本研究重點於應用頁寬式雷射之高速 3D 列印技術，頁寬式雷射可於
單次掃描行程，即可完成列印區域內之圖像成型掃描，有別於單顆雷射燒
結的 3D 列印設備，需要於列印區域內使雷射光斑往復來回掃描於粉體表
面上，而頁寬式雷射的雷射數量愈多，則可列印之區域愈大，以達到高速
3D 列印之目的。
　　本研究初期以改良實驗室先前研究之設備為主，頁寬式雷射源數量由
先前研究之 64 顆改為 448 顆，因此改良了光學模組的機構及相關配置，
以符合高速 3D 列印製程。改良設備時，同時進行聚丙烯粉末之研究，分
析 3D 列印之通用聚丙烯粉末性質及燒結測試，發現該粉末不適用於本研
究之半導體雷射，故開發聚丙烯複合粉末。
　　完成聚丙烯複合粉末的性質分析與相關燒結測試後，根據得到相關之
列印製程之參數，以改良後的設備對聚丙烯複合粉末進行多層數燒結列印
樣品，驗證製程參數，再對樣品進行性質分析。
本研究成功改良頁寬式雷射之光學模組及列印出聚丙烯複合粉末之樣
品，未來若有雷射源數量增加及粉末無法成功燒結的問題，可參考本研究
之流程，作為改善之方案。

This research focuses on the application of the high-speed 3D printing technology of the page-wide diode laser. The page-wide diode laser can complete the image forming scan in the print area in a single scanning, which is different from the single laser sintering. The 3D printing equipment in the print area needs to scan the laser spot back and forth on the surface of the powder. The more the number of lasers of the page-wide diode laser, the larger the print area to achieve high speed 3D printing.

In the initial stage of this research, we focused on improving the equipment previously studied in the laboratory. The number of page-wide laser sources has been changed from 64 in the previous study to 448 in order to meet the high-speed 3D printing process. While improving the equipment, research on polypropylene powder was carried out at the same time, the properties of general polypropylene powder for 3D printing and sintering test were analyzed, and the polypropylene composite powder was developed.

After completing the property analysis of the polypropylene composite powder and related sintering tests, the polypropylene composite powder is printed with multiple sintering samples, and then the properties of the samples are analyzed.

This research has successfully improved the optical module of the page-wide diode laser and printed samples of polypropylene composite powder. If there is an increase in the number of laser sources and the powder cannot be sintered successfully in the future, you can refer to the process of this research as an improvement program.
