受的STL檔案格式,並且輸入本系統中,讓使用者對實體模型自由輸入材料種類,依照不同的材料種類和不同材料比例來合成混成材料模型,並且可將多種材質之混成材料物件模型之資料結構儲存並輸出,以利快速原型技術之後續應用。
The new research trend for Rapid Prototype (RP) manufacturing is to build the functional part of heterogeneous gradient material. For this, the application in this area can be utilized in the production of components of prosthesis, precise crown, precise pipe line, multi-storey material alloy mold, and turbine blades. In addition, it can be employed to control the reaction time of gradient medical medicines in the human body. However, the functions mentioned above cannot be produced by the traditional manufacturing process which is quite complex and expensive. Thus, the development on the production of RP is inevitable and necessary since it can produce the functional part of heterogeneous gradient material and its procedure of production is more effective as well.
The main purpose of this research is to develop the CAD system with gradient material properties and its software. In this research, the user can design an object’s geometry in any CAD software and save the designed model in STL format for RP manufacturing. Then, by the input of the CAD system of this research, users can input various types of materials freely for solid models in accord with different types and ratios of materials needed to integrate heterogeneous object models. In addition, the information about the input mentioned above can be output so that the material data of heterogeneous object models can be used for the further research on the applications for RP manufacturing.
