Abstract: A method for manufacturing a target material is provided, including the steps of: disposing raw material powder on a substrate and melting the raw material powder by laser to form a target material layer; repeating the preceding process to allow a plurality of target material layers to form an integrated target material column; after cooling the target material column, removing the target material column from the substrate; and performing vacuum heat treatment on the target material column. Since the target material is additively manufactured and subjected to vacuum heat treatment, the target material has a finer and more uniform microstructure, thus improving the product quality.
