[solidconcepts]World’s First 3D Printed Metal Gun

post #1 of 22

Another common misconception about 3D Printing is that it’s limited to desktop printers that can only extrude plastic filament. If I had the time, I would do a complete yearlong series debunking all the myths and misconceptions surrounding 3D Printing. Instead, our engineers went ahead and built something that proves this technology beyond any doubt. So long sad disfigured Yoda heads, no more pretending like that’s going to cut it for this industry.

Laser sintering is one of the most accurate manufacturing processes available, and more than accurate enough to build the 3D Metal Printed interchangeable and interfacing parts within our 1911 series gun. The gun proves laser sintering can meet tight tolerances. 3D Metal Printing has less porosity issues than an investment cast part and better complexities than a machined part. The barrel sees chamber pressure above 20,000 psi every time the gun is fired. “We’re proving this is possible, the technology is at a place now where we can manufacture a gun with 3D Printing,” says Firestone. “As far as we know, we’re the only 3D Printing Service Provider with a Federal Firearms License (FFL). Now, if a qualifying customer needs a unique gun part in five days, we can deliver.”

These metal printers are amazing, unfortunately they won't be affordable anytime soon.

I think you will find that most 3D Printing is still pretty unaffordable, especially if you want quality parts. For toy production, a machine capable of providing quality pieces runs from at least $10k at best.

You can definitely get high-quality printers for only a couple of grand.

they use sintering to make hip replacements and stuff, but im pretty sure the parts still need finishing afterwards

hardly surprising, its just application of technology that is already available

we can already print metals and ceramics, easily make guns and engines out of titanium if wanted. pretty much anything that could come in powder form and bond/melted by the laser can be 3d printed

alternatively anything that can be extruded and bonded can also be 3d printed including stem cells

There is something almost poetic to me about the first "printed" metal gun being a 1911. I have carried one every day for a long time, and I am more than just a little fond of the platform. gunner2.gif

This will be great for people that restore vintage firearms (among the other obvious applications).

Why do they have to keep printing guns to demonstrate this stuff? All it is going to do is incite the anti-gunners. Ermagerd, what if criminals just 3d print weapons? Couldn't they just print up engine components and run it in a car for 50k miles instead of bringing firearm owners into this?

Well there are a few issues with that. First an engine is much larger and complex so it would be much more expensive. Second running thous 50k miles would take a long time to demonstrate. Third I don't think engine blue prints are even available to outsiders in the needed CAD format.
