    Or perferated aluminum with high temp rubber in between most connections. Wait... not perforated aluminum. Like porous or somethings. Lots of holes drilled or forged through it for cooldown yet as strong as possible with the maximum allowed of cooldown. Maybe even thin fins sticking out in between to make more surface area so breezes cool it down. Seems easier just to go for a bulky high str material though.

    Aluminum is weaker than steel, which in turn is usually weaker than titanium alloys.

    but also incredibly cheap. And can probably be designed to have much of the force absorbed into rubber or something. There are also aluminium alloys.

    no real printting process today or anytime in the forseeable future can handle consistent shots of a firearm.they use steel and bronze powder for metal printing now,and its very weak,its mostly used for making small car parts like old stereo knobs,and is extremely fragile.titanium would require a good fusion metal,and using a fusion metal would be still weaker than steel.


    plus titanium is very expensive,for the cost of the titanium power to equal less strength than forged steel,you could still make one old fashioned quicker and cheaper on basic machining tools.

    Considering how far this technology has gone in the last tens years do you still believe what you're saying will hold true in another ten years?

    it still holds limited functionality,since it holds no ability to make stong metals needed,and if it had been deemed viable,both gun and car manufacturors would have already been dumping billions into its further developement.

    they are great for making prototype parts,or making doorknobs and fancy cabinet handles,but in terms of replacing real machinery,its not too far a cry from jb weld in terms of strength.

    It's not viable for mass produced volumes, yet, but that doesn't stop it from being very beneficial on a piece by piece basis, especially in homes and small business.

    Chrysler had one of the first 3D printers when it built it's technology center. It helped shorten the design process by two years because engineers could print out the part and use it on the prototype for fitment and access without having to order it from the machine shop, which took much longer than the 3D printer. Ancient technology at this point, though. I'm sure they've replaced the original.



    The idea of structural strength has been brought up before in this thread but I haven't seen a definitive answer on that. Do you have links?

    no definate answer on structural improvements exist because its not withing any logical grasp of knowledge to this date.the metal has to be fused,which requires a weaker metal to fuse a stronger one.in order to fuse steelpwder without a binding agent that severely reduces its strength,would require things like lasers powerfull enough to melt iron,in which case making any such printer in any forseeable future would still be more expensive than any common alternative.

    3d printers are a large step forward for many things,but they cannot and from all evidence will not replace high strength steel.

    Looks like your not gonna be able to get that file to make your own gun from this guy anymore.. [/FONT][/COLOR]
    Two things, one, the goverment is stupid, the horse has already left the barn and two, the manufacturer was NOT shut down, they have just stopped sharing the pattern. They are still free to legally manufacture from that pattern.

    I don't have a printer.

    Pro plastic-gun folks keep saying I shouldn't factor the cost of the printer in the cost of the gun, but these same people can't explain how a gun is going to jump out of the CAD file without a printer.
