From Ammoland:

New York is tackling the 3D-printed gun community by trying to ban the 3D printing of firearms and prevent the sharing of computer-aided design (CAD) files.

New York State Senator Brad Hoylman is sponsoring the bill. The Democrat says he wants to “attack the manufacture” of 3D Printed firearms. It would not only make it a felony to print guns but also ban the intentional sharing of files, raising First Amendment concerns. Writings like the Anarchist Cookbook and the guide to build a Luty machine gun have been determined to be protected speech. Many believe that these files are also protected speech.
