    There's a good intro-discussion article here about one of the really interesting points of an wire-fed additive process:
    Wire-arc additive manufacturing can be used to build very large parts to...

    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.

    There are case studies about being able to print train parts in...

    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...

    That is super interesting. Sounds like a pretty cool student gig. Bet you got to learn a good bit seeing one of the extremes of power engineering in action.

    I think the addition of alloying...

    Yea, imo, the powder stuff is pretty settled and being used anywhere it makes sense. It's very expensive for metals and the machines even more so. We have some products we've designed for use in...

    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...

    I think nTopology has probably the most clever and ingenuitive approach to creating, defining, and analyzing these structures. I have not put it into practice but they certainly stand out from the...

    More has to do with the fact that it's impossible to be shot when there isn't a gun.

    I only mention it because just like "gun murder rates" I don't care what tool was used to harm. I'd rather...

    People with a gun are more likely to shoot a gun than people without a gun.

    Mine had right hand.

    You shouldn't need much "oomf" to break it free. They almost assuredly use Rocksett, which doesn't require much torque to break. Comparable to blue loctite, actually weaker,...

    If it's just an edge break to deburr, like I mentioned, no big deal. If it's to put a more significant chamfer on it, for aesthetic purpose, the customer (IME) has nitpicky requirements for "looks"...

    Never underestimate how picky a customer can be when they introduce the word "aesthetic".

    I've learned the hard way that the word "aesthetic" raises all sorts of flags unless my next question is...

    First part that might be making a difference - I'm assuming the chamfer need to look even (equal leg length) and equal angle, and consistent all around.

    With that said, keeping a standard chamfer...
