本研究利用金屬3D列印技術設計並一體成形製造蒸汽腔體，材料採用 SUS316L，腔體尺寸為 62.5mm × 62.5mm × 5mm。毛細結構選用 TPMS Gyroid，並設定兩種孔隙率（30%、60%）及三種充填率（100%、150%、200%），以探討其在不同加熱功率（20W~150W）下的熱性能表現。
在製造過程中，針對3D列印方式進行試驗與改進，並執行後處理、洩漏測試及可靠性測試。結果顯示，所製造的蒸汽腔體具備良好的緻密度與結構完整性，且能夠長時間穩定運行，驗證了一體成形製造的可行性。
可靠性測試結果表明，3D列印製造的蒸汽腔體需經過多次實驗，才能達到最佳性能。在熱性能方面，孔隙率60%的腔體展現較低的熱阻與更高的熱負荷能力。充填率方面，100%充填率在低加熱功率下具備較低熱阻，而200%充填率則能承受更高的熱負荷，150%充填率的表現則介於兩者之間。

This study utilizes metal 3D printing technology to design and manufacture vapor chambers as a single integrated structure. The material used is SUS316L, and the chamber dimensions are 62.5mm × 62.5mm × 5mm. A TPMS Gyroid capillary structure is selected, with two porosity levels (30% and 60%) and three filling ratios (100%, 150%, and 200%) to investigate thermal performance under different heating power levels (20W~50W).
    During the manufacturing process, various 3D printing methods were tested and optimized, followed by post-processing, leakage tests, and reliability assessments. The results indicate that the fabricated vapor chambers exhibit excellent density and structural integrity, ensuring long-term stable operation and confirming the feasibility of integrated manufacturing.
    Reliability test results show that 3D-printed vapor chambers require multiple experimental optimizations to achieve optimal performance. In terms of thermal performance, vapor chambers with 60% porosity demonstrate lower thermal resistance and higher heat load capacity. Regarding the filling ratio, a 100% filling ratio provides lower thermal resistance at low heating power, whereas a 200% filling ratio supports higher heat loads. The performance of the 150% filling ratio falls between the two.
