Funny I was just thinking the other day. There is local gun buy-back going on this weekend and they are giving $200 per "assault rifle". So I wonder what would happen if you printed off 100 AR lowers and took them to a buy-back
Those printers won't work for printing guns. They could make something that LOOKS like a gun, but it won't work. It can't be done on the budget printers.not true.
there are many printers available for <$1,000.
if you want to build it yourself, they can be had for ~$400.

To use the better materials and tolerances you need the $15,000 printers.

Are printed springs for a 30 rd magazine, or a 20, feasible in your opinion? It sounds like it.
Check out FormLabs Form 1 stereolithography printer. I've been touting them lately, since I think they are going to deliver a great product once it hits market, and they fit nicely between the Repraps and 15K$ industrial machines with a ~3K$ printer. Volume is 6x6x5" I think, and uses a liquid polymer solidified with a laser to build parts. Accuracy is around 10micron, I believe (I may be missing a decimal ) and strength/finish is on par with injection molded acrylic plastic (material strength varies with polymer, of course). The goo is a little over 100$ for 1L, which is pricey compared to ABS, but not compared to machining the thingThose printers won't work for printing guns.

Don't you bet on it. Aside from the need to reinforce a couple things (barrel, chamber tubes and firing pin) a low-grade revolver capable of firing a couple low-power shots is likely possible at present. Granted, it'd go out of time or wear out the sear in a couple shots, but it would be about as durable as the el cheapo Spanish/Belgian knockoffs of American revolvers at the turn of the century. But yeah, a guy simply printing a S&W 27 from CAD models off the internet would only accomplish the murder of his hands and eyesMost recent episode of CSI:NY they showed some giuy printing a revolver. Fully functional, moving parts and all, no assembly required. Part of me laughed at it, but the general public won't understand that current state of the art is not even withing rock throwing distance of that capability.
so youll likely end up with a 30 round mag that will be the length of a 60 round mag.....and i cant imagine it being too terribly reliable.
how long until the government shoves their face into 3d printing ?

2: The printed body and follower do not have sufficient lubricity against each other to move freely. The inside of a polymer magazine is glass smooth and the followers are usually IM delrin plastic. We need either a self-lubricating printing fluid or these magazines will require some post-printing finishing.
