| dc.description.abstract | 本研究以數位光處理(Digital Light Processing, DLP)3D 列印技術為基礎，進一步探索如何透過掃描式振鏡來打破其固有的列印面積限制，從而實現大面積精密列印的可能性。研究的重點在於評估振鏡對於克服傳統 DLP 3D 列印系統面積限制的潛力，並以此為手段實現將多個小型圖形拼接成一個大型圖形的目標。
影像在經過振鏡不同轉角的影響下，會產生變形。為了解決這個問題，本研究採用了單應性矩陣(Homography)方法來對原始設計圖進行預先的變形。利用這種變形後的設計圖進行列印，使得不同的圖形能夠精準地拼接在一起。此外，為了實證此方法的可行性與實用性，本研究選擇微透鏡陣列為實驗對象，實際列印出微透鏡陣列(Micro lens array)，進一步驗證了此方法的有效性。 | zh_TW |
| dc.description.abstract | This study is based on Digital Light Processing (DLP) 3D printing technology and further explores how to break its inherent print area limitation through the application of galvanometer scanners, thereby realizing the possibility of large-area precision printing. The focus of the study is to evaluate the potential of galvanometers in overcoming the area limitations of traditional DLP 3D printing systems, with the aim of achieving the seamless assembly of multiple small graphics into a large one.
Due to the influence of different rotation angles of the galvanometer, the image will deform. To solve this problem, this study adopts the Homography method to pre-deform the original design diagram. The printing is performed using this deformed design diagram, allowing different graphics to be precisely assembled together. In addition, to verify the feasibility and practicality of this method, this study selects the micro lens array as the experimental object and actually prints out the micro lens array, further verifying the effectiveness of this method. | en |
