本研究致力於優化正在開發中的多雷射模組之頁寬式高速3D列印設備，該設備之技術為積層製造達到大量生產的新技術，有別於單點式雷射搭配振鏡做雷射燒結的SLS與SLM，透過多雷射模組化形成的大面積掃描，使單次行程就能加工一個切層所需要之圖形，進而減少多次來回掃描的時間以達到高速與大量生產，改善積層製造加工時間長與產量低的缺點。
實驗初期先使用模擬軟體來模擬設備運作時雷射源與驅動板之發熱狀態，確認現在設備在散熱部分的缺陷並且在軟體上模擬改善方法，以避免雷射源散熱不佳在長時間運作時導致雷射源溫度與雷射源電壓上升進而導致引響其壽命、穩定性與列印品質，使設備之安全性與續航性得以提升。
本實驗之散熱改善將會分成水冷散熱與空間散熱兩種。水冷散熱通過模擬測試通過後會實際操作設備，觀察雷射溫度以及雷射電壓是否超過極限值並加以改善。空間散熱同樣會透過模擬測試，確認風扇安裝位置、轉速、數量以及進出風口位置調整，以更進一步保障雷射與驅動器溫度降低，同時空間散熱會加裝致冷片觀察散熱效果，達到最高效率的散熱環境，確保設備之安全性。

This research is devoted to optimizing the multi-laser module page-wide high-speed 3D printing equipment under development. The technology of this equipment is a new technology of additive manufacturing to achieve mass production. Different from SLS and SLM which are using laser to sinter with single laser and galvo scanning system. With Large area scanning formed by multi-laser modularization, the graphics required for a slice can be processed in a single move, therefore the time for multiple back and forth scanning is reduced to achieve high speed and mass production, and the shortcomings of long processing time and low yield of lamination manufacturing are improved.
At the beginning of the experiment, the simulation software was used to simulate the heating state of the laser source and the driver board during the operation of the equipment, to confirm the defects in the heat dissipation part of the equipment and to simulate the improvement method on the software, so that can avoid the poor heat dissipation of the laser source, the temperature of the laser source and the voltage of the laser source will rise during long-term operation, which will affect its life, stability and printing quality, so that the safety and endurance of the equipment can be improved.
The cooling improvement in this experiment will be divided into two types: water cooling and space cooling. After passing the simulation test, the water cooling will actually operate the equipment to observe whether the laser temperature and the laser voltage exceed the limit value and improve it. The space cooling will also pass the simulation test to confirm the fan installation position, speed, number and the position of the air inlet and outlet to further ensure that the temperature of the laser and driver is lowered. Also, the space cooling will add a cooling chip to observe the cooling effect, so as to achieve the most efficient cooling environment and ensure the safety of the equipment.
