4D Printing In article number 2206486 by Guiwei Li and co‐workers, a 4D printing method to endow non‐shapememory metallic materials with active properties is presented, which can realize the shape changing of selected areas during or after forming process owing to stress release generated. The methodology opens new avenues to create metallic shape‐morphing 3D structures for high‐performance engineering applications. Specifically, the 2D part precursor can be turned into fitting a 3D structure by laser stimulation to repair the gap of the space station.
