Most of us have played magnets when we were young. The general magnets have positive and negative poles, which is very amazing. The use of magnets in our daily lives is also extensive, and it is so widely that you almost ignore it. However, the groundbreaking work of Correlated Magnetics Research (CMR), which has been working on magnetic mechanics, will prove to you that magnetics actually have many amazing features that are unknown.
Recently, the startup has developed a revolutionary new magnet, Polymagnets. This magnet is unique in that it has a special magnetic field for 3D printing . The same surface, resulting in many novel and useful features, is enough to revolutionize our current product design.
It is understood that CMR has been established for several years, but their technology is too new, so until now, they are still discovering new applications of this technology. The research director of the technology is Larry Fullerton, the company's co-founder and chief scientist. He brought his childhood obsession with magnets into the lab and found a way to organize the magnet structure to create more Complex magnetic fields - this is the technical basis for the company's 3D printed magnets.
This is a very unique technology, and they have obtained more than 100 patents to date, the most important of which is the magnetic shear transfer device (2014). This technology was developed a few years ago as their first magnetized 3D printer, the Mini MagPrinter, which prints magnetic fields onto magnets. Basically, this is a very rare 3D printing technique that involves the nature of the magnet itself.
According to Jason Morgan, head of the development of Polymagnets, they have mastered the magnets to get the functionality beyond ordinary magnets. The biggest feature of Polymagnets is that the magnetic field is condensed on one side of the magnet, not the two sides we usually see. “The reality is that we have moved the north and south poles of the magnet to the same surface. The advantage is that you will have a very compact magnetic field and the magnetic force will gather near the magnet, unlike a traditional magnet. Large magnetic fields waste energy,†Morgan explained.
The two magnets of CMR's 3D printing have a strong repulsive force between them, so they can't be touched at all, but the user only needs a slight spin, and they suddenly sucked together and it is very amazing.
Of course this is just the simplest application, they have more complicated patterns. Polymagnets are currently proven to be used in the manufacture of magnetic springs, magnetic locks and automatic connectors. Because its magnetic field is optimized, Polymagnets' magnetic force is five times stronger than conventional magnets, and because its magnetic field is small and compact, it has less impact on sensitive electronic products. Last year, CMR also introduced an intelligent Polymagnet kit for easy and accurate fixing of tablets, keyboards and mobile phone accessories.
More importantly, they can be customized with a dedicated 3D printer. “CMR invented a new, software-driven magnetizer that opened up a whole new magnetic system. This 3D printer is not simply configured with the north and south poles, but instead is based on a custom designed structure of the software. Printed into the magnet," the company explained. Because they cover the complex north and south poles on the same surface, these Polymagnets are very different from the magnets we usually know.
In this case, the Mini MagPrinter simply "prints" the array of magnetic regions onto each piece of magnetic material. “Each Polymagnet is a smaller magnet system with north and south poles, all implanted by MagPrinter. Traditional magnets can be placed into MagPrinter and become Polymagnet. Users only need to select a mode in the Polymagnet directory, then The 3D printer reprograms it to have some different features," they said. It can be applied to the strongest neodymium magnets, as well as to softer materials, ferrites and other special materials such as samarium cobalt.
If one thing is certain, it is their magnet 3D printer Mini MagPrinter's appeal to the maker and maker space is unquestionable. Unfortunately, even this mini version of MagPrinter is still very expensive and sells for as much as $45,000. This means that CMR's technology will be largely limited to research institutes and universities, but the well-funded maker space can also be tried. Fortunately, the price of Polymagnets is very cheap, and the price of each 3D printed custom magnet is only a few dollars, and there are almost 200 different designs available in the company's online store.
