本研究結合雙噴頭 FDM 3D 列印與脫脂燒結技術，開發銅-不鏽鋼雙金屬零件的製造流程。使用銅粉末含量 87-90 wt%與316L不鏽鋼粉末含量90 wt%之複合線材，探討燒結溫度(1273 K、1473 K、1598 K)、燒結時間(1、2、3小時)、幾何構型(包裹型、疊層型、交叉型)、排氣通道設計及加壓條件對成品的影響。熱物性分析結果顯示銅-不鏽鋼複合材料的熱傳導係數介於純不鏽鋼與銅之間，相較於純不鏽鋼提升了2.5倍。確定1598 K為最適燒結溫度，但發現3小時燒結雖能實現最充分界面擴散但導致過度燒結，1小時燒結保持良好外型但界面結合較弱。加壓燒結技術能顯著改善燒結效率與品質，在1339 N⸱m-2壓力下，疊層型試片1小時燒結獲得優異的外觀品質與機械性能。最佳製程參數組合為：疊層型設計、1598 K燒結溫度、1小時加壓燒結，此條件下複合材料楊氏係數達16.048 GPa，最大應力達100.727 MPa。本研究成功以FDM製程製備銅-不鏽鋼雙金屬零件，並發現孔洞形成的主要成因為燒結過程銅蒸發。為雙金屬積層製造提供了另一種可能的方法。

This study developed a manufacturing process for copper-stainless steel bi-metallic components to combine high thermal conductivity with mechanical strength using dual-nozzle FDM 3D printing and debinding sintering techniques. Two types of composite filaments were used: one containing 87-90 wt% copper powder, and the other containing 90 wt% 316L stainless steel powder. These materials were investigated under varying sintering temperatures (1273-1598 K), sintering durations (1-3 hours), geometric configurations, and pressurized conditions. The optimal parameters-layered design, 1598 K sintering temperature, and 1-hour pressurized sintering (1339 N⋅m-2)-achieved Young's modulus of 16.048 GPa, maximum stress of 100.727 MPa, and thermal conductivity 2.5 times higher than pure stainless steel. Copper evaporation during sintering was identified as the primary cause of void formation. This research provides an alternative approach for bi-metallic additive manufacturing.
