Beschreibung
Zusammenfassung:	The invention is applicable to the technical field of material preparation, and provides a 3D printing forming process of a Zn-Cu-Mn alloy porous scaffold, which comprises the following steps: heating and melting raw materials according to a set mass percentage, uniformly mixing, and preparing Zn-Cu-Mn alloy powder from a molten Zn-Cu-Mn alloy by an argon atomization method; the CAD software constructs a three-dimensional structure model of a product needing to be formed and imports the model in the STL format into a 3D printer computer for a printing task; processing by a 3D printer according to set processing technological parameters, rapidly melting and solidifying the powder under the protection of argon, stacking layer by layer to obtain a molded product, and post-processing to obtain the Zn-Cu-Mn alloy porous scaffold. Specific zinc alloy components and specification parameters are selected, and the Zn-Cu-Mn alloy porous scaffold which is stable in quality, fine in structure and excellent in mechanical
