This study aims to develop the manufacturing method of micro-structured parts by the metal powder injection molding (MIM) inserted micro-sacrificial plastic molds which were prepared by nano-imprint lithography (NIL) technique. In this process named NIL/p-SPiMIM, the feedstock composed of nanoscale copper powder and polyacetal-based binder was adequately prepared and molded into polymethylmethacrylate films with fine line-scan structures, and it was sintered in a reductive gas atmosphere followed by solvent debinding of the films. The filling rate of feedstock into micro-channels and transcriptional property in sintered parts was evaluated by SEM observation. It can be concluded that the manufacturing method named NIL/R-SPiMIM proposed in this study has great potential to produce precisely 3 dimensional complex metallic parts with fine micro-structures.
