This Made-At-Home 3D Printed Railgun Is An Engineering Beauty With Handsome Firepower

So, it seems ever since people have realized just how awesome railguns are, they are trying different designs to make at home. Since it requires a bit of skullduggery and recklessness to complete such a dangerous project, DIY engineer enthusiasts are at the forefront of it. This Redditor mockingly named NSA_Listbot takes his projects serious enough and he has to show the rest of the world how he made them. He recently published a long post at Imgur regarding his railgun experiment, and he tells us in detail about this magnificent 3-D portable railgun. It is probably the first one ever produced using additive manufacturing like 3-D printing.

A railgun is a device that accelerates metallic projectiles through strong electromagnetic waves. But, doing so requires powerful capacitors and understanding of the phenomenon, or it can result in a disaster. The US Navy had been developing a railgun to fire high-speed projectiles approaching 10 Mach or even more. This project from the crazy engineer is essentially the same thing, but on a much smaller scale and no explosives involved. There are an astonishing twenty pounds of capacitors used in the making of this railgun. They can create a strong electromagnetic field to fire Aluminium rounds like this:
