This property is used in a wide variety of industries and devices, such as the manufacture of modern electric motors, household and computer equipment, and other appliances. Traditional methods of manufacturing permanent magnets only allow for the creation of large products, and usually have two poles \u2013 one north and one south.<\/p>\n<p>Creating complex and small magnets is not an easy task, scientifically and technically, however, as it turns out, one of the most promising ways to create complex-shaped p<a href=\"https:\/\/facfox.com\/news\/topics\/art\" target=\"_blank\" rel=\"noopener\">art<\/a>s from magnetically hard materials is with <a href=\"https:\/\/facfox.com\/service\/3d-printing-service\" target=\"_blank\" rel=\"noopener\">3D printing<\/a>. Ural scientists have managed to determine the optimal parameters for the <a href=\"https:\/\/facfox.com\/service\/3d-printing-service\" target=\"_blank\" rel=\"noopener\">3D printing<\/a> of permanent magnets using selective laser sintering \u2013 and magnetic powder.<\/p>\n<p><a href=\"https:\/\/facfox.com\/service\/3d-printing-service\" target=\"_blank\" rel=\"noopener\">3D printing<\/a> makes it possible to change the internal properties of the magnet at almost all stages of production. For example, to change the chemical composition of the compound, the degree of spatial orientation of crystallites and crystallographic texture, and to influence the coercivity (resistance to demagnetization).<\/p>\n<div style=\"background-color: #eaeaea7a;padding: 15px 30px;align-items: center;border-radius: 4px;margin-top: 1em;margin-bottom: 1em\">\n<div style=\"flex: 1;padding-right: 30px\">\n<h4 style=\"margin-bottom: 14px\">Manufacturing on Demand<\/h4>\n<div>Online manufacturing service that meets your most stringent requirements.

Image: Oksana Meleshchuk   <\/p>\n<p>\u201cMaking small magnets is a difficult task. Now they are created only by cutting a large magnet into pieces, because of the <a href=\"https:\/\/facfox.com\/news\/topics\/mechanics\" target=\"_blank\" rel=\"noopener\">mechanic<\/a>al processing about half of the used material turns into garbage. Also, cutting introduces a lot of defects in the near-surface layer, which causes the properties of the magnet to deteriorate enormously. Additive technologies allow to avoid this and make complex magnets, for example, with one north pole and two spatially separated south poles, or a magnet with five south poles and five north poles at once. Such configurations are necessary for pacemakers, where it is only possible to assemble the rotor for an electric motor from separate magnets under a microscope,\u201d explained Dmitry Neznakhin, Associate Professor at the Dep<a href=\"https:\/\/facfox.com\/news\/topics\/art\" target=\"_blank\" rel=\"noopener\">art<\/a>ment of Magnetism and Magnetic Nanomaterials and Researcher at the Section of Solid State Magnetism at UrFU.<\/p>\n<p>The Russian scientists have already succeeded in producing thin (about one millimeter), permanent magnets whose properties are similar to those of industrially-produced magnets. The base that was used was a powder containing samarium, zirconium, iron, and titanium. The compound has suitable characteristics for permanent magnets, but traditional manufacturing methods deprive the compound of most of its properties. Therefore, the scientists decided to see if the properties could be preserved through <a href=\"https:\/\/facfox.com\/service\/3d-printing-service\" target=\"_blank\" rel=\"noopener\">3D printing<\/a> technology.<\/p>\n<p>\u201cWhen creating permanent magnets based on these compounds using traditional methods, the properties of the finished products are far from the theoretically predicted ones. We found that when sintering a sample, adding a fusible powder from an alloy of samarium, copper, and cobalt allows the magnetic characteristics of the main magnetic powder to be retained. This alloy melts at temperatures lower than the properties of the main alloy change, which is why the final material retains its coercive force and density,\u201d added Dmitry Neznakhin.<\/p>\n<p>At the moment, the scientists are establishing the basic laws of formation of the microstructure and magnetic properties of hard magnetic materials, and are determining which magnetic materials can be used to manufacture permanent magnets using the <a href=\"https:\/\/facfox.com\/service\/sls-rapid-prototyping-services\" target=\"_blank\" rel=\"noopener\">SLS<\/a>. This includes testing how the sintering method affects the properties of another known base for magnets \u2013 an alloy of neodymium, iron, and boron. The next stage of the work will be the production of bulk permanent magnets suitable for practical <a href=\"https:\/\/facfox.com\/news\/topics\/insights\/applications\" target=\"_blank\" rel=\"noopener\">application<\/a>s.
