摘要

快速原型原理是利用層堆疊的方式來建構三維的實體工件。目前的快速
原型系統是以上照式為主，其缺點是材料浪費過大，且在複合材料的製作
應用上，有製程技術的困難。因此，本研究開發下照式多樹脂面成型快速
原型系統以解決上述之問題。本系統之原理是利用數位微型反射鏡元件輸
出每一層之光罩，再輔以不同的漿料槽以達到製作複合材料原型之目的。
此系統的開發包含有Y 與Z 方向的伺服滑台、光罩輸出系統和自動化程式
控制等光機電整合來製作工件。首先以三維模型經過光罩軟體，切出每層
截面輪廓圖，層厚設定為20μm，經過一連串動態光罩與滑台平移動作(Y 方
向伺服滑台)及成形平台(Z 方向伺服滑台)的升降動作，最後完成實體工件。
本實驗的項目有漿料成分最佳化、粉末顆粒對成型性的影響以及工件製作
之分析。

The principle of rapid prototyping is producing three-dimensional solid part
by layer forming method. Currently most of rapid prototyping system is masked
solid imaging which is over wasted of the material. Moreover it had
technological difficult for manufacturing application of composite material.
Therefore, an experimental study is conducted to developed Bottom-Up
Exposure Multi-Resin Stereolithography Using Dynamic Projection Technology
to solve the problems as indicated as first section.
The principle of this system is using Digital micromirror device to output
every layer of photomask and puting into different Resin tank for reaching the
objective of manufacturing application of composite material. This
optomechatronic integration system includes Y-Z direction Servo-hydraulic
Slider, photomask output system and auto-programmable control to manufacture
working component. First, we put three-dimensional solid part into photomask
software and display every sections of outlines with 20μm depth. After a shifting
movement of dynamic mask and sliding table(Y direction Servo-hydraulic) and
a rising and falling movement of forming plate Z direction Servo-hydraulic).
Finally, we establish our working component.
iii
Cases covered in this study including sizing optimization and analysis the
influence of dust on forming and manufacturing working component.
