Additive manufacturing (AM) for mechanical devices and electronic components has been actively researched recently. While manufacturing of those mechanical and electronic devices has their own merits, combining them into a single form is expected to grow by creating new applications in the future. The so-called all-printed electromechanical devices have potential applications in mechanical, electrical, and biomedical engineering. In this paper, the recent advancement in all-printed electromechanical devices is reviewed. A brief introduction to various AM techniques is presented first. Then, various examples of sensors, electronics, and electromechanical devices created by AM are reviewed.
