Technology

Depends on the type of 3D printer.

Fused Deposition Modeling, the standard "filament" 3D printing everyone thinks about when hearing the word 3D printing prints with plastics - of some sort. All of them,to a certain degree.

There are incredibly sturdy options nowadays, which include carbon fibers, but in the end the adhesions between layers will always be an issue. There are also options to print a cast for a mold and some funny techniques where you print a model with a specialised filament that is half plastic,half metal powder and send it to a company which "burn off" the plastic part, replace it with metal and send you back an (almost as sturdy as a cast) part that is fully metal.

Resin based printing is also a thing but not nearly as sturdy as FDM.

Last but not least there is metal powder based SLS(Selective Laser Sintering), but that does not produce those sturdy parts everyone thinks of, is extremely sensitive/requires a lot of knowledge and lastly money - these printers start around 20k for the better models.

In terms of additive manufacturing people are able to print non load bearing gun parts. Maybe even sturdier than before. And easier. (A 400$ printer nowadays does what a 1300$ printer did a year ago and a 15000$ printer did 15 years ago. But for everything load/pressure/shock bearing, like a barrel, spring assembly,firing pin,etc. will still need to be from pure metal. So people would still need to improvise these,most important, parts.

BUT: There are also self-built CNC machines. MPCNC, etc. are a thing, and more advanced projects for around 2500-3000$ omwards can easily achieve a level of precision on steel that is more than sufficient for an all metal ghost gun and close to what industrial guns makers in WW1, maybe even WW2, achieved.

It's currently really the golden age of home manufacturing.

Metals, catbon fiber but I heard thise nozzles wear out fast. One printer i saw used lasers to weld metal powder into shapes layer by layer.

The only regulated parts (I know of) are:

• receiver (considered the actual gun, this is the bit they print)

• suppressors (not printable but you can make these homemade, though not as good and definitely not as reliable.)

• autosears (or anything else that makes your gun fully automatic, or even act like it, usually these are super basic and printable)

• big magazines (not federal but a lot of states have laws on em' Usually states with these laws will allow big ones to be sold with rivets, so they can usually be converted with a drill and new spring. Also they're just boxes w/ springs so you can print one.)

They're also starting to Anodize rifling into barrels using cheap 3D printed jigs, so some of the metal parts are now getting homemade too.

The components aren't traceable either. They don't have serial numbers on them. Typically only the lower receiver does. This is why that's the part that's typically 3D-printed.

Those would hard to teace and yu can pay cash. How many stores sell metal pipe withthe same inner diameter as a 45 caliber. It would be lole tracing meth lab by ammonia sales.

That’s true

gotta count how many fingers it took to pull the trigger

really easy to tell if an image is AI or not still it's not that good yet

Factually, they illegally searched his bag without a warrant at the mcdonald's, repacked the bag, put the bag in a police vehicle and drove to the police station without bodycam, and then turned bodycam back on to search the bag again and instantly "find" the ghost gun in his bag, which, without a serial number, is conveniently impossible to prove it was not planted.

The motion goes on the state that once that officer’s body cam footage resumes, it shows her immediately re-opening and closing the backpack compartments she already searched and then opening the front compartment of the backpack “as if she was specifically looking for something. Instantly, she ‘found’ a handgun in the front compartment.”
