    3D Printed AR15 Lower Reciever

    So I have managed to find someone with a proper decent size 3D printer and I have the 3D cad designs for the AR15 lower end. I am very keen to see if this works and how it will work. Have you guys heard or seen and 3D printed gun stuff. Is it legal to print these out?

    As long as the end product is A cat, go nuts. Will be interesting to see how you get it to run without breaking.

    It probably won't (work well), if every single other attempt is a guide.

    Yeah I got the plans off the net and the finished products look amazing. You basically attach all the other working parts and you have a fully working AR with a plastic made lower.

    For 4 rounds.


    Not to be a downer but they're not very successful, the materials etc aren't ideal. Good luck anyway! Try find a file for one with a reinforced receiver extension socket as that's where they tend to break.

    Someone on the 4chan weapons board /k/ was doing designs for one with an integrated stock, made the whole lower assembly a lot stronger. Try and track that one down.

    Not a silly idea, ODL could do it with the sintered titanium he uses for his cans I'm sure. There was a place in Texas that used similar technology to "print" a 1911 frame. Of course, those machines aren't your home-grade 3d printer for printing ABS plastics etc, they cost hundreds of thousands of dollars


    the idea of a titanium lower isn't super necessary though.

    If memory serves, there was a P90-style lower for an AR that was 3D printed.
    Sure, ugly as f**k, but hey, it meets our stupid thumbhole laws and would be stronger than a vanilla lower.

    I used to work in 3D printing. Obviously if you use a design intended to be built out of metal, it's probably won't work out great - but if the design is appropriately modified for the printing plastic then there's absolutely no reason why it shouldn't work.
