説明
<jats:title>Cross-scale coordination</jats:title> <jats:p> Laser-based additive manufacturing has the potential to revolutionize how components are designed. Gu <jats:italic>et al.</jats:italic> suggest moving away from a strategy that designs and builds components in a serial manner for a more wholistic method of optimization for metal parts. The authors summarize several key developments in laser powder bed fusion and directed energy deposition and outline a number of issues that still need to be overcome. A more integrated approach will help to reduce the number of steps required for fabrication and expand the types of structures available for end-use components. </jats:p> <jats:p> <jats:italic>Science</jats:italic> , abg1487, this issue p. <jats:related-article xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="doi" related-article-type="in-this-issue" xlink:href="10.1126/science.abg1487">eabg1487</jats:related-article> </jats:p>
