In DMLS, however, metal powders are used instead of plastic powders to create metal parts that can be used both for functional prototypes and production parts.\u00a0<\/p>\n\n\n\n<p>Direct metal laser sintering technology is similar to Selective laser melting (SLM) technology, but the difference between both processes is the temperature used for metal powder fusion. SLM, as the name suggests, heats the metal powder until it fully melts into a liquid. DMLS does not melt the metal powder but sinters heat particles enough so that their surfaces weld together. Anyway, both terms (SLM and DMLS) are often used interchangeably in the 3D printing industry.<\/p>\n\n\n<h2 class=\"wp-block-heading\" id=\"h-how-dmls-works\"><strong><strong>How DMLS Works?<\/strong><\/strong><\/h2>\n\n\n<p>Direct Metal Laser Sintering (DMLS) is an additive manufacturing process that builds fully dense metal parts layer by layer by selectively fusing metal powder using a laser. The process includes four main stages: design preparation, powder spreading, laser sintering, and post-processing.<\/p>\n\n\n\n<iframe width=\"700\" height=\"394\" src=\"https:\/\/www.youtube.com\/embed\/FxzFzbi0wF4?si=qp4cS9L0mSYN-vAJ&amp;start=32\" title=\"YouTube video player\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe>\n\n\n\n<p>Watch: How DMLS Works \u2014 Step-by-Step Metal 3D Printing Explained<\/p>\n\n\n<h3 class=\"wp-block-heading\" id=\"1-design-preparation\"><strong>1.

DMLS full potential can be seen when engineers design parts with complex geometries, such as integrated fastening features, long and narrow channels or mesh structures. DMLS facilitates all-in-one assemblies that reduce the number of parts, assembly time and rate for failures by combining multiple parts into a single design.<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<div style=\"height:31px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<figure class=\"wp-block-image size-full\"><div class=\"wp-block-image__wrap\"><img decoding=\"async\" width=\"2560\" height=\"1807\" src=\"https:\/\/xometry.pro\/wp-content\/uploads\/2024\/02\/3dprinting-metal-dmls-scaled.jpg\" alt=\"Prototype example built with DMLS 3D printing\" class=\"wp-image-31377\" srcset=\"https:\/\/xometry.pro\/wp-content\/uploads\/2024\/02\/3dprinting-metal-dmls-scaled.jpg 2560w, https:\/\/xometry.pro\/wp-content\/uploads\/2024\/02\/3dprinting-metal-dmls-300x212.jpg 300w, https:\/\/xometry.pro\/wp-content\/uploads\/2024\/02\/3dprinting-metal-dmls-1024x723.jpg 1024w, https:\/\/xometry.pro\/wp-content\/uploads\/2024\/02\/3dprinting-metal-dmls-768x542.jpg 768w, https:\/\/xometry.pro\/wp-content\/uploads\/2024\/02\/3dprinting-metal-dmls-1536x1084.jpg 1536w, https:\/\/xometry.pro\/wp-content\/uploads\/2024\/02\/3dprinting-metal-dmls-2048x1446.jpg 2048w\" sizes=\"(max-width: 2560px) 100vw, 2560px\" \/><a class=\"wp-block-image__fancy-box-button\" href=\"https:\/\/xometry.pro\/wp-content\/uploads\/2024\/02\/3dprinting-metal-dmls-scaled.jpg\" data-fancybox=\"gallery-11584\" data-caption=\"Prototype example built with DMLS 3D printing\" aria-label=\"Open full image\"><img src=\"https:\/\/xometry.pro\/wp-content\/uploads\/2024\/02\/3dprinting-metal-dmls-scaled.jpg\" 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><figcaption class=\"wp-element-caption\">Prototype example built with DMLS 3D printing<\/figcaption><\/figure>\n<\/div>\n<\/div>\n\n\n<h3 class=\"wp-block-heading\" id=\"h-quick-turnaround-time\">Quick Turnaround Time<\/h3>\n\n\n<p>The normal conventional process requires a lot of time to set the tool up before manufacturing which involves jigs and fixtures whereas, in DMLS, the part can be printed on-demand without any ramp \u00adup or tooling, resulting in shorter lead time compared to CNC machining. The combination of the reduced lead time and the efficient prototyping process reduces the turnaround time. This is one of the biggest advantages of DMLS.<\/p>\n\n\n<h3 class=\"wp-block-heading\" id=\"h-dmls-use-lightweight-and-durable-components\">DMLS Use Lightweight and Durable Components<\/h3>\n\n\n<p>Parts manufactured from super alloys like Inconel 718, AlSi10Mg and Cobalt-chromium, are known to be lightweight compared to their conventionally machined counterparts. As an example, <a href=\"https:\/\/www.youtube.com\/watch?v=rMzVSbNebCg&amp;ab_channel=GEAviation\" target=\"_blank\" rel=\"noreferrer noopener\">GE\u2019s renowned 3D printed fuel nozzles<\/a> for its LEAP family of engines used to be made from 20 discrete parts coming from independent suppliers but using direct metal laser sintering (DMLS) resulted in a single-piece component which is 25 per cent lighter and five times stronger than the original parts.<\/p>\n\n\n<h3 class=\"wp-block-heading\" id=\"h-dmls-allows-less-wastage\">DMLS Allows Less Wastage<\/h3>\n\n\n<p>Metal powders that are untouched by the laser can be recycled and reused. Powder recycling also results in reduced prices. The waste produced is significantly less compared to a conventional process like CNC where a lot of waste is generated in the form of chips that are produced as a result of machining a metal according to a required design from a metal block and are very tough to recycle.<\/p>\n\n\n<h2 class=\"wp-block-heading\" id=\"h-considerations-about-dmls-technology\">Considerations About DMLS Technology<\/h2>\n\n\n<p>Apart from the advantages of DMLS, there are a few considerations. The biggest competitor to DMLS would be the traditional machining technologies like CNC.<\/p>\n\n\n<h3 class=\"wp-block-heading\" id=\"h-dmls-needs-support-structures\">DMLS Needs Support Structures<\/h3>\n\n\n<p>Since DMLS belongs to the powder-based fusion category, support structures are inevitable and need to be removed in the end with the help of post-processing. During post-processing, the metal printed part is treated similar to a raw metal part manufactured conventionally and which means the part manufactured by DMLS is not ready to use and needs some work.<\/p>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-9d6595d7 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\"><h3 class=\"wp-block-heading\" id=\"h-dmls-parts-have-a-grainy-surface-finish\">DMLS Parts Have a Grainy Surface Finish<\/h3>\n\n\n<p>DMLS printed surfaces won\u2019t be as smooth as surfaces with CNC machining, and that it won\u2019t be as easy to produce the desired surface textures. If post-processing needs to be done to enhance the finish and improve the aesthetics, the cost also increases accordingly.<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<figure class=\"wp-block-image size-large is-resized\"><div class=\"wp-block-image__wrap\"><img decoding=\"async\" width=\"1024\" height=\"789\" src=\"https:\/\/xometry.pro\/wp-content\/uploads\/2023\/09\/Grainy-structure-of-DMLS-1024x789.jpg\" alt=\"Grainy structure of DMLS\" class=\"wp-image-1815\" style=\"max-width:295px;max-height:227px\" srcset=\"https:\/\/xometry.pro\/wp-content\/uploads\/2023\/09\/Grainy-structure-of-DMLS-1024x789.jpg 1024w, https:\/\/xometry.pro\/wp-content\/uploads\/2023\/09\/Grainy-structure-of-DMLS-300x231.jpg 300w, https:\/\/xometry.pro\/wp-content\/uploads\/2023\/09\/Grainy-structure-of-DMLS-768x592.jpg 768w, https:\/\/xometry.pro\/wp-content\/uploads\/2023\/09\/Grainy-structure-of-DMLS.jpg 1440w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><a class=\"wp-block-image__fancy-box-button\" href=\"https:\/\/xometry.pro\/wp-content\/uploads\/2023\/09\/Grainy-structure-of-DMLS.jpg\" data-fancybox=\"gallery-11584\" data-caption=\"Grainy structure of DMLS\" aria-label=\"Open full image\"><img src=\"https:\/\/xometry.pro\/wp-content\/uploads\/2023\/09\/Grainy-structure-of-DMLS.jpg\" 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><figcaption class=\"wp-element-caption\">Grainy structure of DMLS<\/figcaption><\/figure>\n<\/div>\n<\/div>\n\n\n<h3 class=\"wp-block-heading\" id=\"h-expensive-serial-production-of-dmls-parts\">Expensive Serial Production of DMLS Parts<\/h3>\n\n\n<p>Mass production is still a huge deciding factor across the industries and this is where DMLS&nbsp;lags behind compared to traditional techniques and the speed at which a 3D printer can assemble an object is no match to the conventional assembly line. Hence, DMLS is mainly recommended for a unit to a small batch.<\/p>\n\n\n<h3 class=\"wp-block-heading\" id=\"h-limited-material-selection\">Limited Material Selection<\/h3>\n\n\n<p>Generally, for metal 3D printing, the material selection is less, which can be a limiting factor when specific materials are needed for the required part and must be taken into consideration when deciding which technical properties you want your product to have.<\/p>\n\n\n<h3 class=\"wp-block-heading\" id=\"h-limited-build-volume\">Limited Build Volume<\/h3>\n\n\n<p>When a large part size is required, it\u2019s always better to go with CNC machining. For instance, the standard part size that is recommended with DMLS is up to 250 x 250 x 325 mm and for CNC machining, it is up to 2000 x 800 x 1000 mm. The size comparison clearly shows the inability of 3D printing to manufacture huge parts due to its limited powder bed size.&nbsp;<\/p>\n\n\n<h3 class=\"wp-block-heading\" id=\"h-shrinkage-and-limited-repeatability\">Shrinkage and Limited Repeatability<\/h3>\n\n\n<p>With DMLS it is very hard to produce identical parts because of the natural shrinkage process. For example, a part printed for the first time and a similar part printed for the 10th time will have at least 2% error in the vertical direction (Z-direction), leading to shrinkage. The Dimensional changes are caused as a result of a combination of three sources: thermal shrinkage, sintering shrinkage, and expansion arising because the metal particles fall during the sintering.<\/p>\n\n\n    <section class=\"article-slider-block\">\r\n        <div class=\"article-content-wrapper\">\r\n            <!-- Swiper -->\r\n            <div class=\"swiper mySwiper2
