Wonder how quickly this will progress…

I’m kind of skeptical of these efforts. Those guys at Michigan State did something very similar, but at least were able to print out a very rough “gear-like” object. Metals create such a challenge due to the fact that you are literally melting it, as opposed to just reaching a recrystallization temperature. That added to the fact that metal is very thermally conductive, leads to a very difficult situation. Especially due to the fact that most of these designs are done in ambient, so the temperature gradient across the part is huge, causing massive warping.

But I truly hope I’m proven wrong, as an affordable metal printer would be a game changer in the commercial world.

I am surprised that the claim “Has Developed”. I only see some noncontinuous 2D lines. At best you can call is “Is developing”.
This is not the first person who attached a welder to a 3D platform.
