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.'"

      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 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.

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.

      I should also like to point out that 3D printing has existed for over 15 years. It just took that long to get the price and size down enough for home use. However, the seeds were there almost two decades ago. I actually held a 3D plastic model in 2000. The technology existed then.

      When it comes to making tiny transistors, there IS NO OTHER METHOD besides the conventional silicon fab.

      There were some experiments to print circuits using modified ink-jet printers (in theory, all you need is a conductor, an insulator, and an 'N-type' and a 'P-type" semiconductor). These actually worked (nobody said that they worked well, or were capable of any type of speed). Even assuming that this technology takes off and gets millions of dollars in research, there are fundamental limits in this type of technology. You will not be able to "spray" transistors at the size that we are talking.

      Now, if I wanted to prototype a million-transistor digital circuit right now without takint it to a real silicon fab, let me list the ways that this can be done today. 1) Simulate in software. 2) Put on an FPGA. All other methods (including hardware-accelerated simulations) are combinations or enhancements of the above two approaces. There is no thrid approach, even in the labs, as far as I am aware.

      Let's look at building a custom chip in a 28nm process. The mask costs are easily over one million dollars. This means that the very first chip that you get back will cost over $1,000,000. The 2nd might only be $50, but the first one is the expensive one. If you find a bug, hopefully the problem is small enough that you can re-use most of the masks. If not, expect to hand over another million for a re-spin. So, if your design is risky and you are not guaranteed that it would work, paying $250,000 for a single prototype made by some other method would be a bargain! Yet there is nobody out there offering to prototype an ASIC like this.

      The old saying is that what we have in our homes today was in the labs 20 years ago. There is nothing in the lab right now that looks promising for making your own high-density circuits right now, other than the FPGA. Low-density? Yes. Hundreds or maybe even thousands of transistors? Maybe. Millions of transistors? No way that I can forsee.
