3D printing has come a long way in a relatively short time. Now there is a entirely 3D printed gun dubbed the Liberator. Constructed of ABS plastic with a nail used as the firing pin this is proof of how 3D printing technology is pushing the envelope when it comes to manufacturing.
The design is open source so you can try out the Liberator yourself if you own or have access to a 3D printer click the download link to get the files. If you try it out leave a comment an tell us what you think of the design an makeup of the Liberator.
