摘要
本研究透過選擇性雷射熔融技術(Selective Laser Melting, SLM) 3D列印技術製造一系列金屬3D列印毛細結構之試片，分別為不同線寬之網格式排列毛細結構與晶格式毛細結構。首先測試金屬3D列印毛細結構試片之孔隙率，使用阿基米德法與直接量測法求得兩組數據，將實驗求得之孔隙率與理論值進行比較，用以理解列印前後之孔隙率差異。接著量測金屬3D列印試片之毛細力與滲透率表現，藉此實驗找出孔隙率與毛細力、滲透率的表現是否有關連性。 結果顯示，金屬3D列印之晶格式結構中，OCTET此晶格結構在本實驗所有不同結構之金屬試片中，擁有最低孔隙率，同時在毛細力中表現最為突出，300秒內流體最大芯吸量達到0.36克，最大芯吸速率達到0.015克/秒。 最後將網格式排列毛細結構應用於均溫板中，分別製造含有毛細結構與無毛細結構之均溫板，進行整體熱阻測試，測試毛細結構是否能有效降低整體熱阻。

In this study, a series of metal 3D printing capillary structures were fabricated by Selective Laser Melting (SLM) 3D printing technology. First, the porosity of the metal 3D printing capillary structure sample was tested, and two sets of data were obtained by using the Archimedes method and the direct measurement method. The experimental porosity was compared with the theoretical value to understand before and after printing. The performance of capillary force and permeability of the metal 3D printed test piece was measured, and the performance of porosity, capillary force and permeability was found out by experiment. The results show that among the lattice structures of metal 3D printing, the lattice structure of OCTET has the lowest porosity among all the metal test pieces of different structures in this experiment, and has the most outstanding performance in capillary force, with the largest suction capacity within 300 seconds. The suction capacity reached 0.36 grams and the maximum advance speed reached 0.015 grams per second. Finally, the grid-arranged capillary structure is applied to the vapor chamber, and a vapor chamber with capillary structure and no capillary structure is fabricated respectively, and the overall thermal resistance test is carried out to test whether the capillary structure can effectively reduce the overall thermal resistance.
