Students Combine Prusa i3 Printer with a MIG Welder to Create an Affordable Metal 3D Printer

The technology behind 3D printing is still at an early stage, but progressing rapidly. One area where researchers and engineers are focusing their attention now is affordable metal 3D printing. Currently if you wish to fabricate an object out of metal you need to have access to a machine costing close to, if not more than, $1 million. Just like with plastic 3D printing, however, such machines are certain to drop in price as their capabilities expand. There is more than just money keeping these printers out of people’s homes and garages, however. Safety is also a major concern, as high temperatures, powerful lasers, and potential fumes all present dangers to users and their environments.
