All i know about 3D printing is that its not as simple as going file, then down to print, then hit ok.

Im sure this is what law makers think.

You get a "C-" on your answer/question/knowledge.

You're talking about CNC machines.  Before we were talking about 3D printers.  Is it your understanding the two are interchangeable?

In order for a CNC machine to properly operate, it must not only follow the design of the intended item to be formed, but it must also monitor the positioning and relative distance from the origin, as well as ensure the desired actions are within the parameters of what the machine is capable of.

So, any input data must be reviewed and possibly updated to be within the capabilities of any given CNC setup.

I understand the difference between a CNC milling machine and a 3D printer. I realized I may not have used correct technical jargon in the begging but my point did not rest on the difference between one type of computer automated manufacturing device and another.

Agreed.

I really wouldn't even trust most 3D printing machines to be able to build most of the key components to a firearm. I am sure the trigger would function fine but wouldn't trust a barrel or mechanism.

And, your point?   

You guys accumulated a lot of knowledge for younger peeps to catch up to    It's like  a race where you guys got 2 miles head start.

I likely didn't like you guys who brought the grade curve up.
I failed Pascal. First language I learned was BASIC on a Timex Sinclair with a membrane keyboard. Was on sale at Longs for $99. Typing on a membrane sucked.

Even the homie in New Jack City know to program Pascal. . .

You not my frwen.

in New Jack he asked Pookie if he could code Pascal. Get it right G Money.

I was at a tech convention in TX 3 yrs ago and there was a booth there that was printing with sintered titanium particles suspended in a liquid medium and then post curing it in an oven to create fully functional titanium prototype pieces. resolution was way more accurate than 3d printing plastics, only post finish was tossing it in a tumbler. Its not yet at a consumer price point, but it will be soon enough. Cat's out of the bag after that.

As the 2nd video I posted shows, that cat is already out of the bag.

With a block of METAL (or any viable material) and a CNC milling machine (with proper design and calibration data), you can produce an AR lower receiver in less than 3 hours.  The milling machine is only $250.

Much more cost-effective, I think.  Titanium isn't cheap.

Dammit. . . mah bad Nino.  How about Kareem, the educated brotha from the bank?

I would worry about how strong the bond was because unless you are at titanium forging temperatures I would think it would still rely on some sort of adhesive.

Nope.  Bonding is at the molecular level.  Just like melting but without liquefaction.

sounds like SLA printing

They were not revealing all the proprietary technology behind the sinitering process, the  temperatures to cure werent very high, there may be polymers involved. The parts have to be printed slightly larger because they shrink during curing.  The end product was legit, its not a gimmick, they were making one-off custom rigging pieces for high end Americas Cup sailboats among other things. For all purposes it was metal.

Thats just a lower, which really isnt even a moving part put under stress in a firearm, you could almost carve one out of wood and it would function for its purpose. Once you can print ALL parts of a fire arm and cases the only thing they can try and restrict is smokeless powder and primers.

The issue is whether the AR lower receiver can be created from a "0%" blank by someone without special skills and with inexpensive & readily available machines.  If one can acquire the needed equipment and materials legally, then banning 80% lowers is a futile and ridiculous law.

All the moving parts and parts needing to withstand stress are presently not controlled as firearms.  Those components would still be available without permits or registrations unless someone decides that's a "loophole", too.

That's when lawmakers begin their trek down the rabbit hole of Socialist countries which confiscate all guns and all gun-making parts or tools in an effort to deprive the public of all guns.  Unless they actually ban all semi-autos, there's no need for them to ban all gun parts.  Why build when you can find a factory-built firearm?

read the "ghost gun" bill, it actually does ban all gun parts

and there are multiple bills held over from last session, and one new one this year that contains a grandfather clause, that attempt to ban semi-autos

And then like every other Prohibition that has ever been tried it instantly creates a black market where NOTHING is regulated and criminals war over the massive profits to be had. In the age where they are legalizing drugs because they know they cant stop it I find it hilarious they think outlawing guns will stop some industrious folks from turning that into a very profitable business.

The ban is on purchasing or producing parts for the purpose of assembling a firearm but it specifies those parts as parts which assemble to form a receiver or a combination of parts that if assembled would form a firearm.

So having a trigger by itself would not be a violation. Having all the parts to make a lower could be a violation though and having a part meant to be finished into a receiver would be a violation.

so you're saying if I have ALL the parts it's a violation, but if I only have one part it's not?
"Any combination of parts from which a firearm having no serial number may be readily assembled; provided that the parts do not have the capacity to function as a firearm unless assembled."
and are you telling me all your fellow officers are going to interpret it that way?
