DMLS allows for the creation of highly detailed, complex metal components with exceptional precision, ideal for producing intricate geometries and fine features that are difficult to achieve through traditional manufacturing methods.<\/p>\n\n\n\n<p>To fully harness the capabilities of DMLS, it is crucial to avoid common mistakes by following specific design guidelines and best practices, such as incorporating adequate support structures, determining optimal wall thicknesses, and maintaining proper distances between features.&nbsp;<\/p>\n\n\n    <aside class=\"article-content-aside\">\r\n        <a href=\"https:\/\/xometry.pro\/en-tr\/articles\/3d-printing-dmls-overview\/\" class=\"aside-image sidebar__aside-image\"><img decoding=\"async\" src=\"https:\/\/xometry.pro\/wp-content\/uploads\/2023\/09\/2-DMLS-Aluminum-AlSi10Mg-Front-scaled.jpg\" alt=\"\"><\/a><a href=\"https:\/\/xometry.pro\/en-tr\/articles\/3d-printing-dmls-overview\/\" class=\"aside-link\">Direct Metal Laser Sintering (DMLS) 3D printing: Technology overview<\/a>    <\/aside>\r\n    \n\n    <section class=\"article-author-block\">\r\n        <div class=\"article-content-wrapper\">\r\n            <div class=\"author-block\">\r\n                                        <div class=\"author-info\">\r\n                            <h4 class=\"author-name\">Nikolaus Mroncz<\/h4>\r\n                            <p class=\"author-position\">Head of Sales Engineering<\/p>\r\n                        <\/div>\r\n                                    <\/div>\r\n                <div class=\"quote-block\" style=\"border-color: #0E6AED;\">\r\n                    <p>One of the main things to watch out for with DMLS is avoiding bulky parts. The more volume you&#8217;re printing, the more you&#8217;re likely to run into problems like shrinkage and deformation, which can throw off accuracy. If the &#8216;melt pool&#8217; gets too big, you can end up with swelling, and even machine failures, like when the recoater crashes. This isn&#8217;t just an issue with DMLS\u2014it\u2019s something to keep in mind for MJF and SLS too.<\/p>\n                <\/div>\r\n        <\/div>\r\n    <\/section>\r\n\n\n\n<p>These considerations, among others, will be discussed in detail in this guide to help you optimize your designs for successful DMLS 3D printing.<\/p>\n\n\n<h2 class=\"wp-block-heading\" id=\"h-1-misuse-or-overuse-support-structures\"><strong>#1 Misuse or Overuse Support Structures<\/strong><\/h2>\n\n\n<p>In Direct Metal Laser Sintering (DMLS), each printed layer relies on the previous layers for support. For geometries like overhangs, arches, and surfaces angled greater than 30\u00b0, additional support structures are necessary to prevent warping, secure parts to the build platform, and maintain accuracy during printing. These supports, although crucial, increase material usage, build time, and costs, and must be removed in post-processing.<\/p>\n\n\n\n<p><strong>Rule of thumb:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Design self-supporting features<\/strong> with angles of 45\u00b0 or more to reduce the need for support structures.<\/li>\n\n\n\n<li><strong>Minimize the need for supports<\/strong> by using angles of 30\u00b0 or less and adding fillets or chamfers on corners.<\/li>\n\n\n\n<li><strong>Provide adequate support<\/strong> for horizontal surfaces, large holes, and overhangs to prevent part movement during printing, which can cause inaccuracies or machine crashes.<\/li>\n<\/ul>\n\n\n    <aside class=\"article-content-aside\">\r\n        <a href=\"https:\/\/xometry.pro\/en-tr\/topic\/optimizing-part-orientation-for-3d-printing\/\" class=\"aside-image sidebar__aside-image\"><img decoding=\"async\" src=\"https:\/\/xometry.pro\/wp-content\/uploads\/2023\/11\/community-icon-1.svg\" alt=\"\"><\/a><a href=\"https:\/\/xometry.pro\/en-tr\/topic\/optimizing-part-orientation-for-3d-printing\/\" class=\"aside-link\">Topic: Optimizing part orientation for 3D printing<\/a>    <\/aside>\r\n    \n\n\n<figure class=\"wp-block-image size-large is-resized\"><div class=\"wp-block-image__wrap\"><img decoding=\"async\" width=\"992\" height=\"1024\" src=\"https:\/\/xometry.pro\/wp-content\/uploads\/2024\/10\/support-structures-992x1024.png\" alt=\"\" class=\"wp-image-57857\" style=\"max-width:400px\" srcset=\"https:\/\/xometry.pro\/wp-content\/uploads\/2024\/10\/support-structures-992x1024.png 992w, https:\/\/xometry.pro\/wp-content\/uploads\/2024\/10\/support-structures-291x300.png 291w, https:\/\/xometry.pro\/wp-content\/uploads\/2024\/10\/support-structures-768x793.png 768w, https:\/\/xometry.pro\/wp-content\/uploads\/2024\/10\/support-structures-1488x1536.png 1488w, https:\/\/xometry.pro\/wp-content\/uploads\/2024\/10\/support-structures-1984x2048.png 1984w, https:\/\/xometry.pro\/wp-content\/uploads\/2024\/10\/support-structures.png 2000w\" sizes=\"(max-width: 992px) 100vw, 992px\" \/><a class=\"wp-block-image__fancy-box-button\" href=\"https:\/\/xometry.pro\/wp-content\/uploads\/2024\/10\/support-structures.png\" data-fancybox=\"gallery-22357\" data-caption=\"\" aria-label=\"Open full image\"><img src=\"https:\/\/xometry.pro\/wp-content\/uploads\/2024\/10\/support-structures.png\" class=\"wp-block-image__fancy-box-button-thumbnail wp-post-image\" alt=\"\" loading=\"lazy\" decoding=\"async\"><svg class=\"wp-block-image__fancy-box-button-icon\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"18\" height=\"18\" viewBox=\"0 0 18 18\" fill=\"none\" aria-hidden=\"true\">\r\n               <path d=\"M0 2V6H2V2H6V0H2C0.895 0 0 0.895 0 2ZM2 12H0V16C0 17.105 0.895 18 2 18H6V16H2V12ZM16 16H12V18H16C17.105 18 18 17.105 18 16V12H16V16ZM16 0H12V2H16V6H18V2C18 0.895 17.105 0 16 0Z\" fill=\"#092C47\"\/>\r\n             <\/svg><\/a><\/div><\/figure>\n\n\n<h2 class=\"wp-block-heading\" id=\"2-apply-inconsistent-or-insufficient-wall-thicknesses\"><strong>#2 Apply Inconsistent or Insufficient Wall Thicknesses<\/strong><\/h2>\n\n\n<p>Wall thicknesses in metal 3D printing can vary based on material choice, part orientation, and desired resolution.

Additionally, factors like internal stresses during printing, the need for support structures, and part geometry can cause deviations in tolerances and affect flatness. If your design requires strict flatness, DMLS might not be the most suitable option.<\/span><\/p>\n\t<\/div>\r\n<\/div>\r\n<style>\r\n\t.custom-table-block table{\r\n\t\theight: initial!important;\r\n\t}\r\n\t.search-input-wrapper{\r\n\t\tposition: relative;\r\n\t\tmargin-bottom: 24px;\r\n\t}\r\n\t.search-input-wrapper svg{\r\n\t\tposition: absolute;\r\n\t\ttop:50%;\r\n\t\tleft:12px;\r\n\t\ttransform: translateY(-50%);\r\n\t}\r\n\t.table-search-input{\r\n\t\tpadding: 0 0 0 40px;\r\n\t\tborder:1px solid #C1CAD1;\r\n\t\theight: 44px;\r\n\t\twidth: 201px;\r\n\t\tcolor:#092C47;\r\n\t\tfont-family: Open Sans;\r\n\t\tfont-size: 16px;\r\n\t\tfont-weight: 400;\r\n\t\tline-height: 24px;\r\n\t\tletter-spacing: 0em;\r\n\t\ttext-align: left;\r\n\t}\r\n\t.table-search-input::placeholder{\r\n\t\tcolor:#092C47;\r\n\t}\r\n\t\r\n\t.custom-table-block thead th{\r\n\t\ttext-align: left;\r\n\t\twhite-space:nowrap;\r\n\t}\r\n\t\r\n\t.custom-table-block thead{\r\n\t\tmargin-bottom: 14px;\r\n\t}\r\n\r\n\t.custom-table-block tbody tr:nth-child(odd){\r\n\t\tbackground-color: #F6F9FF;\r\n\t}\r\n\r\n\t.custom-table-block tbody, .custom-table-block thead, .custom-table-block tr, .custom-table-block td, .custom-table-block th{\r\n\t\theight: initial!important;\r\n\t}\r\n\t\r\n\t.custom-table-block tbody td{\r\n\t\tcolor:#092C47;\r\n\t\tfont-family: Open Sans;\r\n\t\tfont-size: 16px;\r\n\t\tfont-weight: 400;\r\n\t\tline-height: 24px;\r\n\t\tletter-spacing: 0em;\r\n\t\ttext-align: left;\r\n\t\tpadding: 7px;\r\n\t}\r\n\t\r\n\t.custom-table-block thead th{\r\n\t\tfont-family: Open Sans;\r\n\t\tfont-size: 16px;\r\n\t\tfont-weight: 700;\r\n\t\tline-height: 24px;\r\n\t\tletter-spacing: 0em;\r\n\t\ttext-align: left;\r\n\t\tcolor:#092C47;\r\n\t\tposition: relative;\r\n\t}\r\n\t.custom-table-block thead th:after{\r\n\t\tcontent:\"\";\r\n\t\tdisplay: inline-block;\r\n\t\tbackground-image: url(\"data:image\/svg+xml,%3Csvg width='12' height='8' viewBox='0 0 12 8' fill='none' xmlns='http:\/\/www.w3.org\/2000\/svg'%3E%3Cpath d='M10.585 0.585938L6 5.17094L1.415 0.585938L0 2.00094L6 8.00094L12 2.00094L10.585 0.585938Z' fill='%23476175'\/%3E%3C\/svg%3E%0A\");\r\n\t\tmargin-left: 8px;\r\n\t\tbackground-position: center center;\r\n\t\tbackground-size: 12px 7.5px;\r\n\t\tbackground-repeat: no-repeat;\r\n\t\twidth: 24px;\r\n\t\theight: 12px;\r\n\t}\r\n\t.custom-table-block{\r\n\t\tmargin: 20px 0;\t\r\n\t}\r\n\t.custom-table-block .table-wrapper{\r\n\t\twidth: 100%;\r\n\t\toverflow-x: auto;\r\n\t}\r\n\t@media(max-width: 768px){\r\n\t\t\/* .custom-table-block tbody td{\r\n\t\t\twhite-space: nowrap;\r\n\t\t} *\/\r\n\t\t.custom-table-block .table-wrapper{\r\n\t\t\tmax-width: calc(100vw - 16px);\r\n\t\t}\r\n\t}\r\n<\/style>\r\n\n\n<h2 class=\"wp-block-heading\" id=\"get-your-custom-metal-3d-printed-parts-at-xometry\"><strong>Get Your Custom Metal 3D Printed Parts at Xometry<\/strong><\/h2>\n\n\n<p>At Xometry, we offer on-demand <a href=\"https:\/\/xometry.com.tr\/en\/3d-printing-dmls\/\" target=\"_blank\" rel=\"noreferrer noopener\">DMLS 3D printing services<\/a> across a range of metal alloys through our vast network of manufacturers.
