Over one year ago we covered the beginning of the MX3D project, which was a rather ambitious foray into 3D printing in metal with a industrial six-axis ABB robot arm. They had previously done a version using resin (MX3D Resin Printer), but then upgraded the system to use a heavy duty welding machine to deposit various metals.
One year later, they’ve tuned it even more. To show it off they printed a free form standing bridge that people can actually walk across.
Now obviously, that’s not a huge bridge, but think about the possibilities! It was just a prototype. They’re planning on building a full size bridge… somewhere. We’ll let you know as soon as we find out.
As shown in the featured image, a future system could use multiple sets of these robots to build even larger more complex structures. Damn.
Oh and if you’re sad because you don’t have a spare 6-axis robot to make your own version with… you can make your own metal 3D printer using that’ll cost under $1,500 — and no we didn’t miss a zero. It’s based off a very affordable Prusa i3, and a cheap MIG welder.
