3D printers can even make magnets now

A cup-shaped magnet (lower right) created using the new technique Magnets are typically made via an injection molding process, which is fine if you’re manufacturing enough of them to make it worthwhile building a mold. Scientists, however, often just need a few in specific shapes for research projects or specialized sensors. Thankfully for them, a team at the Vienna University of Technology has developed a method of 3D printing magnets in any form desired. First of all, though, why would anyone want an unusually-shaped magnet? "The strength of a magnetic field is not the only factor," says project leader […]
