Good job!<\/span><\/p><ul><li><span style=\"color: #000000;\">Paper information: Powder bed fusion (PBF) additive manufacturing has enabled unmatched agile manufacturing of a wide range of products from engine components to medical implants. While high-fidelity finite element modeling and feedback control have been identified key for predicting and engineering part qualities in PBF, existing results in each realm are developed in opposite computational architectures wildly different in time scale. Integrating both realms, this paper builds a first-instance closed-loop simulation framework by utilizing the output signals retrieved from the finite element model (FEM) to directly update the control signals sent to the model. The proposed closed-loop simulation enables testing the limits of advanced controls in PBF and surveying the parameter space fully to generate more predictable part qualities.<\/span><a href=\"https:\/\/i0.wp.com\/depts.washington.edu\/xchenlab\/wordpress\/wp-content\/uploads\/2020\/07\/Screen-Shot-2020-07-09-at-8.26.19-PM.png?ssl=1\"><img loading=\"lazy\" class=\"aligncenter wp-image-14109 size-full\" src=\"https:\/\/i0.wp.com\/depts.washington.edu\/xchenlab\/wordpress\/wp-content\/uploads\/2020\/07\/Screen-Shot-2020-07-09-at-8.26.19-PM.png?resize=640%2C328&#038;ssl=1\" alt=\"\" width=\"640\" height=\"328\" data-recalc-dims=\"1\" srcset=\"https:\/\/i0.wp.com\/depts.washington.edu\/xchenlab\/wordpress\/wp-content\/uploads\/2020\/07\/Screen-Shot-2020-07-09-at-8.26.19-PM.png?w=640&amp;ssl=1 640w, https:\/\/i0.wp.com\/depts.washington.edu\/xchenlab\/wordpress\/wp-content\/uploads\/2020\/07\/Screen-Shot-2020-07-09-at-8.26.19-PM.png?resize=300%2C154&amp;ssl=1 300w\" sizes=\"(max-width: 640px) 100vw, 640px\" \/><\/a><\/li><\/ul><hr \/><p><span style=\"color: #000000;\">Feifei presented her work on \u201cActive interlayer heating for sustainable selective laser sintering with reclaimed polyamide 12 powders\u201d.

Limited procedures exist for systematically reusing the aged powders. This work proposes a systematic method to maximize the reusability of aged and extremely aged polyamide 12 powders. Building on a previously untapped interlayer heating, pre-processing, and a systematic mixing of powder materials, we show how reclaimed polyamide 12 powders can be consistently reprinted into functional samples, with mechanical properties even superior to current industrial norms.<\/span><\/li><\/ul><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"<p>Lab members (Prof. Chen, Dan and Feifei) attended the ISFA&hellip;<\/p>\n<p> <a class=\"more-link\" href=\"https:\/\/depts.washington.edu\/xchenlab\/lab-members-attended-the-isfa-international-symposium-on-flexible-automation-2020-and-were-nominated-for-the-finalist-of-isfa-2020-best-paper-award-in-theory\/\">Read more<\/a><\/p>\n","protected":false},"author":5,"featured_media":14090,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"spay_email":""},"categories":[1],"tags":[],"jetpack_featured_media_url":"https:\/\/i1.wp.com\/depts.washington.edu\/xchenlab\/wordpress\/wp-content\/uploads\/2020\/07\/107876106_655264371730948_4733505055006618555_o.jpg?fit=1024%2C512&ssl=1","jetpack_sharing_enabled":true,"jetpack_likes_enabled":false,"jetpack-related-posts":[],"jetpack_shortlink":"https:\/\/wp.me\/pbs2Dq-3Fe","_links":{"self":[{"href":"https:\/\/depts.washington.edu\/xchenlab\/wp-json\/wp\/v2\/posts\/14088"}],"collection":[{"href":"https:\/\/depts.washington.edu\/xchenlab\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/depts.washington.edu\/xchenlab\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/depts.washington.edu\/xchenlab\/wp-json\/wp\/v2\/users\/5"}],"replies":[{"embeddable":true,"href":"https:\/\/depts.washington.edu\/xchenlab\/wp-json\/wp\/v2\/comments?post=14088"}],"version-history":[{"count":22,"href":"https:\/\/depts.washington.edu\/xchenlab\/wp-json\/wp\/v2\/posts\/14088\/revisions"}],"predecessor-version":[{"id":14116,"href":"https:\/\/depts.washington.edu\/xchenlab\/wp-json\/wp\/v2\/posts\/14088\/revisions\/14116"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/depts.washington.edu\/xchenlab\/wp-json\/wp\/v2\/media\/14090"}],"wp:attachment":[{"href":"https:\/\/depts.washington.edu\/xchenlab\/wp-json\/wp\/v2\/media?parent=14088"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/depts.washington.edu\/xchenlab\/wp-json\/wp\/v2\/categories?post=14088"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/depts.washington.edu\/xchenlab\/wp-json\/wp\/v2\/tags?post=14088"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
