    I've read a fair few papers on the results of different gas mixes in Wire-DED. I have been using 90/10 lately but I've also used 85/15. Only mixes, no straight Argon. That's one variable I haven't...

    Using a MIG welder (Miller's RMD process right now) on a robot.

    Porosity of the weld isn't an issue so far. The only issue so far is geometry that results in a complete fusion/overlap in all...

    Laser melting is definitely a thing. There's not really a big difference in deposition rates that I can see, in my reading.

    The other issue is machine complexity and consumables, in my opinion. ...

    I've been a fan of Big Metal Additive for a while. I was put in touch with another engineer there a while back. Very cool stuff.

    I don't think it's helpful to compare the mill MMR to the deposition rate of a printer. Print speeds look like 10kg/hr and higher (only), so obviously, that's not a metric.

    But they aren't the...

    Large Metal Additive with Weld Wire

    No, I'm not talking about the dumb shapes and little animals we've probably all mud-dobbered together on the weld table when we're bored. :)

    But I've been researching more and more about Wire Arc...
