While the world is fascinated with the merits of 3D printing which gave way to the concept of the 3D printed gun and the 3D printed bullet, global crime and violence experts are in a frenzy how to spot the potential terrorism menace that could go with it.

Though handheld and body scanners abound in almost every nook around the world, these only detect metal components. Versus the 3D printed gun, these scanners prove worthless because the device is entirely made of plastic except for a small firing pin and ammunition. But since technology continually evolves, it was just a matter of time before the 3D printed gun gets equipped with a 3D printed bullet.

Taofledermaus, a YouTube user, has created what could the world's first 3D printed shotgun slug.

Created with the help of a 3D printer, the 3D printed shotgun slug still needed a primer and a metal slug at the end in order to help keep the direction straight.

Using three different 3D printed bullets, Taofledermaus tested their invention with a Mossberg 590 shotgun. Despite faulty designs, one bullet managed to reach its destination, even if its interior wasn't solid enough. The first two fired bullets looked like normal shells, both of different sizes. The first slug managed to go through a dart board, and then toppled off a jug behind it. The second managed to go right through a 2-inch thick board sideways.

Experts foresee inventors and even the plain folks will surely get more creative in their 3D printing design objects.

"I'm not saying it's going to happen tomorrow, or weeks or years from now, but there will be an increased capability for a small organization to create sophisticated biological or chemical weaponry," Connor M. McNulty, who co-authored a paper on 3D printing security concerns, earlier said.

Just last week, an experiment to smuggle the 3D printed gun into a train in Europe proved successful after so-called sophisticated machines failed to detect the device.

A May 21 intelligence bulletin released by the U.S. Department of Homeland Security did confirm the potential terrorism scare the 3D printed gun and printed bullet can give.

"Significant advances in three-dimensional (3D) printing capabilities, availability of free digital 3D printer files for firearms components, and difficulty regulating file sharing may present public safety risks from unqualified gun seekers who obtain or manufacture 3D printed guns," the bulletin stated.

What's even more scary is that "limiting access may be impossible."

"This is a serious threat," an unidentified law enforcement source told FoxNews. "These could defeat magnetometers. The only security procedure to catch [the 3D firearms] is a pat down. Is America ready for pat-downs at every event?"
