Printing a real gun?

First UK conviction for making a gun with a 3D printer. The man said he didnt know it would fire but his other internet searches showeed him to be very aware.
I live in london and there is a noticeable rise in violence especially knife crime.

What is the answer. How can they prevent more guns being made with 3D printers? I have to admit i don't know anything about them.

I don't think you can stop them, how would you tell a printer to print a water pistol but not revolver?

Does everyone else understand how this printer builds a gun?

They do make guns out of plastic now, to get past metal detectors.
Would be like making anything else with a 3d printer.

Hi Templar.

Just think of a 3d printer as a normal one. The layer of ink (plastic) is printed as a thin slice of an object. The next layer of ink (plastic) is printed over the top of it. Eeventually you have lots of thin slices that are printed on top of each other. In other words a solid object the thickness of the number of layers - a bit like a sponge cake.

Each layer's image is slightly different which means the shape can grow/shrink/change shape/become hollow. The plans are just digital maps of each stacking layer to be sent to the printer.

The printers are not that expensive and they are easy to get hold of - Aldi have sold them! They take a long time printing but they are very effective.

Very hard to police the transmission of digital control plans - the enforcement agencis will have a nightmare but I am sure they will manage some form of image analysis to combat the use of them :(

Search for this on YouTube - (3D-printed house built in one week | Architecture | Dezeen) - It shows the process - albeit on a larger scale :)
