    Is there any regulation against a 3D printed weapon in the United States or Europe?

    Some time ago, I saw an article in Israel where they had one that was not detected by the x-ray and was fully functional!

  • Sort of.

    Fully plastic guns are banned in the United States by the Undetectable Firearms Act, because they can pass unseen through metal detectors - a huge problem. One way around this is to insert a slip of metal into the gun, thereby making it detectable by metal detectors. 3D-printed guns made of metal - were that possible - would not violate the law.

    The UFA was originally enacted in 1988, extended from 2003 to 2013, and then again until 2023. It may seem a bit unnecessary, as all-plastic guns, like the famous Liberator have structural issues that make them extremely difficult to fire when compared to a normal all-metal gun. However, then can be used.

    In Europe, gun laws vary widely by country. The European Firearms Directive is the main international agreement on gun laws, but its application varies, and it does not directly address 3D-printed guns.

    I'm not aware of a country that has an explicit law banning 3D-printed guns. The only countries that ban them either unintentionally cover them or ban guns altogether.

There's a plastic coupler that goes into the hole for the polished rods it broke then released 1 -2mm sized ball bearing all over my floor. Is it possible to just replace that coupler thingy? Or if I 3d print a replacement will it still need that coupler thingy? The first picture is the one that spilled it's guts all over my kitchen floor. The last image is an example of how it used to look like but on the left hand side. I know the image looks like it's the right but you can see

  • So, have a plastic car part I want to duplicate because the driver side part is broken (I have the passenger side part) and It isn't sold anymore. It's a small piece that would be an excellent candidate for a 3D printed replacement. I know there are companies I can send a 3D model to that will happily print it for me, but I also need to create a 3D model from the part. Is there a company or service that I could mail the part to that would return it along with a 3D model of it?

  • Assuming I've 3D design (or I've created one) which looks very similar to Lego bricks, I am allowed to 3D print them for my personal use? Do I need to obtain some permission to do so, because of some patents? Or how does it work?

  • Ironing out all my worries before buying my first 3D printer. I'm looking at getting the da Vinci miniMaker 3D printer as my first 3D printer, but it doesn't come with a heated bed. On my previous question about heating beds effect on a print, I was told that I need to use a raft to compensate for the absence of a heated bed. What I want to know is, does the software that comes with the printer allow the creation of rafts whilst/prior to printing? Or will it create rafts if need be?

  • I'm a newb and don't know much about 3D printers. In visual basic I can create vector data of 3d objects,that can be loaded into a binary or text file. Can files like this be used with a 3d printer? Example: This is a very simplified example of how the code generates 3d vector data. ju jv jw determine the size and dimensions of the object ru, rv, rw are the vector lenghts The incrementors... : next k2: next k1 Can a 3d printer read this output as is and use it to make a 3d object?

  • I use a Micro3D printer, running on OctoPi (yay!) (although this question should be relevant to any 3D printer that offers these features) and have options for raft and wave bonding. Are there best case scenarios for when it is appropriate to use (or NOT use) either? Can/should they ever both be used at the same time?
