It seems like this should be super easy to spot by outfitting X-ray machines with computer vision that can compare shapes/outlines from the X-ray image with a massive catalog of 3D printed gun schematics. Of course this would only help with assembled guns, but it's a step in the right direction.

Title doesn't (really) reflect that this was part of a test, and not that someone was found to have smuggled a 3D printed weapon in.

Also, the article does not mention whether or not ammunition was smuggled as well; I'd imagine that'd be harder to hide from a metal detector than plastic -- and the gun isn't much good without bullets.

Plastic firearms are harmless.

correction: "Plastic firearms are [currently] "harmless" [in the grander scheme of things and in most cases]."

AFAIK all current designs can only fire one bullet before breaking, making them pretty useless for most situations where someone would want one. The only legitimate threat they currently pose is targeted assassinations, and those are a non-issue if you don't have enemies. If you do, invest in bodyguards and private security instead of externalizing your security costs to tax payers.

I think the most absurd thing is worrying about planes these days. Passengers pre-9-11 are completely different than passengers post-9-11. Passengers now know to revolt against any hijackers, especially if they meet the criteria of a hijacker that would use the plane as a flying bomb. In fact, that is exactly what happened with the flight that went down in Pennsylvania. As soon as one passenger discovered what happened at the Twin Towers via their cell phone, they tried to take over the plane and averted disaster.

Plus, all that was done in the time before wifi on board. Nowadays, many people on a plane are using wifi to browse the internet, send email and chat. All those people have access to communications outside the plane, whereas in 9-11 pretty much no one did (at least not legally)

Heck, a repeat of 9-11 went out the door when they decided to lock the cockpit. Which, really, they should have done much earlier considering all the planes that were hijacked in the past and the previous attempt(s?) to use planes as weapons against buildings. I can think of at least one person who got as far as a plane, intending to have it flown into the White House, I believe, long before 9-11.

Really shoulda locked those doors....

Would it? Wouldn't the catalog be enormous, and the model could be from almost any angle? Not trying to call BS, I am not a computer vision expert, its just whenever someone says something like this I always wonder the actual feasibility.

I think it was in the 90s when I read about neural nets being used to correlate air plane type to a static silhouette (might have been radar) from any angle. Of course, airplanes can't be slightly modified and printed out in minutes, so I'm not sure this would work here, or how much of a PITA constantly retraining the neural net when new schematics are made would be.
