Some have printed working guns with 3d printers and i kinda believe there will be some sort of restrictions on these devices on some point.
You mean like the restrictions on CNC & manual milling machines?
Complete guns were not printed - only the lower receiver of an AR-15 was... This happens to be the part of an AR that requires a background check to
purchase from a gun dealer. In order to make a complete gun from the printed lower receiver (If I remember correctly and we're talking about the
same guy -
), the receiver required some minor touchup after printing, in addition you have to install a lower parts
kit, buffer tube, stock, and mate it to an upper receiver that you have to purchase for about $400 or so. This project requires a bit of
mechanical/technical ability. I don't know if perception is that you press a button and a few minutes later a gun pops out ready to fire - this is
simply not the case... These parts are printed using plastic, and the pressure from firing a completely plastic gun (even a .22LR) will not be
contained by a plastic chamber or barrel. These parts need to be metal (Or at least something much stronger than plastic).
Read the link above for much more detailed info about his experience. One thing to note, he first testfired it using a .22LR conversion and it worked
good. When he went with a full power .223 round he has feeding and extraction issue. This is not quite ready for regular reliable use yet. I'm
sure his design can be tweaked to overcome the weakness of the materials, but there is no danger in 3D plastic printers being restricted because they
can print guns... Milling machines have been used for many years to make lower receivers and no restrictions yet,
Check out Weaponeer
for a ton of home made gun projects - there's a few fully functional semi-auto guns
made out of scrap metal these guys had lying around their shop...
Please stop spreading this myth that 3d printers are going to be regulated because someone printed an AR lower that doesn't even work properly with
.223 rounds. People have made more reliable guns (Lower receivers) using nothing more complicated than a drill press/drill, and for those a steady
hand even a Dremel... Research 80% lower receivers.
Sorry, I'm not really trying to be a jerk, but this is a pet peeve of mine...
With all that being said, I look forward to acquiring my own 3d printed and tinkering with some lower receivers as well. Hopefully haveblue will work
out all the bugs for us by that time.
I took a quick look at the printer in the OP and it seems ok for an entry machine if you don't mind the small print envelope and low resolution
compared to the Replicator 2
(250 micron vs 100). I think I'll save up a few more dollars and
get the Replicator 2.
