本論文致力於改進實驗室自行開發的高速頁寬式半導體雷射積層製造設備，用以提升其列印品質和擴展應用範圍。其中，列印槽粉末預熱系統為本次改良的重點項目，原始機台在列印TPU時容易產生翹曲及收縮，造成列印失敗或是外觀品質不佳，透過精心的設計和優化，將原始點偵測紅外線測溫儀更換為面偵測形式之紅外線測溫CCD，讓使用者能更清楚粉末溫度分布，並加入智能自動溫控系統，配合測溫CCD偵測粉末溫度，自動改變持溫燈輸出功率，使被列印模組遮擋後降溫的粉末迅速回到設定溫度，成功克服了列印過程中的挑戰，使其達到更穩定且精確的預熱效果，並進一步對TPU的列印參數進行了優化和調整，以確保最佳的列印效果和品質。
此次改進不僅提升了機台的整體性能，更使其能夠成功列印出原始機台無法實現的316L不鏽鋼複合材料，並透過試片對比，統整出高速頁寬式半導體雷射積層製造設備相較於目前市售的商用機台的優勢與劣勢，成功拓展了頁寬式機台之材料多樣性。

This thesis aims to improve the high-speed page-wide semiconductor laser additive manufacturing equipment developed by our laboratory to enhance its printing quality and expand its application range. The powder preheating system of the printing tank is the primary focus of this improvement. The original machine tends to experience warping and shrinking issues when printing TPU, leading to printing failures and poor appearance quality. Through meticulous design and optimization, replaced the original point detection infrared thermometer with a surface detection infrared temperature measurement CCD. This upgrade allows users to have a better understanding of the temperature distribution of the powder. By integrating an intelligent automatic temperature control system with the temperature measurement CCD to detect the powder temperature, the output power of the temperature-holding lamp can be automatically adjusted. This ensures that the cooled powder, obstructed by the printing shaft, quickly returns to the designated temperature. These enhancements effectively overcome the challenges encountered during the printing process and yield a more stable and precise preheating effect. Furthermore, the TPU printing parameters were optimized and fine-tuned to guarantee optimal printing results and quality.
This improvement not only enhances the overall performance of the machine but also enables successful printing of 316L stainless steel composite materials, which were previously unachievable with the original machine. By comparing test pieces, we have summarized the advantages and disadvantages of high-speed page-wide diode laser additive manufacturing equipment in comparison to current commercial machines, while successfully expanding the material diversity of the page-wide machine.
