Polymagnets – 3D Printable Magnets
3D printing technology is all the rage these days; everyone is talking about it in tech circles, and the possibilities of what can be done with it are almost limitless. Generally, what makes headlines across social media platforms are the big, flashy possibilities – things like being able to print out large, complex objects such as cars, or even bigger applications, such as entire houses or buildings.
However, 3D printing offers a number of possibilities for the creation of smaller, less conspicuous objects too – although the fact that they are smaller and perhaps less spectacular than houses or cars has no bearing on how fascinating and, of course, useful and broad-ranging the applications for these objects could be. Specifically, in this article, we’re talking about magnets. Yes, that’s right: 3D printed magnets.
First, a bit of basic information about standard magnets. Generally, a magnet will have a north field and a south field, each on opposite ends of the magnet. Like fields repel one another, while opposite fields attract one another. This has been how magnets have been produced for a long time, but now, with the advent of 3D printing technology, polymagnets that have multiple north and south fields on the same side can be created.
What creating magnets with north and south poles on the same face does is to strengthen the closed circuits – the circuits that normally run in a circular pattern on standard magnets from their north and south poles – in a much more compact fashion, generating more intense power closer to the surface of the magnet while also reducing the field of interference. This means that in terms of practical applications, magnets can be tailor-made with just the right amount of force at the surface level to grip the object they’re designed to be attached to with minimal loss of force and maximum strength, all without creating a sizable field of possible interference.
Furthermore, these magnets can be manipulated in the manufacturing process to give them a number of interesting and unusual characteristics. For example, pairs of magnets can be produced that have simultaneous forces of attraction and repulsion on the same axis. This is great for a device that needs both a “springing” and “locking” function.
Basically, this technology is brand new – so new in fact, that all the possible applications of it have not yet even been imagined, and it certainly is potentially revolutionary in terms of how wide-ranging future applications could be. Keep your eyes open for the many amazing advances this technology will no doubt produce.
