For more insanity, it was initially suggested to be a return to launch site (RTLS) abort test. The mission commander shut that down in a hurry. I've always thought it was interesting that Buran could fly autonomously while the Shuttle

That's a good point about scaling. They're not trying to build 50 of them right now, just a handful of prototypes. And AM is particularly well suited to that.

While I'm not convinced on the utility of 3D printing a cylinder (I think they have plans for more complicated lifting body type shapes in the future), it's great to see more players in the game! As an aside, I'd love to know

Thank you for correcting me. That's a deep rabbit hole

Oral vs. sign is a big ongoing debate in the deaf education world. Different schools have different schools of thought.

ASL is based on French, so the structure is completely different.

In the context of standardized testing, sure. I don't think I'd try that in a research paper.

Honest question: for someone who doesn’t live in a terminal, what does something like this do that a default terminal with OhMyZsh doesn’t do?

That's why I specified an industrial machine. No fab shop is going to use a 20% duty cycle machine. Granted, you can weld just as well with a cheap machine.

by metal_am 4y ago
Wire and gas costs aren't the issue. It's the cost of the welding machine because only one person can use it at a time. You can buy multiples of these for the cost of one industrial machine.

This is definitely done in the research world. The flash/brightness from the arc isn't an issue because it's a different wavelength (UV vs. IR).

This is where the most promising applications have shown up (but not necessarily the money). It’s fantastic for things like assembling wiring harnesses for aviation where it can serve as a sort of interactive manual.

This particular research is literally built off of weapons research (National Ignition Facility).

Depending on previous questions, it will straight up answer this question as well as giving step by step instructions on how to make explosives.

This. And it will confidently give those answers.

The idea is additive manufacturing allows for more complex internal geometries, i.e. cooling channels.

by metal_am 4y ago
This is a huge field in additive manufacturing. One of the most promising solutions is in-situ process monitoring to identify defects that may occur, often using machine learning.

Reading between the lines, it seems like this is intended for high quality steels. Think aerospace, not buildings. Actually in those applications, you don't really want carbon. The strongest steels have virtually no carbon. Hydrogen em

It produces an intermediate product. You can't use it without further processing. In any case, the hydrogen won't be a problem.

Steel is an incredible massive category. For high quality steels (duplex, maraging, PH stainless), you actually don't want much carbon. Since they talk about "aging properties" in the article, I'd imagine they're ta

Looks like we're seeing basically a recording of what you'd see at the microscope, just not in real time. The video is way sped up.

I’m really wondering about this too. If it were an OEM or service provider, I would expect them to advertise the capabilities of their brand/company.

Airport scanners are not CT. They will only give you one projection. I would also be willing to bet these CT machines can only scan a very small volume. Typically, they will rotate the sample, not the X-ray source and detector. I’d imagine

It’s the chromium. Cookware usually has nickel too. When a pan is advertised as 18-8, they mean roughly 18%Cr-8%Ni. Basically the same as 304 stainless steel. You have molybdenum additions in something like 316 stainless steel.

It's dirt cheap and incredible versatile. It has many different crystal structures that can give you an incredibly wide range of properties. General purpose mild steel used in buildings. Stainless steel that resists corrosion. Maraging
