Regarding the planes, concerns that come to mind for me is a group of terrorists boarding a plane where each of them has a (few) piece(s) of the weapon(s) that will be put together after boarding.[/quote]
More Air Marshalls and the option for flight attendants and pilots to arm themselves.
We should be doing this anyway.

Agreed

Pretty much infinite possibilities, Nokia have released tech drawings so you can make your own customized phone casing at home.
As for smuggling onto a plane, at the moment they are at least the size of a microwave so there’s little chance of that, but who knows what the future holds. [/quote]
imagine this technology in a thousand years.
you’ll be able to print your own army of terminators.

You can use high pressure plumbing parts for that bit.[/quote]
Plastic parts? You mean like schedule 80? All they are is thicker plastic.

You’d be surprised at how strong plastic can be.

haha its time to get scared when a company called ‘Skynet’ starts making them…
Finally…a playmate that won’t deflate on me.
It’s neat but we should not let it lull us into a false sense of security. Yes it can print an AR15 lower but that is a low stress part. I’ve seen one carved out of pine. It only lasted one round but if it had been a decent hard wood it would have lasted for a while. What it can’t print for now at least is ammo or a barrel that wouldn’t blow up in your face.
Also if you think that the paradigm of the gunpowder firearm firing a projectile as an effective weapon will continue indefinitely you are deluding yourself. While we can’t be certain of exactly what the capabilities of body armor or other defenses will be twenty or fifty years from now, one thing we can be certain of is they will be better than they are now. I won’t be shocked if in twenty or fifty years they have reactive armor clothing that fits and feels just like normal clothing.
That’s why we need to be vigilant about not just protecting the second amendment right to guns. We also need to be on the look out for laws that are intended to set a long standing precedent for technologies that are yet to be developed or perfected.

I agree, but I think the important thing here is you paradigm.
In a way, the only thing that matters is how to deliver controlled death from a distance.
Gunpowder propelled devices are certainly not the only answer.
This is a trip. I am constantly being amazed at the state we are in and heading with technology.

This is what I was referring to when I was talking earlier about a 3D printed (bottom receiver) of an AR-15 being used to fire over 200 rounds. We’re past the point of debate about whether or not this is a viable technology.

Hard to believe, but using SLS 3D-printing, plastic models have been built which have superior shear and tensile modulii to laminated carbon-fiber models.
Wouldn’t it be possible to use some plastic polymer that could be superior to a metal?

I think with the right person and the right amount of time and money that it can be done. Stuff like this only opens up doors to other possibilities. Why I love the science field. What these guys are doing is just that, experiments. People then can improve things or look at it in a different light. Exactly what those guys did. 3D printing experiment came out Hey, lets print a gun.
They’ll make these 3D printers hard to get or regulate them. It will take just one guy to smuggle a weapon on-board a plane which cannot be detected because it isn’t traceable.
These 3D printers will be used for human organs and other bodyparts in the future, they’re undergoing trials now.

I think you are going down the wrong path.
I dont think the way to success is making super strong plastic, though I think it will be eventually, it would probably be better to design a gun that has no parts that need to be able to withstand forces like a metal gun.
So far, they are trying to re-do guns that were always meant to be metal, they need a gun that was designed to be plastic from he start.

Hard to get or regulate? Don’t be a dick.
people said the same when colour printers came out… people will make their own money so they have to regulate them.
In 5 years this will be an industry worth 100’s of billions, u think people who will be at the forefront of this technology will let that happen?
in 5 years you’ll buy one for $300 dollars and will be printing whatever the hell you like.

I agree with you, they will design guns out of plastic end off.

Ah, thinking outside the box. That makes sense.
What changes need to be made to have a functioning firearm that’s made of plastic instead of metal?

I am no engineer.
I know though that people always try to redo old solutions without realizing that the game has changed.
You really only want to be able to move a small object, at high speed, at a specific target.
Maybe, even that is assuming to much.
The controlled explosion a firearm gets its name from might not be necessary, reducing stress on the parts.
Or putting other stresses on it that can be handled better by plastic than metal?
I dont know, they just seem to be in the “lets re-do what already is there” stage, which is not even the beginning, that is a prologue to the birth of a new technology.
