On today’s episode of Uncanny Valley, we discuss how WIRED was able to legally 3D-print the same gun allegedly used by Luigi Mangione, and where US law stands on the technology.

And they wirk with more than plastic. I have had that conversation several times. People honestly think all 3d printers can do is cheap plastic.
What else do they work with?
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.
Some mad scientist in Scotland claims to have gotten his printing stem cells. He’s trying to figure out how to print replacement organs that have no chance of rejection
Link? That sounds dope as fuck
Since I saw the original article somewhere around 2010-2016, and am unable to find the original article, here are a few articles that seem to indicate that he might not have been as “mad” as I first indicated.

That last article is certainly promising, since if it is possible to print stem cells, then it follows that organ replication, with the right environment providing the correct hormones, should make this technology a viable replacement option for the rich, or the masses once the old prophecies about humanity surviving its stupidity have come to pass in the next couple decades.
Oh yeah, I forget about sintered metal printers. Which is funny because that’s one of the first ones I saw.
biocompatible bone too
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.
I saw an sls printer make a copy of ironman’s suit. It was crazy thin and highly detail pieces. Add some paint abd it look just like the movie.
I never understood why they never just bundled a bunch of carbon composite front loader barrels with electric ignition along with a laser pointer. No need for any metal nor 3d printing.
I really don’t think these would withstand the pressure,tbh. At least as long as you mean 3D printed ones.
No, just laminated ones. Closed at one end. Easy enough to make or buy. You can even improvise the propellant.
Carbon fibre is a big one.
