RE: Here is my rotten Lilly, who owns a piece of my heart!
sir smithlabs..how can there be stainless steel and high carbon steel in liquid form? you telling me they have that kind of technology? I mean without it being molten.
A MIG melts the metal with the arc, whatever that metal is. The metal is fed as wire, into the MIG, when the wire touches, it arcs the tip off and deposit what it burned; to the new object.
I think I could do this myself with my 3-D printer tied to my MIG welder.
:Dno way sir smithlabs, no way. if you do you have to do posts about it because people have no idea that this can be done with metals.
You should see a flame spray booth! It is basically a spray paint can that sprays molten metal like paint! The use it to add metal back to older parts so they can be reground back to original size.
Life is filled with wonders, and it is never boring!
:Dwell sir smithlabs all of this is freaky, I mean I thought not long ago I read that they couldn't do metal with 3D printers because metal wasn't liquid! now they are doing it!
With sufficient energy input, metal is liquid; or with more energy, it becomes a gas. All that is required is a significant, controlled, input of said energy. For a small deposit of metal, a small energy surge will be enough. I would us a large capacitance storage bank of capacitors. A pulsed RF starter (kind of an arc igniter) would give precision control.
I add energy in an electric furnace, and pour metal into molds. Very few limits on what can be made that way.
:)ok well sir smithlabs I would like to see these metal printers in action, are there any videos of such machines?
Many things wrong with this setup. No safety gear, he is spraying onto a machine tool, which will destroy that tool. He is hand holding the part. BUT this shows the basic function, and you see this is a LOW tech shop! He is building up the part he is holding, so he can rework it.
Enjoy
:Dok so that video shows the basic process, that's the way it would look in the metal 3D printers?
