The digitalization of manufacturing processes has led to the development of three-dimensional (3D) printing technologies that build objects, layer by layer, starting with a digital model. This type of additive manufacturing is enabling the on-demand production of functional parts with complex geometries (1). However, it is also contributing to pollution from end-of-life products, particularly those made from polymers (2). Closed-loop recycling of 3Dprinted polymers, in which a material is reused indefinitely without losing valuable properties, is a desired solution, but there is an unavoidable trade-off between the mechanical integrity of printed parts and recyclability. On page 170 of this issue, Yang et al. (3) report a circular additive manufacturing process by which lightinduced polymerization produces highperformance polymer parts that can be decomposed into reprintable liquid resins under a specific condition. This represents a major step forward in sustainable lightpromoted 3D printing.
期刊介绍:
Science is a leading outlet for scientific news, commentary, and cutting-edge research. Through its print and online incarnations, Science reaches an estimated worldwide readership of more than one million. Science’s authorship is global too, and its articles consistently rank among the world's most cited research.
Science serves as a forum for discussion of important issues related to the advancement of science by publishing material on which a consensus has been reached as well as including the presentation of minority or conflicting points of view. Accordingly, all articles published in Science—including editorials, news and comment, and book reviews—are signed and reflect the individual views of the authors and not official points of view adopted by AAAS or the institutions with which the authors are affiliated.
Science seeks to publish those papers that are most influential in their fields or across fields and that will significantly advance scientific understanding. Selected papers should present novel and broadly important data, syntheses, or concepts. They should merit recognition by the wider scientific community and general public provided by publication in Science, beyond that provided by specialty journals. Science welcomes submissions from all fields of science and from any source. The editors are committed to the prompt evaluation and publication of submitted papers while upholding high standards that support reproducibility of published research. Science is published weekly; selected papers are published online ahead of print.
