UK Police Seize 3D-Printed 'Gun Parts,' Which Are Actually Spare Printer Parts

nk497 writes "Police in Manchester have arrested a man and seized what they claim are 3D printed components to a gun. They made the arrest after a 'significant' discovery of a 3D printed 'trigger' and 'magazine,' saying they were now testing the parts to see if they were viable. 3D printing experts, however, said the objects were actually spare parts for the printer. 'As soon as I saw the picture... I instantly thought, "I know that part,"' said Scott Crawford, head of 3D printing firm Revolv3D. 'They designed an upgrade for the printer soon after it was launched, and most people will have downloaded and upgraded this part within their printer. It basically pulls the plastic filament, and it used to jam an awful lot. The new system that they've put out, which includes that little lever that they're claiming is the trigger, is most definitely the same part.'"

FTFA: "The man was also arrested on suspicion of making gunpowder"

He was probably making coffee...

It's also worth pointing out that there is absolutely nothing illegal about triggers or magazines in the UK. My father owns several deactivated guns, all of which have real metal gun triggers (not simply trigger shaped bits of plastic) and at least one has a magazine. These are legal and have been certified as properly deactivated yet that process does not involve doing anything to damage/limit those components. (Chambers on a revolver are blocked as part of the process however.)

So if it's not illegal to own real triggers and magazines, why is it illegal to make plastic things that look like them? Actual construction of a firearm out of plastic gun shaped bits should be illegal in a country where firearms are illegal of course. This is similar to black powder guns, or guns of obsolete calibre (for which ammo is not readily available), these do not need to be deactivated however if you make or acquire ammo for them from somewhere then you're in trouble.

I love that the Greater Manchester Police site has suffered the curse of slashdot. :)

If this is what the Greater Manchester Police are like, I'd hate to meet up with the Lesser ones.

Printing an iPod??? Not a chance. Printing an iPod case? Sure.

Sorry, you cannot print electronics. Well, you *CAN* (some have experimented with this), but your iPod would have the size and consistency of a phone book. Even a simple processor these days consists of tens of millions of transistors. Same for memory.

I can envision two scenarios for printing electronics:

1) Print just the board yourself. This is certainly feasible, eventually. However, assembly of something the level of a iPod requres soldering which simply cannot be done at home. Try soldering a BGA with 1,000 pins. This CAN be done is a toaster oven (but not by beginners), but requires a lot of knowledge to get it to work. Add in memory, caps, resistors, etc., and the odds of getting something out without any defects seems unlikely.

2) Print the entire circuit yourself. It is possible to print transistors, but not to the scale needed. I would guestimate that thousands of transistors on a sheet of paper would be possible, but that is still a far way off from printing millions. Modern transistors can most closely be compared in size to a red blood cell. That sort of scale is difiicult to achieve with billions of dollars of equipment.

Printing of electronics will be awesome when it comes, but it will have limits. Expect some fantastic hobbyist inventions, but it will not be able to even come close to commercial products.

I was about to make a comment about how modern music is garbage, and that people only download the stuff made a long time ago and probably that they already owned at some point, but then I realized that there are a bunch of damn kids on my lawn again.

Well, I do have a master's degree in electrical engineering, and I design silicon for a living. I think that makes me at least a little qualified to answer. I am also capable of making a point without having to resort to personal attacks and insults. That is the sort of thing that you do when you do not know enough to actually use facts.

The problem with electronics is one of scale. To get millions of transistors, you need TINY transistors. Tiny transistors = machines with extreme precision, and an incredibly clean environment. Current technology has 28 nm process as the mainstream, with 22 nm being more cutting edge, and right now, anything smaller is "bleeding edge" with yield problems.

So, given this, I would consider 250 nm to be a nice goal to be able to do anything "real." 250 nm is 1997 technology, and ten times larger than current processes (along one axis, 100 times bigger for 2D items). This is about the same size as some larger viruses!!! Can you imagine a home device capable of the precision of the size of a virus? How much would that cost?

Now, home electronics DOES have a lot of DIY-type stuff. Things like the Arduino come to mind. How about an FPGA (since you are an expert, I am sure that you already know what an FPGA is)? The humble FPGA is one of the greatest things for a DIY-electronics enthusiast. If there is to be a real home-electronics revolution, it will likely come from making your own boards, maybe with a few hundred transistors for analog and interface stuff, along with an FPGA to do all of the heavy lifting. Still, soldering a large FPGA is not for the timid.
