Scientists Use 3D Printing to Print Non-magnetic Metal Powders into Magnetic Alloys

Chile's government is considering phasing in a proposed ban on glacial mining to limit projects high in the Andes by some big copper companies. Chile's constitutional assembly has approved a proposal to ban mining in glaciers, protected areas, and areas vital to protecting the country's water system.

Chile's mining minister, Marcela Hernando, said about 20 mines had been identified in protected areas, some close to glaciers, including Codelco's El Teniente and Andina projects and Anglo American Plc's Los Bronces project.

The new measures for glaciers and other protected areas will put about a fifth of Chile's copper 3D printing metal powder prices are predicted to increase in the next few days.

Scientists at Skoltech University in Russia used a 3D printer to create an alloy of two materials whose composition ratios varied from one region of the sample to the next, and the resulting alloy had gradient magnetism, even though none of the initial materials were magnetic.
 
3D printing, a rapid prototyping method, is maturing for aircraft parts, medical implants and prosthetics, jewelry, custom shoes, and more. 
 
The main advantage of 3D printing is the ability to create objects with very complex shapes that are either too expensive to produce or completely impossible to produce using traditional casting, rolling, stamping, or machining methods. 3D printing speeds up prototyping time and offers greater flexibility in product personalization and the number of batches. Another significant advantage of 3D printing is its low waste. 
 
However, 3D printing has its limitations, requiring objects to be made entirely of homogeneous materials or mixtures. If the composition is different in different parts of the product, it is possible to obtain samples with changing characteristics. For example, A bar made of an alloy of two metals has A variable ratio of composition: one end starts with 100 percent of metal A, then 50 percent of each, then 100 percent of metal B, and so on. Thus, the properties of the obtained materials (including magnetic materials) can vary in a gradient, which makes them potentially useful for the manufacture of motor rotors, magnetic encoder strips, transformers, etc.
 
Skoltech scientists have researched and made such a kind of material, with the original ingredients A and B being two alloys: aluminum-bronze (copper, aluminum, and iron) and austenitic stainless steel (iron, chromium, and nickel, among others). Both alloys are paramagnetic, which means they are not attracted by magnets. But if you mix them, you get what's called a "soft magnetic material" ferromagnet, which is attracted to a permanent magnet. 
 
The researchers used the two paramagnetic materials to create a gradient alloy. They used an InssTekMX-1000 3D printer, which works by depositing material using directional energy action, feeding a powdery material, and melting it with a laser at the same time. The resulting materials exhibit varying degrees of ferromagnetic properties, depending on the proportions of the components. 
 
The researchers also theorized that the atomic structure of the alloy contributes to the expression of ferromagnetism in the alloy: although both materials have so-called face-centered cubic crystal structures, the combination results in a magnetic body-centered cubic structure. 
 
Gradient soft magnetic alloys can be used in mechanical engineering, for example, in the production of electric motors. The results also show that the method of surface treatment of materials using directional energy action can not only obtain gradient materials using 3D printing but also discover new alloys. The technology is efficient and suitable for the rapid production of large parts.

Where is the best place for humans to live in outer space? So far, the moon is more habitable in outer space, and it is likely to be turned into a planet. However, whether humans can live on the moon for a long time, these questions have always been lingering in everyone's minds, always There is no way to get an answer. According to the report, a team from the University of Aeronautics and Astronautics in Beijing, after nearly 370 days of closed life, finally simulated the life experiment on the moon, and finally knew what the final truth was. Live here for a long time.

All aspects of human beings are constantly improving, and the demand for 3D printing metal powder is also increasing.If you are engaged in the 3D printing metal powder industry, you just happen to contact us.
