摘要

運用融熔擠製成型所製作之快速原型件，必須將其支撐材料去除後，方可利用。由於現代產品之生命週期越來越短，因此如何以高效率的方式去除支撐材料，即變成一個非常重要的研究方向。本研究建構一套高彈性與高效率之去除支撐材料系統，並針對不同製程參數對於去除支撐材料之效率進行研究。研究結果發現，y=333.19x+840.93列為預測去除快速原型件支撐材料之趨勢方程式，根據此方程式，去除支撐材料的時間（y），可以藉由支撐材料的體積（x）來精準預測，預測去除支撐材料時間之誤差率可控制小於5.18%。運用最佳製程參數，快速原型件之表面粗糙度改善百分比可達41.89%。最後，本研究亦提出一般原型件與中空原型件之支撐材料去除機制。

Removing support material from rapid prototyping (RP) part fabricated by fused deposition modeling is required once the physical model is completed. Removing the support material from RP part efficiently is an important concern because the product life cycle is shorter than before. A high flexible and high efficient system for removing the support material from the RP part was developed. The effects of process parameters on the removal efficiency of support material were investigated. The efficiency of removing support materials was investigated using a set of optimum parameters. Removing time (y) can be predicted directly from the Vol. of the support material (x) according to the linear trend equation of y=333.19x+840.93. The relative error can be controlled within 5.18%. Surface roughness improvement of up to 41.89% is achieved using the optimum parameters. Mechanisms of removing support materials for the common and hollow RP parts were also presented.
