First 3D printed metal gun

Looks like it shoots well too. A 1911 of course. I want one.

Think of the possibilities of parts you could make for the MB.

Repressive governments everywhere lost a bit...good!

Amazing to me that they even printed the barrel with the rifling built in, and it only needed minimal polishing, no machine work at all.

I wonder how hard laser-sintered rifling will be -- see how the gun works after 5000 rounds, not 50...

Glenn Beck had the guy on his TV spot maybe 6 months ago if not longer.
You should broaden your self educational horizons.

I tell you, they are. The science is here and now......even make food with the printers.

I wonder if they could print a printing press. I bet they could.

What Beck had on was crude stages.....but highly effective and workable.....the biggie is this science has grown way beyond what Beck showed and is blooming like you couldn't imagine.

Its a manufacturing device.......yes they can....one part at a time.

Run 3d printing on goog and see what comes up.

fascinating technology. Im familar with the nylon plastic 3d printing, but that setup lays down a layer of glue, then nylon, then glue, ect.

How does the pure metal setup work? how is the material bonded?

The death of toolmaking as we know it...How sad.

A powerful laser melts/fuses a metal power into a cohesive object.

I don't think so just yet. This technology necessitates possession of a half a million dollar machine probably.

The plastic rapid prototyping stuff has been around for a long time, and people still bake stuff out of clay, sculpy, and whip up cardboard models because it costs a fraction of a percent still.

i think there will always be a place for traditional toolmaking probably, and machinists definitely, because while im willing to pay a machinist a few hundred bucks to whip me up a custom widget, I don't want to pay a company that can afford one of these machines, 15k for the same widget.

There is an intellectual part of the tooling business that cannot get lost (if we want this tooling to actually work. JPL - you know this.

(especially if you look at the age/skill of the CAD operators these days

interesting, amazing technology!
