In other news, they have also made 3D printed bullets.

McGovern1981, you`re either a troll or a nationalist bigot. Either way, you`re irrelevant. But I`ll answer you anyway, because I have some spare time.

Please explain to me how you would use a 3D printer, which prints objects in plastic or metal, to *print* saltpeter, charcoal and sulfur.

I don`t mean to print objects using those materials - that might be possible.

I mean to do what you have claimed is possible - to use the printer to create those materials.

Of course you could buy them and make your own explosive to use as a propellant (just like you could buy some materials and make them into a gun using conventional tools). Nobody has said you can`t, so you`re arguing against something nobody has said. Which is silly and pointless, just like talking to you.

Mr_Ike I realize that but he asked for a propellant and he got one. You could also make something far more destructive than a gun with that I`ll let you use your imagination for that one.

Mcgovern, blackpowder is pretty much useless in a semi-automatic weapon. It creates too much by-products and smoke, causing the weapon to jam very rapidly. You`ll need a smokeless powder, which is slightly more involved to make.

Besides the fact the world is already awash in modern powder and munitions but ya Queen Mummy keeps the scary stuff out of there at least that`s what they keep telling you....

@Angilion

You`ve just created a precision piece of machinery and think getting an explosive material is going to be the impassible hurdle?? LOL UK the island of denial......

75% saltpeter (5 parts)
15% charcoal (1 part)
10% sulfur (2/3 of 1 part)

So, for those who think that 3D printing can print *everything* required to fire a bullet;

How do you print the means to propel the bullet?

You can do what the person did in the video Andrew155 linked to did - print a bullet *and use explosive material manufactured in a munitions factory to propel it.* But you can`t print the required explosive material and you won`t be able to until it`s possible to print atom by atom at home, which sure as hell won`t happen by 2024.

Or you could use mechanical force to propel a bullet. Which means *you* have to supply the force for every shot. It also means that what you`ve made is essentially a bow. It would be easier and more effective to print a crossbow and quarrels.

It`s been possible for many years to make guns and bullets (but not a means to propel them) at home. All you need is some metalworking tools and materials you can buy in a hardware shop. Printing would just make precision easier.

Neither has anyone else. If you thought I did, you utterly misread my post because I explicitly stated the opposite.

In essence, a gun is a thing for throwing things very forcefully. You need a gun, a bullet *and a way to apply a very large amount of force to the bullet*.

Let`s say I make a gun and a bullet. What do I have? I have a crappy club with a small piece of material inside it. It`s not going anywhere unless I throw it. A chair leg (or any similarly shaped piece of wood) is a more dangerous weapon than a gun and a bullet.

Bullets don`t move by themselves. They need to be moved by something else. Something extremely forceful. Something explosive.

Unless, of course, you`re talking about a slingshot or a bow. They work in different ways.

Cheaper and easier to make a gun the old fashioned way.

1. Although a neat idea, as Angilion stated, it is too expensive for the average company, let alone person.

2. The fear that those whom classify themselves as anti-gun or pro-regulation comes about from private individuals manufacturing their own firearms with a 3D printer. The problem is that it is MUCH cheaper to just make one with standard machines and tools; which is 100% completely legal and requires no serial number or registration.

Yeah, I agree it`s not an issue yet. But this technology is really taking off, If this is what they have in 2014, imagine 2024.

As for the 3D printed bullets, they wouldn`t really be hard to make. I wouldn`t describe bullets as the same as explosives, either.

3D-Printed Bullets Are Terrifyingly East to Make

Still not *yet* an issue, for two reasons:

1) Printing in metal is still far too expensive for widespread use.

2) It isn`t yet possible to print explosives. Bullets are just pieces of material to be propelled by an explosion. A gun with only bullets is just an inefficient club. It won`t work as a gun because there`s nothing to propel the bullets.

The second one is the main one because it won`t be changed by a reduction in the cost of printing equipment (which is very likely to happen in the near future). It`s neither easy nor safe to manufacture explosives at home.

I`ve seen a picture of a 2-D printed gun, but it wasn`t awesome.
