This trend stems from several main factors: <\/p>\n\n<p class=\"has-white-color has-primary-background-color has-text-color has-background has-link-color wp-elements-2a2cf35da1b79b81f99a65b239c1afc7 wp-block-paragraph\"><strong>Lower costs of printers and materials<\/strong> &#8211; a decrease in the costs of printers and materials used in SLS technology makes the technology more accessible for medium and small companies.<\/p>\n\n<p class=\"has-white-color has-primary-background-color has-text-color has-background has-link-color wp-elements-93b53caab1cbc5b5cca38e9d72327940 wp-block-paragraph\"><strong>Improvement in printing<\/strong> materials &#8211; Continuous development of new printing materials, especially combinations of nylon reinforced with fibers such as carbon fiber and glass fiber, makes SLS more attractive for applications in various industries, such as automotive and aviation.<\/p>\n\n<p class=\"has-white-color has-primary-background-color has-text-color has-background has-link-color wp-elements-cc05e991d4590bc08ccffefd68befc61 wp-block-paragraph\"><strong>Expanding Functional Uses<\/strong> \u2013 The use of SLS for the production of final parts is steadily increasing, especially in applications that require high durability and precision, as well as for parts with complex geometries that cannot be easily produced by traditional manufacturing methods.<\/p>\n\n<p class=\"has-white-color has-primary-background-color has-text-color has-background has-link-color wp-elements-f474ad377caf9323b7ae2a721df4540f wp-block-paragraph\"><strong>Increase in needs for fast and customized production<\/strong> &#8211; the increase in the trend of production on demand and small series also contributes to the growth of SLS, because it provides customized parts at high speed and with excellent quality.<\/p>\n\n<p class=\"has-white-color has-primary-background-color has-text-color has-background has-link-color wp-elements-e5a3452ffe874cfdc9fa916a32c4ba8f wp-block-paragraph\"><strong>Improvement in technology capabilities<\/strong> &#8211; the scientific and technological improvements in the printing processes and the ability to control the mechanical characteristics of the printed parts increase the trust and demand for technology in the medical, aviation, electronics and other industries.<\/p>\n\n<ol class=\"wp-block-list\">\n<li><\/li>\n<\/ol>\n\n<p class=\"has-white-color has-primary-background-color has-text-color has-background has-link-color wp-elements-45a17eba831bd326708d908b8e818e00 wp-block-paragraph\">Estimates show that SLS technology is expected to continue to grow by approximately 15-20% per year, at a relatively high rate compared to traditional printing technologies, and to gain momentum as the technology continues to improve and becomes a key tool for flexible and accurate production.<\/p>\n\n<h2 class=\"wp-block-heading has-white-color has-primary-background-color has-text-color has-background has-link-color wp-elements-08b604ca21b6c0faaa9b0948ec65afab\" id=\"&#x5DB;&#x5D9;&#x5E6;&#x5D3;-&#x5E4;&#x5D5;&#x5E2;&#x5DC;&#x5EA;-&#x5D4;&#x5D3;&#x5E4;&#x5E1;&#x5EA;-&#x5EA;&#x5DC;&#x5EA;-&#x5DE;&#x5D9;&#x5DE;&#x5D3;-sls-1\">How does SLS printing work?<\/h2>\n\n<figure class=\"wp-block-image size-full\"><a href=\"http:\/\/beyond3d.co.il\/wp-content\/uploads\/SLS-&#x5D4;&#x5E1;&#x5D1;&#x5E8;.png\"><img decoding=\"async\" src=\"http:\/\/beyond3d.co.il\/wp-content\/uploads\/SLS-&#x5D4;&#x5E1;&#x5D1;&#x5E8;.png\" alt=\"SLS printing explained\" class=\"wp-image-18546\"\/><\/a><\/figure>\n\n<p class=\"has-white-color has-primary-background-color has-text-color has-background has-link-color wp-elements-07cd284cd4dd85bdee1b8fcf1f21696d wp-block-paragraph\">1) Heating the cell &#8211; a preliminary step for printing, depending on the size of the SLS printer cell takes between 1 and 3 hours.<br\/>Large SLS printer about 3 hours, small SLS printer about 1 hour.<\/p>\n\n<p class=\"has-white-color has-primary-background-color has-text-color has-background has-link-color wp-elements-0d260c93647b25b6c79977537d9b6d31 wp-block-paragraph\">2) Printing &#8211; the powder is spread in a thin layer on a platform inside the construction chamber. The printer preheats the powder to a temperature just below the raw material&#8217;s melting point, making it easy for the laser to raise the temperature of specific areas of the powder bed while following the model to solidify a part. The laser scans a cross section of the 3D model. It fuses the particles together mechanically to form one solid part. The unfused powder supports the part during printing and eliminates the need for dedicated support structures. The platform is then lowered one layer into the build chamber, typically between 50 and 200 microns, and the process is repeated for each layer until the parts are complete.<\/p>\n\n<p class=\"has-white-color has-primary-background-color has-text-color has-background has-link-color wp-elements-49c86d7f6e0ce27d46734f9798bfba32 wp-block-paragraph\">3) Cooling- After printing, the build cell needs to cool slightly inside the print case and then outside the printer to ensure optimal mechanical properties and prevent distortion of the parts.<br\/>In small printers about 3 hours, large ones over 6 hours.<\/p>\n\n<p class=\"has-white-color has-primary-background-color has-text-color has-background has-link-color wp-elements-56afcac6a19bf7b1c60628983ca7545f wp-block-paragraph\">4) After processing &#8211; the finished parts must be removed from the construction chamber, separated and cleaned of excess powder. The powder can be recycled and the printed parts can be further processed by media blasting or media casting. (Printed SLS parts have a slightly grainy surface finish, but with almost no visible layer lines. For a smoother surface finish, it is recommended to work with media spraying.<\/p>\n\n<p class=\"has-white-color has-primary-background-color has-text-color has-background has-link-color wp-elements-4bb4315fc2fcae50441d4d56be7af944 wp-block-paragraph\">SLS printing requires a high level of precision and tight control throughout the entire printing process. The temperature of the powder together with the (incomplete) parts must be controlled within 2\u00b0C during the three stages of preheating, melting and storage before removal to minimize heat-induced distortions and stresses. <\/p>\n\n<h2 class=\"wp-block-heading has-white-color has-primary-background-color has-text-color has-background has-link-color wp-elements-ed5fb6ae0f761b0da69457c274d89541\" id=\"&#x5D7;&#x5D5;&#x5DE;&#x5E8;-&#x5D2;&#x5DC;&#x5DD;\">Raw materials in SLS printing:<\/h2>\n\n<p class=\"has-white-color has-primary-background-color has-text-color has-background has-link-color wp-elements-fec2ecf3b4cb1bd1dc0dbd650b044424 wp-block-paragraph\">There are a variety of SLS printing materials such as:<br\/> <strong>Nylon 12 (PA12)<\/strong> &#8211; the most common material in SLS printing, a durable, flexible and easy-to-process material, suitable for functional parts and prototypes.<br\/> Excellent combination of strength, rigidity and chemical resistance.<br\/> Excellent for general uses such as end products, connecting devices and industrial parts.<br\/> Usually with white powder and dyeing with fabric dyeing materials is required to paint the part from the inside.<br\/> In PA12, the flow and absorption are relatively high, in printers it is simpler sometimes to print with black in advance (so it is easier for the laser to burn the material) and no finishing work is required in painting.<\/p>\n\n<figure class=\"wp-block-image size-full\"><a href=\"http:\/\/beyond3d.co.il\/wp-content\/uploads\/&#x5D4;&#x5D3;&#x5E4;&#x5E1;&#x5EA;-SLS-&#x5D7;&#x5DC;&#x5E7;&#x5D9;&#x5DD;.png\"><img decoding=\"async\" src=\"http:\/\/beyond3d.co.il\/wp-content\/uploads\/&#x5D4;&#x5D3;&#x5E4;&#x5E1;&#x5EA;-SLS-&#x5D7;&#x5DC;&#x5E7;&#x5D9;&#x5DD;.png\" alt=\"SLS printing parts\" class=\"wp-image-18552\"\/><\/a><\/figure>\n\n<p class=\"has-white-color has-primary-background-color has-text-color has-background has-link-color wp-elements-4011ace1afe8a57a85ed85b5edd4294f wp-block-paragraph\"><strong>Nylon 11 (PA11)<\/strong> &#8211; a more flexible material than PA12 and resistant to mechanical damage, especially suitable for parts that require higher resistance such as pipes and flexible bodies.<br\/> Occupies a smaller percentage than nylon 12 but is common in applications that require increased flexibility and durability.<\/p>\n\n<p class=\"has-white-color has-primary-background-color has-text-color has-background has-link-color wp-elements-6e47a1d18d987b5f4efdd7f15044691b wp-block-paragraph\"><strong>Nylon reinforced with glass fibers or carbon fibers<\/strong> &#8211; a combination of nylon with reinforced materials to improve strength and rigidity.

format (STL, OBJ or 3MF). Each SLS printer includes software with fine-tuned print settings that help you orient and arrange models, as well as estimate print times and lay out the digital model into layers for printing. After the setup is complete, the print preparation software sends the instructions to the printer via a wireless or cable connection.  <\/p>\n\n<h2 class=\"wp-block-heading has-white-color has-primary-background-color has-text-color has-background has-link-color wp-elements-eaebc7d3ac610729ab63eb75130e5db1\" id=\"&#x5D3;\">Highlights for product design in SLS printing<\/h2>\n\n<p class=\"has-white-color has-primary-background-color has-text-color has-background has-link-color wp-elements-f092275fa26c0ccfe065fee2cc969b2d wp-block-paragraph\">Wall thickness: This refers to the thickness in any direction on smooth walls or geometries. The minimum wall thickness allowed is 0.762 mm &#8211; 0.508 mm<br\/> When the thin wall is supported on both sides it can be thinner and without support a little thicker.<br\/> Gaps: This refers to the distance between two features. It is important to consider the channel spacing when designing 3D printed nylons because the sintering process can merge two features that do not relate to the channel spacing. We recommend minimum channel gap sizes of 0.762mm.   <br\/>Fringe: Designs that have a feature such as a counter hole. Your dimension may drop below the minimum feature size at the far end of the hole. This may result in a truncated or rounded feature that is not generated properly. Similar to the wall thickness, we recommend making sure the measurements are at least 0.762mm &#8211; 0.508mm   <\/p>\n\n<p class=\"has-white-color has-primary-background-color has-text-color has-background has-link-color wp-elements-24ff1eeab5c742d3d1704061c6663cf4 wp-block-paragraph\">After all pre-printing tests are completed, the device is ready to print.

The build cell can then be removed and a new cell inserted to run another print. <\/p>\n\n<p class=\"has-white-color has-primary-background-color has-text-color has-background has-link-color wp-elements-25a6744a536dbfe31d379469a12dca95 wp-block-paragraph\">Then, the build chamber with the printer parts needs to be further cooled before post-processing to ensure the optimal mechanical properties and avoid distortion of the parts. This may take up to half the printing time. <br\/>After the build has cooled, the finished parts can be removed from the build chamber and extracted from the unbridled powder.<\/p>\n\n<p class=\"has-white-color has-primary-background-color has-text-color has-background has-link-color wp-elements-63ca59b44fea5c082a73b3766cc225c7 wp-block-paragraph\">After the parts are extracted, media spraying is a critical step for fully dusting SLS 3D printed parts and achieving a smooth, dust-free finish. This will remove the loose powder and clean the semi-filtered surface armor from your printed parts. <\/p>\n\n<h2 class=\"wp-block-heading has-white-color has-primary-background-color has-text-color has-background has-link-color wp-elements-7deda0c42e5cde37a0360d02c5683e46\" id=\"&#x5DC;\">In conclusion<\/h2>\n\n<p class=\"has-white-color has-primary-background-color has-text-color has-background has-link-color wp-elements-567c9b6c008bd333791cfc7ac23e2917 wp-block-paragraph\">3D printing with SLS technology (selective laser sintering) offers an advanced and efficient solution for the production of precise and durable parts while allowing the design of complex geometries without additional support structures. This technology is particularly suitable for rapid prototyping and small, customized production series, and provides parts with mechanical durability similar to that of cast parts. <br\/>The technology occupies between 10-15% of all 3D printing jobs on the market.<\/p>\n\n<p class=\"has-white-color has-primary-background-color has-text-color has-background has-link-color wp-elements-e681c301cdc5c3780abd36d8383344fb wp-block-paragraph\">When designing parts for SLS printing, it is recommended to maintain a minimum wall thickness of 0.5-0.8 mm and gaps of at least 0.76 mm between adjacent features, to maintain accuracy and prevent unwanted blending between features.<\/p>\n\n<p class=\"has-white-color has-primary-background-color has-text-color has-background has-link-color wp-elements-53c3433cbf6c99fee3fe69800b0ea613 wp-block-paragraph\">SLS printing percentage deviation ranges from \u00b10.3% to \u00b10.5% depending on part size and print settings, with small parts benefiting from higher accuracy around \u00b10.1mm.
