I'm working on a metal 3D printer which can print with welding wire instead of plastic filament which melts by a high current flowing through it.
At the moment, the printer is operable but I'm still looking for the right slicer settings. The machine is compatible with all slicer software for normal fdm printers and at all very similar.
It would be nice if someone is interested in building it and testing it out. It would also be nice to hear your opinion on it or maybe any suggestions.
Here is the project on Hackaday.io

Looks like a guided MIG welder.

A MIG welder's best friend is a grinder?

Hi cozmicray,
yes I think so

The printer is actually an evolved spot welder, built from an old microwave oven transformer with a 3D printer around it.

Hi,

this really caught my interests. I am about to get investment to my FDM 3D printer startup and in long term - this looks interesting.

1) What are the estimated costs of printing (not only for the material but also with printer investment to paid out,with labour costs) from the perspective of consumer?
2) After printing what is necessary to do (like brushing, removing supports and so on)? What would be typical application of the prints?
