Here is something to worry about - Page 1

"When these 3-D firearms are manufactured, some of the weapons can defeat normal detection such as metal detectors, wands, and it could present a problem to public safety in a venue such as an airport, an arena, a courthouse," says ATF assistant director Richard Marianos.​

The Undetectable Firearms Act, due to expire at midnight on December 9, was passed in 1988 and renewed twice, in 1998 and 2003. The law demanded all gun manufacturers producing firearms with plastic to ensure that at least a part of the weapon contains enough steel to trigger a metal detector.

But the boom in 3D printing technology has become a game changer that could potentially revolutionize not only the firearms market - 3D-printing is starting to flourish in many high-tech fields, such as medicine, space exploration andmilitary.

 

Yeah.  Anyone understand how they can get those 3D model
weapons to shoot without any metal bits in them ?  Don't the
people who take them through Customs still have to have 
detectable metal parts n ammo hidden somewhere on their
persons ?

This is not new.
The only thing would be the ammo, but the smallest part (primer) might not set off an alarm.
Ammo could be hidden in another object made of metal visibly passed through at face value.
Very limited and about as dangerous as a box cutter...
 

Don't you think the 3-D printer opens up a new realm of possibilities for exploitation in unintended ways? Not just this  immediate stop gap realization by our leaders.

Babysitting is only going to work for so long.

And then what? This invention is unbelievable. What it can do. For incredibly small amounts of money ... when you talk precision... OMG.

Look ahead. More people, more control, more people, more control, relying less and less on personal constitution, self-discipline, ethics, and morality.  No room for freedom there.

@ unintended use; That's an easy fix....ban all inventions and don't allow 'consumers' to buy 3D printers. And by all means, follow your leader. Lmao

Real constructive Joanro.
 

I think it was relavent carlin......all things considered.
