If you have been listening to the news lately, you have definitely heard that New York Senator Chuck Schumer proposed a bill entitled the “Undetectable Firearms Modernization Act that would ban the 3D printing of guns.” It seems that there are dangerous folks building guns with 3D printers.
3D printers are able to “print” 3-dimensional objects by weaving together plastic polymers into any shape the maker desires.
The guns are made of plastic and can fool metal detectors. “A terrorist can easily open a gun factory in his or her garage,” Senator Schumer said. “And the only thing they need is a computer and a little over a thousand dollars. No background check and you don’t even need to leave your house to make hundreds of these guns.”
People in the gun industry say it will be some time before a working gun could be made as a practical matter, but that it is something the ATF will certainly be monitoring.
We hope Schumer is successful. 3D printers have a huge potential. They don’t need a bad rap.

Only fools continue to try to control weapons. They are easy to make in all forms and will be made by people that want them. Let’s focus on behavior and prosperity. When people are safe, warm and feel self worth they are helpers not “hurters”.
Schumer is a nut case.
One answer to the problem would be to require that the plastic material used in all 3-D printers contain a metallic substance that would enable the guns, or anything else for that matter, to be seen in x-rays and metal detectors.
