X190509: 3D say a word about a true modified reuleaux-meissner tetrahedron .
..
Greetings!
It turns out that the Oloids live happily ever after their formula-formalized life, and sometimes even make their way to Kickstarter curiosities in the form of hand-finished 3D-turned geometric bodies.
Angus talks about some of the theory and about the possible applications implementations of dry formulas.
Described my translation:
I like geometrically solid objects with 'strange' properties.Have we finally found an ideal body of constant width? nine0003
Links to the theory with conclusions - in the description of the video, captions can be translated by Google.
Enjoy watching!
Regards,
Ski.

I am motivated to search and find such 3D information with relative constancy ;-) I am motivated by a phrase from a famous French film in a beautiful translation, sunk back in Soviet times:
'She was... was... She was ROUND-ANGLE!'[]

Miniature permanent magnets can be 3D printed

Scientists from the Ural Federal University and the Ural Branch of the Russian Academy of Sciences determine the optimal conditions for 3D printing of permanent magnets from hard magnetic compounds based on rare earth metals. This will allow launching small-scale production of magnets, giving them any shape during the manufacturing process, and creating complex configurations of magnets.
Such magnets are suitable for miniature electric motors and electric generators that operate pacemakers. In addition, this technology minimizes production waste and has a shorter production cycle. The description of the method and the results of the experiment are presented in the Journal of Magnetism and Magnetic Materials. nine0147
Creating complex and small magnets is a difficult scientific and technical task, but they are in demand in various specialized applications, primarily medical. One of the most promising ways to create complex-shaped parts from hard magnetic materials is 3D printing. Ural scientists managed to determine the optimal parameters for 3D printing of permanent magnets using selective laser sintering. This is an additive manufacturing method in which a magnetic material in the form of a powder is sintered in layers into a three-dimensional product of a given shape according to a pre-created 3D model. This technology allows you 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, to influence the coercive force (resistance to demagnetization). nine0003
“Producing small magnets is a difficult task. Now they are created only by cutting a large magnet into pieces, due to machining, about half of the material used turns into garbage. Also, when cutting, a large number of defects are introduced into the near-surface layer, due to which the properties of the magnet deteriorate extremely. Additive technologies make it possible to avoid this and make complex magnets, for example, with one north pole and two spatially spaced south poles, or a magnet with five south and five north poles at once. Such configurations are necessary for pacemakers, in which it is possible to assemble a rotor for an electric motor from individual magnets only under a microscope, ”explains Dmitry Neznakhin, Associate Professor of the Department of Magnetism and Magnetic Nanomaterials, Researcher at the Department of Magnetism of Solids of UrFU.

Scientists have now succeeded in making thin, about one millimeter, permanent magnets, the properties of which were similar to commercially produced magnets. The basis was a powder containing samarium, zirconium, iron and titanium. The connection has suitable characteristics for permanent magnets, however, traditional manufacturing methods deprive the connection of most of the properties. Therefore, scientists decided to check whether it would be possible to preserve the properties using the new technology.
“When creating permanent magnets based on these compounds by traditional methods, the properties of finished products are far from theoretically predicted. We have found that during sample sintering, the addition of low-melting powder from an alloy of samarium, copper, and cobalt makes it possible to preserve the magnetic characteristics of the main magnetic powder. This alloy melts at temperatures lower than the properties of the base alloy change, so the final material retains its coercive force and density,” Dmitry Neznakhin adds.

At the moment, scientists are establishing the main patterns of formation of the microstructure and magnetic properties of hard magnetic materials, determine which of the magnetic materials can be used to manufacture permanent magnets using the laser sintering method. In particular, they check how the sintering method affects the properties of another well-known base for magnets - an alloy of neodymium, iron and boron. The next stage of work will be the manufacture of bulk permanent magnets suitable for practical applications. The study was supported by the Russian Science Foundation (grant No. 21-72-10104). nine0003

Permanent magnets remain magnetic field sources for a long time. This property is used in a wide variety of industries and devices, for example, for the production of modern electric motors, household and computer equipment and other devices. Traditional methods of manufacturing permanent magnets allow you to create only large-sized products and, as a rule, with two poles - one north and one south.
Selective laser sintering is an additive manufacturing technique that uses a laser to sinter a fine powder (usually metallic) material. The laser aiming process is carried out automatically according to a pre-created 3D model, which can be created in a graphics editor. nine0003
