Highlights: • (Cu, Ni) honeycomb structure with pore size of ~11 μm and wall thickness of ~200 nm was prepared. • The morphology evolution and the potential formation mechanism of the (Cu, Ni) honeycomb structure were investigated. • A new template-free method of additive manufacturing combined with etching was proposed to prepare ordered porous structure. • This work provides important insights into the preparation of ordered porous structure without template. - Abstract: Metallic ordered porous structures have attracted increasing attention due to their wide range of applications, but their preparation is usually accompanied with the employing of consumable templates. The development of template-free method to prepare metallic ordered porous structure can significantly reduce the cost as well as streamline the procedures. In the present work, a new template-free method of additive manufacturing combined with etching was proposed to prepare ordered porous structures. (Cu, Ni) honeycomb structure with pore size of ~11 μm and wall thickness of ~200 nm was successfully prepared from the Fe-Cu-Ni precursor alloy. The morphology evolution and the potential formation mechanism of the (Cu, Ni) honeycomb structure were studied. This work provides important insights into the preparation of ordered metallic porous structure without template.
