    I don't care what your opinion on guns are, if this proves successful the same tech could be used in a lot of areas that would prove extremely useful.

    I wouldn't be surprised if the major firearm manufacturers try to shut them down in one way or another.


    BTW, how will these guns deal with the heat given off every time a round is fired?

    3D printing is an interesting topic. CAD models typically rely on a smaller number of controlling data points than a tessellated model would use. It's not that they're interpolated. It's just the formula can be calculated to a high number of decimal places when they need to determine a high frequency of data points across the surface. I'm interested in how they maintain control this way to a level suitable for gun manufacturing.

    In the US, I can see this becoming a 2nd Amendment nightmare, where both Congress and SCOTUS will be tasked with having to define what exactly is a gun. The FAA will be up in arms (pun intended) on what would be allowed on the flight deck; the TSA will mistake the 3D printable ones for the real ones and miss the real ones altogether; and worst coming to worst, some kid with a plastic 3D gun, wanting to be like their hero or their big brother marine, will get arrested, or worse, shot by some other gangbanger (or worse, police) because they believe their lives were in jeopardy.

    There may be uses for this in other fields, but this could and would be a nightmare.

    The way that the article is written suggests that these are real guns. Not toys, which by law must be easily identifiable as such.

    That's quite simple. I doubt it's legal to carry a toy gun on the flight deck, and it shouldn't be a big deal prohibiting that.


    Quoted from the OP
    You could make 3d printable toy guns today. The necessary tolerance levels in manufacturing to make a toy are much more lenient than what would be required to make a weapon. I don't think this article would exist if it referred to toys. As far as I'm aware, 3d printing can use a much wider array of model types as long as they're solids. Earlier I wrote it rather poorly contrasting the use of a natively tessellated model to a patched surface model. It's not really my field, so sometimes my descriptions are off. There's nothing truly remarkable about another method of making toy guns though.

    Some thermoset polymers like Bakelite and melamine resins are much more heat-tolerant than regular thermoplastics like poly-esters.

    3D printing can also use metals.

    I thought real, working plastic guns already exist -- just not 3d printed ones.

    (or was that a Harrison ford movie I'm thinking of?)

    Glocks have a plastic frame,(?) but they still have metal parts.

    Were there not pistols made from ceramic materials that could escape detection in metal detectors.

    Interesting... I think there's a much bigger picture here.

    3d printers are probably going to have effects we can only guess at particularly with things that are proscribed by governments or have a price premium due to trademarked design etc. For example pornography used to be reasonably straightforward to control and somewhat difficult to get hold hold in some places and impossible in others due to the physical nature of the print or films. Now though it's now just a click away pretty much anywhere and it's practically impossible to control. I can see similar things happening with these printers. It's going really challenge anything that's licensed, copyrighted, a trademarked design or has an import tax etc...

    The article is written in such a way as to imply that Cody Wilson has some political agenda or other motivating this, but, it isn't clear what that agenda is. Weapons are already quite cheap and available, so, what exactly is the point?

    Gun laws are... weird. I'm no expert, and the terminology is murky to me, but here's my understanding. For purposes of law, rifles have two parts - receiver and frame. AFAIK you can purchase and sell the frame part all day long, but it's the receiver part that has restrictions and requires special approvals and all that. The deal with 3D printing is that a person can download a file off the internet to print their own receiver, attach it to a frame, and have a working weapon. A fully automatic one at that, I think, since the receiver contains the trigger and such. It's not practical for an individual to machine one out of metal themself.

    THAT is why there's a political slant to this, I think.

    You'll never see real plastic firearms. Without getting too technical, there are a few components that must be made of high strength steels. Even the Austrian-made Glock, made famous by the "plastic gun" quote from the Lethal Weapon movie isn't entirely plastic - the slide, barrel, and a few small parts are metal.

    Yes, plastic rifling wouldn't last too long, for sure.

    The guns are only good for 5 or 6 shots..

    The source seems legit, but make your own conclusions

    With 1 plastic part it broke after 6 shots. Add more plastic parts and it'll likely fail at the first one. You'd probably hurt yourself trying it.
