Investigator: Assistant Professor Sing Swee Leong, ME<\/strong><\/p>\n<p>In the industry, conventional joining processes such as welding have been used in the manufacturing of multiple layered components such as antenna slots, antenna feeding, filters, radio, electronics, heat sink and shields. Additive manufacturing, or commonly known as 3D printing, provides opportunities to reduce the needs for such post-process assembly steps. In particular, laser powder bed fusion for metals (PBF-L\/M), which is also commercially known as selective laser melting or direct metal laser melting, has been proven to be feasible in fabrication of such components using different alloys. PBF-L\/M is touted to provide high resolution and precision for fabrication of complex structures as it employs lasers to fully melt metallic powder layer-by-layer to from the complex parts from digital design models. In theory, the process allows complex features to be fabricated without extensive post processing\u00a0due to this bottom-up and material consolidation approach.\u00a0However, in order to truly achieve free form fabrication, PBF-L\/M requires the use of support structures.<\/p>\n<p>The research on optimizing the design and use of support structures is still limited. Through this research, multi-stage, multi-objective optimization for the use and design of support structures will be achieved that will impact the feasibility of complex geometry fabrication as well as the final part quality by PBF-L\/M.<\/p>\n<p><strong><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/cde.nus.edu.sg\/artic\/wp-content\/uploads\/sites\/19\/2023\/03\/ADT-RP1_3.jpeg\" alt=\"\" width=\"1024\" height=\"690\" \/><\/strong><\/p>\n<p>&nbsp;<\/p>\n\n","protected":false},"excerpt":{"rendered":"<p>Adaptive and Reconfigurable Intelligent Surfaces ARIS-RP1: Design and Characterization of Ultra-Large-Scale Intelligent Electromagnetic Surfaces Using Deep Learning ARIS-RP2: Reprogrammable Meta-optics for Information Multiplexing ARIS-RP3: Making Wireless Communication Environment Smart via Reconfigurable Intelligent Surfaces (RIS): A New Network Optimization Perspective Future Computing Technology FCT-RP1: Practical Data Storage and Computation in DNA Molecules FCT-RP2: Amorphous-Oxide-Semiconductor Thin Film [&hellip;]<\/p>\n","protected":false},"author":77,"featured_media":0,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"_acf_changed":false,"site-sidebar-layout":"no-sidebar","site-content-layout":"page-builder","ast-site-content-layout":"","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"disabled","ast-breadcrumbs-content":"","ast-featured-img":"disabled","footer-sml-layout":"","theme-transparent-header-meta":"default","adv-header-id-meta":"","stick-header-meta":"","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"default","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-gradient":""},"tablet":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-gradient":""},"mobile":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-gradient":""}},"ast-content-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-gradient":""},"tablet":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-gradient":""},"mobile":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-gradient":""}},"footnotes":""},"class_list":["post-14253","page","type-page","status-publish","hentry"],"acf":[],"_links":{"self":[{"href":"https:\/\/cde.nus.edu.sg\/artic\/wp-json\/wp\/v2\/pages\/14253","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/cde.nus.edu.sg\/artic\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/cde.nus.edu.sg\/artic\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/cde.nus.edu.sg\/artic\/wp-json\/wp\/v2\/users\/77"}],"replies":[{"embeddable":true,"href":"https:\/\/cde.nus.edu.sg\/artic\/wp-json\/wp\/v2\/comments?post=14253"}],"version-history":[{"count":4,"href":"https:\/\/cde.nus.edu.sg\/artic\/wp-json\/wp\/v2\/pages\/14253\/revisions"}],"predecessor-version":[{"id":14594,"href":"https:\/\/cde.nus.edu.sg\/artic\/wp-json\/wp\/v2\/pages\/14253\/revisions\/14594"}],"wp:attachment":[{"href":"https:\/\/cde.nus.edu.sg\/artic\/wp-json\/wp\/v2\/media?parent=14253"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
