‘World’s first 3-D printable handgun’ under fire

Why buy and deal with BGCs when you can simply make one.

I'd still rather stick with one made from metal. But an 80% AR-15 lower or a AK-47 flat are still legal to be shipped right to your door without a background check nor any type of serial number.

All homemade guns are legal if you meet the following criteria
1. They are not being made for sale or gift. Only the maker of the gun can own it.
2. You can't build anything that is illegal or regulated. No short barreled rifles or full auto.
3. You must be able to pass the background check. You don't have to take one but you must be able to pass one.

Based on that, it's much cheaper and easier to buy a gun than build it. An AR-15 lower costs $100. One that is partially finished costs $180 and you have to buy machine parts (drill bits and mills) as well as anodizing equipment to properly finish it. You usually end up with about $400 invested in that one part.

I would think that this would bring the costs related to most gun parts WAY down. I'd like a 200 dollar AR

I would love to see an actual 3D printer working and the end result. Not necessarily a handgun but just the printer itself.

Why print a gun when you can cave out the parts you need on a CNC or even manual mill and lathe?

Plastic 3d printing.........or metal with a sintered 3d printer:

CNC is the way I would go, been around a long time. Plus the cost of CNC's for home use can be quite affordable.

this. Its quite expensive right now to 3d print anything, if you dont have the materials or printer to begin with. Even a moderate one will set you back a couple of grand.

then you need a high quality 3d model, with thick enough wallsw that can handle the pressure of firing a bullet.

and its still a plastic gun. one part of it modeled wrong, and if you go to fire it, you can blow off your hand.

The risk invovled is not worth trying to do this until the technology is better


meh, by the time this happens,s we'll have phasers.

It is interesting to me that the about the only thing being talked about or hyped in regard to 3D printing, really isn't the best use of such tech.

The only bigger paradigm shift would be decentralized energy. Regulation is a major tool in the central control tool box. Imagine how radical decentralized production would be.

Do people really think 3D printing is best used for gun making?

I think a 3-D printed gun would be so cost-prohibitive it would be ridiculous to even do it. I'm wondering why 3-D printed guns are the main item being discussed in relation to this technology when there are so many more useful applications for this technology. How about prosthetics or artificial heart valves? Maybe cheaper replacement parts for household appliances or cars? What is the purpose of focusing on printed guns?

I just said the same thing. I can see a reason why the focus is on gun production.
Just look at the particular market relationship of the other uses being discussed and it becomes obvious why that is being hyped.

An elderly woman is the first person in the world to be fitted with a 3D-printed body part--a new lower jaw.

According to the BBC, the 83-year-old patient had long suffered from a badly infected lower jaw that was considered too risky to operate on by way of traditional methods. Due to the associated risks, doctors turned to 3D-printing as a viable alternative.

Contour Crafting works by setting down quick-dry cement in layers, building up the skeleton of the building. Load bearing walls are double reinforced with two rows of triangle-shaped concrete interior buttresses, while other walls use a single row. The mainly hollow walls allow for additional construction materials, such as plumbing, wiring and insulation, to be added during construction. Khoshnevis claims he could construct the entire shell of a house in 24 hours.
