The 3D Printed Working Handheld Railgun!
Playing Quake II just made me a Railgun expert!
Over the weekend a crafty maker named David Wirth uploaded pictures of his latest project to Imgur, as well as several test videos up to YouTube. Incredibly, he had created a working, handheld railgun capable of firing several different types of metal rods as ‘bullets.’ The railgun was constructed using a combination of 3D printed parts, readily available electronics and hardware. And it’s powered by a bank of six capacitors that are capable of producing over 1,800 joules of energy per shot
of The 3D printed components included parts made using a few different materials. The casing around the electronic components is made from ABS. However, as Wirth noted, “after the first test, the pressure broke a steel bolt in the injector and a piece of weak 3d-printed PLA which held the bolt in place. A new polycarbonate injector piece and nylon bolt plate were printed and the problem never happened again.”
