Well, Let's try to do something different regarding all the mig or flux core wire feeder talk that has been bantering:

Whether, 115 volt or 230 volt, I really do not care. My question is have any of used your wire feeder as an improvised handheld 3-d printer?

I will admit that I have. While not textbook, or suitable for high loading requirements, sometimes as a repairman you just run into scenarios that are too difficult, too expensive, or too time consuming to repair with the proper textbook methods especially when dealing with complex shapes.

I will admit that have used my wire as a 3-d printer to repair two mower decks on cheapo riding mowers. Proper repair procedure would have involved extensive use of fab tools that I do not own or investing immense amounts of time that I was not willing to invest on items that were otherwise basically worthless. I have used the one mower for 4 years now and the other for 3 years and my improvised repair has held fine. My portion is in better shape than than the remaining portions of the decks. I even used flux core and did not worry about slag inclusions either. (I know not good practice)

I have also used it to improvise 3-d print complex shapes that would have otherwise required milling in a milling machine to repair. Was my method the ideal repair method that I would do if selling my services (answer No). That said, was it very cheap, fast, and relatively easy compared to doing it the proper way? (answer yes and no regrets).

WOW!! It must be getting late. That went right over my head. :)

Can I assume this means you are building welds on top of each other to take up space ... as in filling a hole? If so then the answer is yes, hasn't everybody?

I dont know what you mean by 3D printing, but I have filled many a rusty hole with my mig. Only thing I can think of right now was the exhaust on my old ford escort. Pipe rusted and broke next to muffler. Car has 280,000 miles on it so I didnt feel like investing in a new muffler or tailpipe. I just brushed off the rust best I could with the pipe still on the car, and started doing spot welds until I had it fused back together. Once I had spot welds all the way around the pipe, I was able to run a bead across the top of all the spots welds. Thin rusty pipe, plenty of blow thru's, but a ton more cheaper than a new pipe and muffler. Wasnt pretty and probably not very strong, but it put a stop to the rumble of the leaky exhaust.

yup ,,, and a small piece of flattened copper pipe behind makes it easier to build up a hole / crack ....

Hole not needed.

Think of a short piece of angle iron welded to a larger plate, with one leg of the angle iron sticking up.
If that leg that sticks up were to break off, you could replace it by running a bead where the piece broke. Then keep stacking beads untill you have something close to the original part that was missing.

We call that base metal build up, not 3 D printing. Not too sure how one would use a MIG to make a 3 D model of anything, at least not very fast. I suppose if one had a computer controlled welding arm it could be used to make a build up of about anything, but it wouldn't be pretty like a molded casting.

And it would be super expensive!

I actually saw (or read?) something the other day where they were experimenting with true 3-D part fabrication with MIG, but of course there were issues. IIRC, it was an article on WW (yes they have articles) about it. I'd imagine it would require a lot of final part machining to get things in tolerance...But who knows? MIG may be crude process used to develop a whole new welding process to create parts. Sounds expensive, but what do I know?

I could visualize a process similar to MIG to create a part, which uses jetted air, or a water jet to "freeze" and true the product after the weld metal is deposited....hey wait, can I patent that idea?
