本實驗室有很多與陶瓷漿料快速原型系統相關的研究。而本論文的目的在於開發塑膠漿料快速原型系統。 本研究內容分為兩個部份,分別為建構系統與測試以及計設熱風乾燥器。 由於以底板加熱乾燥方式乾燥生坏時,由生坏表面往底部,溫度逐漸上升,因此較高的疊層厚度,坏料底部的溫度會更高,過高的溫度會使塑料熔化而損壞工件。為此嘗試開發熱風乾燥器,對生坏表面加熱,使生坏底部溫度降低。 控制系統是以個人電腦做為主控制器,四軸運動控制卡主要是負責供料機構、鋪料機構、清料機構、X-Y雷射掃描平台以及精密Z軸平台之運動控制。系統建構的工作內容包含,整合人機介面、設備接線及設備測試等。 經實測結果此快速原型系統,可讓Z軸平台的定位標準差在正負0.76μm以內。熱風乾燥器,乾燥厚度30μm的生坏,在15秒內完成,達到製程要求的乾燥條件。
There are many researches about ceramic slurry rapid prototyping system in our laboratory. However, the aim of this study is to develop a plastic slurry rapid prototyping system. The content of this study includes two parts: system construction and test, hot air drier design. Because the temperature of the bottom heating drier is getting higher from the top of the green part to the bottom of the green part, the bottom temperature will be higher if the part thickness is higher, overheating will damage the plastic part. For this reason, this study tries to develop a hot air drier which heats the top layer of the part and the bottom temperature of the part can be reduced. The PC was a main controller of the control system. A 4 axes motion control card was employed to control the material feeding mechanism, paving mechanism, material cleaning device , X-Y laser scanning platform and Z direction platform. The work of system construction included man-machine interface software integrating, electrical circuits wiring and equipment testing. According to the experimental results, the positioning error of Z direction platform could be reduced to +-0.76μm.Hot air drier could reach the requirement of slurry process;it dries the 30μm thickness layer within 15 seconds.
