Radio Waves

The way these large, walk-through metal detectors work is fairly simple. One of the walls of the box sends radio waves to the other side, which are then returned. Radio waves will not pass through metal objects, so if the radio waves hit any metal on a person, the waves will be bounce back sooner than the others. The time it takes for the radio waves to travel the full length of the box is set in the machine, so that if any radio waves are bounced back sooner, the alarm in the metal detector is set off.

Adjustments

Most airport metal detectors, though, don't catch all the metal that passes through them. This is because the sensitivity of the metal detector has to be toned down slightly. Otherwise, people with metal fillings in their teeth, metal rivets in their jeans and metal zippers would all set off the alarms. However, this also brings down the effectiveness of the metal detectors. While smaller, metal items may not be detected, the settings are always set high enough that most items considered dangerous will set off the alarm.

Thank you for the clarification. Without rifling the designs I saw are a "belly gun" for use up close and personal. I wouldn't want to try to rely on it for anything over arms length ranges. Even 2" barrel concealables are rifled but we don't count on them for more than 30 feet. In the context of up close weapons that are not detectable the ceramic and plastic combat knives being currently made fir the bill and can be just as lethal.

It's all about perception.  While what you say is true, people will be more afraid of the gun than the slingshot and I would guess less likely to try to take it from you.

Airsoft is the way to go !!!

Actually I think an assassin needs a reliable weapon not some cutting edge experimental may work sometimes device....

“printing other, non-firearm models is of course still possible.”
...But it is now really really difficult, because your model of a sailboat looks just like a receiver so you can't print it.

This is even stupider than when the Dept. of Homeland Security wanted to remove the Liberator files from the internet.

I think people will just start sharing the G-code instead of the stl's which should get around this...

THEY TOOK OUR GUNS!!!

There are also plenty of people sending certain parts off to places like emachineshop and others that when assembled these ten pieces form a thing-a-ma-bob that can be fitted to another thing that uses brass containers that propel a cylindrical shaped thing well over 2000 feet per second.

Makes you wonder what kinda of *extras* micro$oft put in to help support 3d printing in the new windows???  especially now that they and some others have partnered with the NSA... Hmmmmm

As long as they use the Orange ABS it'll allow it
