RE: Here is my rotten Lilly, who owns a piece of my heart!
sir smithlabs..sounds like a good strategy. hey I saw a clip tonight by HP and they have these new 3D printers that print out metal parts, I thought that was very interesting.
That is a goal, using MIG welding. Should work fine, but the arc noise will cause the CNC movement unit big problems. Interesting engineering problem....
:)oh so you already know what hp is doing in the area of 3D printers smithlabs? I don't know what the problems are but I'm sure if you're an engineer it would be fascinating.
Not just HP, there are a dozen or so working on this problem. HP is a good company, I am not surprised they are ahead.
The problem is, every time they move, they strike a small arc. This arc, by it's very nature; generates massive EMI (electro-magnetic Interference) and the system must filter this EMI out so it does not affect the motion control work.
I would split the two. Move...arc...move...arc... A little slower, but it would run forever.
:)oh ok well I'm sure that one of the main goals is about speed so they can have a high volume of parts being made right?
Yes, it is a trade off. Also, different metals will need different settings. Soft steel will run faster than high carbon steel will. Stainless Steel, will be slower yet, so the production speed will vary significantly.
Right now 3-D printing of plastic, dipped in ceramic coatings, and poured with required metal, is the quickest way to get metal part made in bulk.
:)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.
