While even the most detached layperson will tell you they are aware of some of the amazing and positive feats being accomplished with 3D printing — from heartwarming stories of children (and even their pets) being fitted with affordable, customized 3D printed prosthetics to information regarding global progress as 3D printing is making huge strides in manufacturing of high-quality components — most everyone is also well-acquainted with and interested in the most controversial item 3D printers can make: guns.

And gun enthusiasts certainly aren’t silencing themselves (though they can silence their guns) when it comes to putting their 3D printed designs out there to the public. What’s the point of 3D printing a cool new gun if you can’t show it off while you are spectacularly blowing away ‘stuff’ in your backyard shooting range — and especially when it comes to raising the bar with an even more powerful weapon that’s hot off the press.

Recently, there’s been excitement brewing over a new and even more powerful 3D printed lower receiver. This one has significance because, unlike some of its predecessors, it very possibly may possess not only the power, but also the resilience and durability to shoot without issue, and keepshooting without any imminent breakdown or failure looming for the user.

The PrintedFirearm team has given us all a heads up, by way of a very abbreviated clip, that indeed 3D printed gunmaking skills have been seriously elevated with the CM901, the AR-10 lower receiver, evolving past the much discussed AR-15, which while making big headlines, was problematic in its design and failure rate with many initials versions demonstrating complete breakdown.

The CM901 is being touted as a 3D printed, super powerful gun that fires the 7.62-millimeter bullet. Because this is an even heavier weapon that should suffer more substantial recoil, it’s of enormous interest that it seems to be functional right out of the gate.

The 3D printed lower receiver was produced on the XYZ da Vinci 1.0 3D Printer, retailing for $499, which is impressive to all in terms of 3D printing, but even more so to those considering getting into the business of making their own guns.

The CM901 is also versatile in its modular design, which allows it to fire off 5.56-millimeter rounds as well. The information PrintedFirearm has released so far certainly is not extensive enough for any true analysis and borders on teasing, but it is certainly enough to grab the interest of many who are going to want to test it for themselves, or at least see some more demos.
