However, before a printed green part can be transformed into a functional metal component, it must undergo a crucial process step: sintering.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This is precisely where one of the process\u2019s greatest challenges lies. During sintering, the parts shrink significantly and sometimes deform under their own weight. To still be able to produce precise parts with tight tolerances, Desktop Metal has developed the simulation software <a href=\"https:\/\/www.desktopmetal.com\/resources\/live-sinter\"><strong>Live Sinter\u2122<\/strong><\/a>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Why do Binder Jetting parts shrink?<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">After printing and the subsequent debinding process, the part is heated to a temperature just below the melting point of the metal powder.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">During this phase, the individual metal particles fuse together to form a dense structure. It is only at this point that the desired material properties\u2014such as strength, hardness, and density\u2014develop.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">At the same time, the voids between the metal particles close. As a result, the component shrinks. Typically, the linear shrinkage for metal components is about <strong>20 percent<\/strong>. This means that a component that will eventually measure 100 mm must initially be printed with a significant amount of excess material so that it reaches the desired final dimensions after sintering.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>The challenge: Every component shrinks differently<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The difficulty lies in the fact that shrinkage does not occur identically for every component. The behavior depends, among other things, on:<\/p>\n\n\n\n<ul class=\"wp-block-list ul-bullet\">\n<li>The geometry of the component<\/li>\n\n\n\n<li>The wall thickness<\/li>\n\n\n\n<li>The position in the sintering furnace<\/li>\n\n\n\n<li>The contact points<\/li>\n\n\n\n<li>The sintering parameters used<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Overhangs, thin-walled structures, asymmetrical geometries, and delicate lattice structures are particularly critical. These areas may undergo additional deformation or sagging during sintering. Predicting this shrinkage behavior is therefore one of the greatest challenges in industrial metal binder jetting.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/www.desktopmetal.com\/resources\/live-sinter\"><strong>Live Sinter\u2122<\/strong><\/a> <strong>: Virtual sintering before the actual sintering process<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">To solve this problem, <a href=\"https:\/\/am-pioneers.com\/en\/desktop-metal\/\">Desktop Metal<\/a> has developed the simulation software <a href=\"https:\/\/www.desktopmetal.com\/resources\/live-sinter\"><strong>Live Sinter\u2122<\/strong><\/a>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The software simulates a component\u2019s behavior during the sintering process even before printing.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It takes various physical factors into account, including:<\/p>\n\n\n\n<ul class=\"wp-block-list ul-bullet\">\n<li>Gravitational forces<\/li>\n\n\n\n<li>Frictional forces<\/li>\n\n\n\n<li>Material properties<\/li>\n\n\n\n<li>Thermal stresses<\/li>\n\n\n\n<li>Geometry-dependent deformations<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Based on these calculations, the software predicts how a component will deform during sintering.<\/p>\n\n\n\n<figure

Compensation Instead of Post-Processing Correction<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The real highlight of <a href=\"https:\/\/www.desktopmetal.com\/resources\/live-sinter\"><strong>Live Sinter\u2122<\/strong><\/a> is that the predicted deformations are specifically compensated for.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Instead of printing the part exactly to its target geometry, the software generates a deliberately deformed green part.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A typical example:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If an overhang sags downward during sintering, it is deliberately bent upward in the CAD model or in the green part.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">After sintering, the actual deformation compensates for this pre-deformation, so that the finished component achieves the desired geometry.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The simulation therefore uses what is known as a negative offset, which takes the expected deformations into account even before printing.<\/p>\n\n\n\n<figure

Mass Production: Printing, Sintering, Scanning<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For industrial mass production, a one-time simulation is often not enough.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">That is why dimensional accuracy is optimized through an iterative process:<\/p>\n\n\n\n<ul class=\"wp-block-list

incorporating actual measurement results, the simulation can be continuously improved.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This data-driven approach enables increasingly accurate predictions of shrinkage behavior and significantly reduces the effort required for physical iterations.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img data-recalc-dims=\"1\" decoding=\"async\"
