I seriously question the validity of these stories. I read the various reports, all of which state the company seized the printer because they felt what he was doing was illegal. None of them gives details as to how this seizure happened which I find strange since if you own a piece of equipment the manufacturer can't come and seize it at will for any reason. If it was a lease with no option to own maybe, but that is dubious as well otherwise car companies could repossess your leased car because they don't like the way you drive.
The other problem with this is it claims to be a "fully printable" gun. There are no plastics out there that can be run through a printer that will hold up to the chamber pressure or heat generated firing a round. There are some carbon-kevlar composites that might but they would not be printable.
I am going to chalk this up to internet sensationalism.
Naw . . . everything on the net is real. Someone at the Internet company confirms every story. Did you not understand that?
Seriously, it is a hard call. I do know there are certain things the guberment can confiscate if they are being used illegally. Not sure how a 3D printer fits in.
Not sure a company can just take something back. I am sure in some situations, they might be able to but then the suits arrive and who knows how a judge or jury will react. I think as soon as a jury is told that a weapon can be created from a desktop printer, you are screwed.
I also think one person's success in making a few parts to convert a gun ends up being a whopper of a story, where well stocked printed armory is just a matter of time.
But i also think being able to create useful products like vintage motorcycle trim parts would be cool.
Lots of far worse things to worry about I should think.
As for materials and their strength and ability to handle pressure, there are many such material out there. And if ultra-strong materials are demanded by the growing 3D printer users base, they will most certainly arrive.
They are creating new chemical compounds with a 3D printer for example. Automated (I do not know how automated this process is) custom compounding can lead to some issues for society.
I am not saying the sky is about to fall, but the rapid deployment of some pretty amazing technology is happening at a rapid pace. I think we have the equipment now all we need are the materials and they will arrive.
At Palm, we made case parts with a device like a 3D printer. Twin laser beams scanned a vat of polymers and where the laser beams crossed, the different frequency of the combined light hardened the plastic. We created all kinds of shapes including round areas that looked like tubes.
So barrels could be easily fashioned.
