First fully 3-D printed gun test fired

Staples has become the first major U.S. retailer to offer easy access to 3-D printers on its website. Staples is offering a printer by a company called 3D Systems known as The Cube. The 3-D printer is available for $1,299.

The Cube uses digital design files as blueprints to build physical three-dimensional objects layer-by-layer using plastic. The printer is capable of printing just about anything the user can dream up from action figures to iPhone docks and more.

The Cube can print products up to 5 1/2 inches on each dimension. Print media is available in 16 different colors and the printer ships with 25 design templates included.

Staples will also offer consumables for the 3-D printer online and in some of its stores.

Speaking of 3-D printers, a company called Defense Distributed recently tested the world's first completely 3-D printed gun. The only parts of the weapon not created using a 3-D printer are the firing pin, which is a nail, and the .380 caliber bullet. The weapon successfully completed a single test shot and misfired on an additional test shot.
 
When loaded with a more powerful 5.7 x 28 rifle cartridge the gun exploded.

It's a very well designed ammunition. I'd love to get my hands on a FiveSeven, but at $1100 they're a bit too pricey for me. The 5.7X28mm is as powerful as a .45ACP, but lighter and gives less kick back. It's a tumbler, like an M-16 round, rather than a fragmenting round. It does it's damage by tumbling through the target and spreading around the damage.

It would be a good round for a 3d printed gun, once the technology makes the plastic a bit stronger, and/or makes metallic 3d printing more available.

I agree, it's an excellent gun. I bought mine on my 21st birthday. One of the best purchases I've ever made.

Agreed about the P90 and 57 being nice weapons. Both handle extremely well and is in my opinion a special purpose 9mm replacement.

However, it does not have the stopping power of .45 ACP. Is it lethal, very much so... look at Fort Hood. But the first sworn PD (in GA) to use as their carry engaged in active fire with it, but quickly went back to his previous weapon.

IMHO... 357 Sig is the all around best pistol round. Standard issue for NJ State PD and TX DPS. Since TX has been using it, there has been only one survivor with the remaining being fatal wounds.

Maybe the 357 Sig. However, .45 ACP has withstood the test of time and has been proven time and again in actual combat.

I have both a FiveseveN and a PS90. I wouldn't trade either of them for anything. While we could get into one of those great internet fights of 9mm vs .45, I would just say that the 5.7x28mm cartridge tends to perform alot like a 9mm as far as ballistics go. The great benefit of the FiveseveN, however, is that fully loaded with 20+1 rounds the thing is 30% lighter than your typical polymer 9mm with 16+1 rounds. It is a larger firearm, however the weight is incredibly low and the recoil is light enough to make follow on shots easy. It was a great compliment to my collection of normal 9mm and .45 ACP handguns.

For those that are unfamiliar with the notation of X+1 on magazine sizes, many folks that carry, either concealed or openly, will have the firearm with a full magazine and one loaded in the chamber. This is normally done with any applicable safety on. In the unlikely event of its being needed, no time is wasted having to chamber a round.

In regards to the printed gun, no thanks. I do not plan on having any of my guns blow up in my hand. Technology is getting better, but it is not there yet.

I believe the Five seveN also has a default mag of 20 rounds, with a mildly-extended 30rd mag available, which would be more concealable than, say, the 9mm Glock stick.

But AFAIK the ammo is single-source (or near enough), and both it and the weapons themselves are crazy expensive. The civilian ammo has polymer jackets so as to not be armor piercing.

You are correct, the Five-seveN comes with three magazines, and you can choose either 10 or 20 round mags. You can also get aftermarket 30-round magazines which extend the grip by about 1.5 inches.

The ammo is basically single source -- I've only ever seen FN branded ammo. The price has always been high, but it has also been remarkably stable. When I bought the gun in 2007 it was ~$20/50. When handgun ammo spiked in price after Obama's first election, 5.7 ammo was still ~$22/50. Even now the price is still ~$22/50. So at times my Five-seveN has actually been cheaper to shoot than my 9mm.

Try reloads? I've fired thousands of rounds from these guys without a single misfire. Save a lot of money these days shooting reloads.

Didn't search for it myself, but maybe they have it. They tour a lot of gun shows too.

Strongly disagree.

Now this is coming from a Concealed Carry permit holder, and an IDPA competition shooter (still a bit noob). But there's no way I would use 5.7 as my carry. It's far more likely to just punch through someone and hit an innocent person. It has less stopping power than my .40, and far less than a .45.

The whole "tumbling" thing? Mostly not going to happen at typical self-defense shooting ranges. According to the FBI, most defensive shootings take place at ranges of 3 to 6 feet. At that range the 5.7mm isn't going to be "tumbling", it's going to probably just blow through the person and hit whatever, or whoever, is behind them.

It's not as powerful as the .45ACP. There's no reliable self-defense ammunition for it (that I would trust). A .45 will leave a very large wound cavity inside a person with very little chance of over-penetration or exiting the body with proper self-defense ammunition.

I shoot with the guys who like the FN, but it's mostly a "cheater gun" used to boost their accuracy for IDPA scores. As far as a all-around general purpose/concealed carry gun? Worthless in my opinion.
