Who said anything about removing usage limits? If past experience is any indication, this will just let people reach their limits faster. Does Verizon even have limits on uploads, or is it up and down all lumped together?
Everyone knows the best laws are the ones rushed through the commons and passed on the nod in the other place.
From TFA:
Mr Cameron said: "We face real and credible threats to our security from serious and organised crime, from the activity of paedophiles, from the collapse of Syria, the growth of Isis in Iraq and al Shabab in East Africa."
Paedophiles are a threat to national security now? Organised crime? Maybe, but for heaven's sake how stupid does this government think we are, that we would swallow yet another use of pedophiles as the bogeymen du jour? That was a rhetorical question, it's not a question of stupidity as much as it is voter apathy coming back to bite us in our collective backside. Again.
If it is large enough, why not move the laser instead?
In an SLM machine you have a cavity that is filled with a fine metal powder, the laser selectively melts/sinters parts of that, the base of the cavity moves down slightly and more powder is added to the top. Rinse and repeat until you have a solid part in the cavity surrounded by the powder that wasn't touched by the laser. I'm not going to cop-out and give a link to wikipedia, but if you go there and only look at the block diagram you'll see why the bed needs to be moved with precision at least equal to the minimum feature size that you're aiming for.
What this project aims to achieve is akin to 3D printed plastics where the raw material is deposited right where it needs to be instead of selectively converting parts of a much larger amount of feedstock. I suppose you could move the laser if you want, but it on the face of it I think it would be simpler to just use a few mirrors attached to servos to direct the beam where it needs to go.
Everyone makes awful, sputtered welds on their first few tries. Being able to lay down a good bead is not a skill that comes easily, not least of all when you're trying to build a machine that can do it from scratch.
The top of his blog post says "using... a TIG machine". TIG welding is not the same as MIG welding: with MIG the wire is one of the electrodes and is fed using a variable speed motor through the torch, with TIG the wire is held separately in one hand in much the same way as it is with brazing and the torch is in the other hand. I think he's used parts of a TIG welding machine because that's what he happened to have. There's no reason I can think of why the same couldn't be accomplished using a MIG welder.
Of course this would be easily settled if the video showed the machine in action or the blog had any sort of description or diagram of how the machine works on either of the two pages.
Welding identical parts with predictable properties in the same places is one thing, and robots are ideal for it*. So long as there's a need for custom fabrication and patching damaged parts there will be work for human welders.
*Probably why many earlier robots were used for just that, although spot-welding rather than arc.
I'm not sure what you're saying here. If you mean that the word "sintering" is used mainly when plastics are involved then I'm afraid you're mistaken. It's used when referring to sintering as opposed to melting; melting and sintering are quite different and produce very different finished parts. The question of whether plastics or metals are normally sintered or melted is unrelated.
Why would there be any size limitations to laser sintering?
Because the bed holding the part and the powder that's going to be sintered needs to be moved with very good precision. It also needs to be at least as deep as the part you're making. It's generally very difficult to get large things to move small distances.
Not much, I suspect. Starbucks are a lot like McDonalds in that uniformity will always take precedence over creativity. It may not be the best coffee/burger, but the customer always knows what to expect.
Unpleasantness is relative. Have you watched Saturday night TV recently? At least when I had my wisdom teeth out there was a sense of relief at the end; the same cannot be said for something like Britain's Got Talent.
You need an account to get these messages? It's an open-and-shut case of spam then, because I'd never heard about LinkedIn until my inbox started filling up with messages from them.
No, I really don't have any link to the people who are supposedly sending this crap. I even get them on an address that I've never shared with another real person.

So, in other words, what you're saying is that bread bakes you?
Incinerating the thief is all well and good but I'd sooner have a car that doesn't bifurcate then burst into flames in the process.

Now if only YT could stop defaulting to 240p on every video I play...
I still remember my CD key for Q3.

Just as, nowadays, there's a difference between talking about "gay people" and talking about "the gays"?
Not to me, and I am one of them.
"One of them", however, gives me pause as the us vs. them mentality always seems to end badly.
You'd do better if you charged a million.

Top of his blog it says TIG.

I really wish they'd stuck with calling it "rapid prototyping".

Laser sintering is commonly used the term when plastic parts are produced: https://www.additively.com/en/...

I get LinkedIn spam from people I've never heard of.
The ones you mention are American companies and thus does not have to follow European law...
...unless they trade in Europe.
I'll bet that the charts will be just as badly rigged as they are now.
If the FCC is seemingly so impotent to regulate the industry, just what the hell are you guys paying it to do?
