氧化鋯材料具有高熔點、高機械強度、高化學穩定性且在高溫下能維持其結構穩定性和機械性能，目前被廣泛應用於高溫陶瓷組件、牙科與醫療領域、電子材料…等，並可藉由添加不同金屬氧化物製備成不同色澤之氧化鋯成品。本研究之氧化鋯複合粉末製備使用開合式密鍊機搭配自行開發與調配之蠟基黏結劑配方與氧化鋯粉末進行加熱混合，並在混鍊過程中藉由添加碳黑粉末將反射率從原始粉末的78.5%降至15.28%，混鍊後之氧化鋯複合粉末相較於原始粉末具有較大粒徑，並透過SEM觀察到粉末間呈現高分子拉絲狀情形。使用Sinterit Lisa SLS 3D列印機進行生胚列印成型實驗，該列印設備具備雷射能量5W，波長808nm之半導體雷射，在列印溫度90°C、列印層厚100µm、雷射能量密度0.052J/mm2參數進行列印下，可獲得最大密度3.00 g/cm3，達到95.8%之生胚理論密度值。後製程中進行溶劑脫脂與燒結處理，在溶劑脫脂，溫度50°C、脫脂時間9小時下脫脂率可達到6.79%，去除黏結劑中蠟量94%之重量；燒結實驗中，燒結溫度1600°C，持溫4小時下，體積收縮率來到47.63%；燒結後胚體密度為5.47g/cm3，達到理論值91.32%，相比最低密度值提升3.2%；維氏硬度值達到1415HV，並藉由XRD進行內部晶相分析，確保內部皆以正方晶相存在。透過本研究所開發之陶瓷複合粉末並藉由半導體雷射燒結成型，有別於選擇性雷射熔融成型可以以較低功率雷射能量、免於使用真空或是惰性環境下進行列印，其成品可保持外觀完整且生胚具有一定之強度。

Zirconia Oxide material possess high melting point, high mechanical strength, and high chemical stability, allowing them to maintain structural stability and mechanical properties at high temperature.
In this study, a Zirconia Oxide composite powder was prepared by self-developed wax-based binder system and Zirconia Oxide powder using an open-chain mill. During the mixing process, the reflectivity of the powder was reduced from 78.5% to 15.28% by adding carbon black powder as a coloring agent. The resulting zirconia composite powder had larger particle size compared to the original powder.
The printing machine, Sinterit Lisa SLS 3D printer equipped with a 5W, 808nm wavelength semiconductor laser, was used for the experimental printing of green parts. Under the printing parameters of 90°C printing temperature, 100µm layer thickness, and laser energy density with 0.052 J/mm2, a maximum green part density of 3.00 g/cm3 was achieved, reaching 95.8% of the theoretical density.
During solvent debinding at a temperature of 50°C for 9 hours, the debinding rate reached 6.79%. In the sintering experiment, at sintering temperature of 1600°C and holding time of 4 hours, the volume shrinkage was 47.63%. The density of the sintered part was 5.47 g/cm3, showing a 3.2% increase compared to the lowest density value. The Vickers hardness value reached 1415 HV.
Through the development of ceramic composite powders in this study and utilizing selective laser sintering. The resulting products maintain their integrity and the green bodies possess a certain level of strength
