reminds me of Delta 3D printers. Quite genius, but seems the arms/legs/elbows of this might collide with the working surface, although the "platform" could just be made taller to compensate. Won't want it to be too heavy though, as it would lose speed.

Some of the more recent United States Governmental statistics indicate that about 2% of elementary schools in the U.S. use metal detectors, 7% of middle schools, and 10% of high schools. This is a fairly low number, with literally only 1-in-10 high schools utilizing metal detectors within the country. Aug 13, 2019

I understand that "probably" all school shootings have been committed by real students. Students with hatred issues, respect issues, power issues or whatever. She got away with acting as a student and penetrating the security or lack of it. Granted I can't see just anyone getting away with her plan by "acting" as a student but she was able to gain unfettered access.

With 3D printers getting more sophisticated, metal detectors are not a catch all. I also think there can be better ways to recognise mental issues earlier to reduce the threat of would be killers. It's not foolproof but after a shooting there were usually signs of a violent nature of the shooter before hand.

Yes she may be a criminal but she was unarmed and had no violent intentions and was aware of the risks of her actions but still felt more was needed to be done. I believe more needs to be done keeping the public safe from people that want to cause harm just because they have the power to do it. That includes bullies who don't pick up guns but rather create rage in innocent people.

My initial comment was due to @jimnms comment which seemed to imply the woman was merely an attention whore and overlooked what her real intentions may have been.

EDIT: I also think your decision to not have children and perhaps grandchildren could have a HUGE impact on reducing the number of children killed or wounded anywhere in the world. If only...

You need to do some more research, there are some terrible bills out there in addition to ones with straightforward good things like background checks. The ghost gun fanatics will end up banning aluminum stock and most 3D printers, they are so ignorant.

Ghost gun "kits" like you say are blocks of aluminum or polymer partially machined that have to be further machined to be turned into a gun. Cad files for turning a rectangular block of aluminum into a gun are easily available. These are not guns, and treating them as such is simply stupid.

Firearm accessories like magazines are critical parts to a functioning weapon. People have already been successful in getting most people to think 30rnd mags for an AR-15 is "high capacity" when it's actually the standard capacity. They want to ban every removable magazine, with zero data that it will reduce gun crime. There have been bills to define any semi-automatic weapon an "assault weapon". Ludicrous.

I loved this. Wish i had me a 3d printer. Helping locally is very cool. *promote

I'll bet none of those 3d printer files were authorized, I mean, you wouldn't steal a car, would you... would you?

No. I mean 3D printers. Otherwise the joke doesn't work, despite how lame it might be.

If I have to let you know I'm joking, I insult your sense of humor.

No insult intended.

Amazing what you can do with 3D printers these days.

Found these on Amazon awhile back while modding my 3D printer and, since I've never really done much soldering, these seemed like a cool idea and they work great.

Good point, but not exactly right.
Plastic guns, yeah, not so scary here in the U.S. where anyone can get an unregistered gun in hours, but in other countries where guns are rare, this gives criminals access to better weapons than the general public, or in many cases better than average police carry.
Also-
There are both 3d printers that can print metal and the guy putting the plans out has a business making small cnc milling machines that can mill guns from his plans in steel. That means these guns can be exactly the same quality as licenced manufacturers make. I would bet there are or will be plans for fully automatic weapons as well.

One thing I do agree with that annoying douchebag on, is that you can’t put the genie back in the bottle. If 3D printer gun models are out there (and I don’t doubt they are) it’s going to be very difficult to stop that information for spreading.

*quality fun.
I wonder if they'll have a subscription model allowing people with their own 3d printers to print updates/new models.

Your video, Engineer Guy - Bottom Up 3D Printer, has made it into the Top 15 New Videos listing. Congratulations on your achievement. For your contribution you have been awarded 1 Power Point.

I don't, man - I don't hear what you're hearing haha - his tone sort of gives it away but, yes - he could have been more clear that what Glowforge calls a "3d Laser printer" is a mis-classification since it is a 3D printer. I didn't find that interesting, though. What I found interesting was that media groups have been scaring people on the topic of using 3D printers in their homes and in this case the pinter that killed these poor people was not a regular desktop 3d printer. Which are pretty damn safe if used close to an open window with a fan/ventilation.

Damn, saying the same shit over and over again - like talking about taxes all day lol

That's how I take him saying "a magical device that doesn't exist". If he means 'stop calling it something it isn't', he should say those words instead of what he said, no?

Edit: I don't disagree with his assertion that 3d printers don't make CO, or his frustration that cutters are being called printers, just his saying laser printers are non existent or magic.
