There are plenty of kit 3D printers out there that can make things out of everything from chocolate and sugar to plastic…. and now metal. A team at Michigan Tech managed to turn a traditional delta style printer on it’s head and combine it with a MIG Welder to create a device that can be built for less than $2000. For the hobbyist who is looking for a great way to fabricate a whole new level of creations the plans and designs are all open source. Check out the details of the device and a summary of the paper at Appropedia.
