Scientists Use 3D Printing to Print Non-magnetic Metal Powders into Magnetic Alloys
Brazil, the world's largest sugar producer, has recently switched to ethanol 3D printing metal powder price is predicted to go higher in the future.
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.

Greece will hand over Iranian oil it intercepted from a Russian-flagged tanker to the United States at the request of the U.S. Justice Department, Greek port police said recently, AFP reported. The decision angered Tehran.
In April, Greek authorities reportedly seized a Russian oil tanker, the Pegas, which was said to be heading to the Turkish port of Marmara.
Reports say the ship was docked in Calistos Bay with a crew of several people said to be Russian. The Greek coast guard said the ship had been renamed the Lana.
The report notes that the European Union imposed sanctions on Russia after the conflict broke out in February. Greek authorities seized the tanker in accordance with European Union sanctions.
According to information at the time, the tanker was carrying 115,000 tons of Iranian oil.
Iran's Ports and Maritime Organization strongly protested Greece's decision, calling it an "international bandit." "The Islamic Republic of Iran will not give up its legitimate rights and expects the Greek government to abide by its international obligations in the area of navigation and shipping," it said in a statement on its website.
Iran's Foreign Ministry, through the International Maritime Organization, called on the Greek government to release the tanker and its crew overnight, adding that "the Americans discharged their cargo," the report said.
Athens did not immediately respond to the Iranian protest and gave no further details about the oil on board or how it was handed over to the United States, the report said.
The 3D printing metal powder price is expected to increase in the next few days affected by the change in supply and demand markets.
