This is a review of journal papers on additive manufacturing, also known as 3D printing, published until April 2024 with a focus on structural engineering including material, design, fabrication, construction, education and sustainability issues. The AM-related articles have been increasing exponentially since around 2013, now piling up to astronomical figures in the world. Despite this enormity, the author is brave enough to select only 177 articles which must reveal the basic movement of AM for structural engineers, being urged by the current state that such a review paper has never been published in Japan. The readers of this paper will find that many challenging research topics are advancing and further that a variety of digital technologies are playing in the AM world.
