3D Printed 1911

Interesting proof of concept, but beyond that, I would need to see some testing at high round counts.

very interesting. bUT priced way beyond my means. did they print all the parts or just the slide and frame?

All 3D printed, including the carbon fiber grips.

Just as an FYI:

"The Solid Concepts Pistol fired its 5000th round on 6 September 2014".

so its been 4+ years from the 5,000 round shot, what is it doing now? 5,000 rounds is a lot I get but I have at least that through my favorite STI.

They have been working on version 2.0

And BTW, version 1.0 was not heat treated:

“The 17-4 Stainless Steel has not been post heat treated because that would further strengthen it and we wanted to test our least strong option first,” the project engineer at Solid Concepts said.

According to the company, the over 30 components were made using a laser sintering process in which powdered metals are melted by a laser in layers using a digital plan. In this, a layer of powder is fused, then the printing machine lays down another layer and the process continues. Once complete, the excess powder is removed as are any supporting structures and the component is filed and cold hardened.

The 1911 is composed of 33 stainless steel and Inconel 625 components and even the carbon-fiber filled nylon hand grip was printed. Unlike previous plastic guns, the steel barrel of the 1911 was rifled and by directly building the barrel. Solid Concepts is keen to emphasize that, though some hand tooling was used in finishing the gun, none of it was machined. Assembly of the 1911 took less than 7 minutes.

Solid Concept says that the point of the exercise wasn't to create a cheaper pistol, but to demonstrate that 3D printing had reached the point where it could take on real world applications as well or better than conventional techniques. In this case, the printed parts were less porous than cast parts, could be made faster than conventional machining, and could be made more complex.

"The whole concept of using a laser sintering process to 3D Print a metal gun revolves around proving the reliability, accuracy and usability of metal 3D Printing as functional prototypes and end use products," says Kent Firestone, Vice President of Additive Manufacturing at Solid Concepts. "It’s a common misconception that 3D Printing isn't accurate or strong enough, and we’re working to change people’s perspective."

In the end, the printed gun barrel handled the 20,000 psi pressure of each shot with 50 rounds successfully fired, and even a few bullseyes hit at 30 yards.

"We’re proving this is possible, the technology is at a place now where we can manufacture a gun with 3D Metal Printing," says Firestone. "And we’re doing this legally. In fact, 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."

Impressive. Most impressive.

Again nothing about this since 2014? I am going to continue to play debby downer on this.

I have done some internet checking and the company that made the gun was purchased by another company in Eden Prarie, MN.

www.stratasys.com

They don't seem to have any info on their site about any weapons making of any kind. Although I am sure for money they would. I really think this was just a build to get the name out in the market.

I really like the idea of making things in a different way, evolution is really awesome in tech but this still seems like an idea that isn't profitable or viable. Remember the double 1911? Remember the lefty 1911 ( I want one of these)? This kind of stuff doesn't stick. I really think because its probably as good as it is going to get. Current mfg concepts are pretty proven and mostly fail proof.

Given the voting pattern of Minnesota, I doubt any more will be done on this.
