3D Printing With Metal: Engineers Create DIY Welding 3D Printer For Under $1,500

It’s possible to use plain old sand as the building material in a 3D printer.

Heated and fused together into shapes with cavities, it can be extremely strong and lightweight.

Someday carbon fiber printing will be possible... resulting in the strongest objects ever created by man.

"Someday carbon fiber printing will be possible... resulting in the strongest objects ever created by man."

I think they're already working on that.

I’d rather be able to print Au,in rings bars and coins.

[Vendome]

You had me at porterhouse and goat cheese.

I’m severing our relationship for the rest of it...

I don’t think the size of a breadbox has changed, so I’m pretty sure the lower receiver of an AR-15 or AK-47, and pretty much any handgun will fit inside one.

I wouldn’t want to be anywhere near the first jet turbine they test with internal 3d printed parts. It would be fun to watch though.

I’d rather be able to print Au,in rings bars and coins.

Then load the welder with a 10# roll of AU wire, and you can print all you want. You might need to adjust the current and feed rate to match the melting point, but it should work just fine. You may vaporize a fair amount, however.

I haven’t encountered a breadbox for decades, so I imagine we’ve a couple of generations who’ve never actually seen one.

3D printed meat. 3D printed meat.

ARRRRGGGGHHH!

Is the paper,
Anzalone et al.
“A Low-Cost Open-Source Metal 3-D Printer.” IEEE Access published 2 December 2013.

actually out there on the web?

If so, can any of you smarter and much better looking guys post a link to where the paper/plans are actually published?

I have exhausted my ferret like qualities and now lay spent across the keyboard. I can find lots of “closes”, but no cigar.

“Let me have a 3d-printer that can extract PU from air”

what is PU?

[Hardraade]

Plutonium.

I can dream, can’t I? And if it’s dreamable, it’s possible :).

[Hardraade]

I actually have one. Somewhere in the stacks. Wood with rolltop.

[dalereed]

I thought maybe you were using it for farts!

[null and void]

Political power grows out of the nozzle of a 3-D Printer.

[Hardraade]

Mushroom farts. Cleverly placed in democrat gun-control strongholds!

[null and void]

If obama has his way Iran will provide plenty of atmospheric Pu to extract.

[Moonman62]

This 3D metal printer prototype isn’t something you want to have in the living room.

Roxanne doesn't know FReepers.

[Titan Magroyne]

... “Call me when they design a 3D priter that can make a medium porterhouse with encrusted blue cheese topping using goat feces, red clay and pond water.”

I was with you right up until ‘goat feces,’ FRiend.

;oP

FWIW. MIG welders do NOT heat and extrude wire from the tip.

Forgive my ignorance, I'm not really a very skilled or experienced welder...but at the shop there is a welder they call a "MIG" welder and it has a spool of wire in it's innards. When I squeeze the trigger on the grip, wire comes out at the tip and is turned into molten metal along with part of my workpiece in a blazing display of electric power (especially if I'm not careful it burns holes in my workpiece or welds it to the table...).

What kind of welder izzat?
