Small caliber, lots of plastic, short lifespan, unreliable. Most serious 3D printed guns have at least a metal barrel. Often, 3D printed guns are just a lower receiver, that is the part you hold in your hand, the parts that actually fire the bullets (barrel, pin, slide, etc...) are bought off the shelf from real gun manufacturers. This is a workaround for some laws that considers gun parts to not be a gun. For exampl…

I think this is why 3D printed guns have not been an issue in Australia. Since you couldn't easily buy all the metal parts you still need.

They aren't really an issue anywhere because if someone really wants a legit gun they are not that hard to buy on the blackmarket or even produce yourself. There just isn't much actual demand for 3d printed guns, people do it because its fun and an engineering challenge. If someone can buy a tabletop mill or lathe, or if they are patient with a file, we have 100+ years of well documented and engineered gun designs anyone can copy. Like you are seriously only cutting a couple hundred bucks off the price between buying a 3d printer or a CNC mill and all the CAD files you need for either version are easily accessible online.

I got a Bambu A1 Mini a few weeks ago and it's practically easier than 2D printing. Printed a whole tabletop game that I played with friends, and replacement parts for a gun that held up at the range.

Wow I’ve heard about these 3d printed guns mostly in the context of the gun control debate. I can’t wrap my head around “how does plastic stuff withstand the stresses of a bullet?”

Most "ghost guns" use factory made parts for pressure bearing components.

US is a rare country that treats only serialized parts as "guns" and don't regulate actual gun parts. This allow Americans to trivially "build guns at home", but easd of actually building guns is extremely exaggerated.

Also, there's little in 3D printers that actually makes it easy to build gun parts. It's all cosmetics. Real illegal ghost guns are always made with plumbing supplies.

I'm not changing out nozzles daily, but I do sometimes make small parts that need the .2mm nozzle. Not for gaming or miniatures, but typically mechanical interfaces where the .2mm nozzle gives a better result. But then for most stuff I use a .6mm high flow nozzle.

It's worth noting though that this part of the game is about to change majorly for both brands. Prusa is widely known to launch their next-generation tool changer at Formnext in Nov, which is going to be a concept where you have a rack of nozzle+heatpipe+filament tube tools that the print head grabs and heats up inductively. And Bambu is more or less working on something similar they will probably launch some time ne…

Maybe because you're incorrect about the AMS being the problem? The AMS merely feeds the correct filament. It's not the fault of the AMS that the printer doesn't have multiple nozzles.

Prusa is going to use Bondtech's upcoming INDX system, which swaps out the entire filament path.

Bambu Vortek seems to just be swapping nozzles so, while that should cut down on waste, it's going to be much slower (XL is already much faster than AMS based printers but comes at a substantial price increase).

INDX tool changes are expected to be around 8-12 seconds. Vortek would be probably be around 30+ seconds.

What bambulab printers that have the "A1" series nozzle, replacing one is a matter of 3 seconds, just by naked hands. 10x times faster than in the Prusa world (Nextruder included). Being this the single most important thing a printer need from the POV of servicing, this is a huge difference.

How often are you changing nozzles? I can't think I've ever done it except for swapping out the manufacturer supplied brass with a hardened steel after or arrives

For tabletop gaming I'm switching between nozzles pretty regularly, so I can have fine detail on small minatures and faster prints for bigger terrain, bases, scatter and grid pieces.

Your comment seems to rely on the premise that the only alternative to everybody's acting 100% selfish 100% of the time is everybody's (or at least my) giving up their property rights and privacy. I wasn't suggesting anything like that or even trying to pressure anyone into not being selfish: I merely pointed out that a sentence on the internet[1] would be untrue if anyone cares about Bambu's policies and practices f…

No, my comment relies on the premise that devices on the internet are targets for attacks and nearly impossible to secure. I maintain dozens of servers on the internet.

LAN mode still works on my A1 & I can access it from Orca Slicer just fine.

I've been unable to connect Orca Slicer to my A1 mini over LAN and I'm led to believe that as a result of that firmware update it is impossible. It's possible something else went wrong and I just gave up because of a misunderstanding I guess? Are you sure you aren't just running older firmware (my A1 mini is a recent acquisition)?
