Abstract
An additive manufacturing method includes: providing a metal substrate; pressing a plurality of first metal parts to weld the same on the metal substrate one by one using a welding unit through friction welding so as to form a first stacked layer laminated on the metal substrate; pressing a plurality of second metal parts to weld the same on the first stacked layer one by one using the welding unit through friction welding so as to form a second stacked layer laminated on the first stacked layer; and repeating formation of the second stacked layer until a required amount of the second stacked layers are additively laminated on the first stacked layer to obtain a final three-dimensional (3D) article.
