3D printing technology has emerged that produces magnetic objects

Production of two separate components of different metalsAnd then putting them together was a hassle. These items were not very resistant and efficient. Now that has changed for the better. A new approach to existing technology allows single printing Objects with magnetic properties regression.

The innovative technology was developed by a consortium led by the Russian Scientific and Technical Institute Skoltech. It is based on a proven 3D printing method known as targeted energy deposition, in which a heat source such as a laser is used to melt metal powder as it is dispensed from a nozzle.

so far with 3D printing Things use one metal powder. Meanwhile, scientists are experimenting with the printer InssTek MX-1000 They were able to start with doses of one metal powder, aluminum bronze (copper, aluminum, and iron) and then gradually mixed it with another metal powder, marine grade stainless steel (mainly iron, chromium, and nickel), and finally only the second metal was added.

Both metals are alloys, but both are not magnetic in themselves, because they are not attracted to them magnetic metals. However, when you mix them together, an alloy is formed that exhibits soft ferromagnetic properties. This is an amazing achievement.

The researchers explained that despite the fact that the alloy itself is not permanently magnetic, it sticks strongly magnetic metals. The greatest ferromagnetic effect occurs in the center of the printed object, where aluminum bronze and marine-grade stainless steel are mixed in a 50/50 ratio and then rolled toward the ends.

Engineers from Skoltech, from the Russian state From the Maritime University of TechnologyIn Saint Petersburg, the National Research Center of the Kurchatov Institute and Belgorod State University announced that their technology could be used to build efficient electric motors for vehicles of all kinds, from cars, ships and trains to planes.

Scientists believe that thanks to them 3D printers It will also be possible to create new files Metal alloys with amazing properties. We may not be aware of the fact that we are on the verge of a revolution in 3D printing.
