Everyone always thinks the jewelry when they think of diamonds but I am excited for the prospects of what cheap lab-grown diamonds can do for manufacturing. Diamonds are electrically insulative and yet 10 times more thermally conductive than copper. There are a LOT of industries that would be VERY interested in that.
Hell, it would probably be useful in CPU substrate as well. Instead of silicon semi conductor doping if these could be made precisely enough you could use diamond for the insulation layers and gain that insane heat transfer efficiency to help with avoiding Hotspots. Maybe that’s too thin to matter that much not sure
Silicon carbide is much more interesting for the semiconductor industry. With pure carbon there is a lot of lattice mismatch between diamond and single crystal silicon which introduces strain and defects, both of which reduce yield in chip manufacturing.
Similar conditions are employed in the method currently used to synthesize 99% of all artificially created diamonds. Called high-pressure and high-temperature (HPHT) growth, this method uses these extreme settings to coax carbon dissolved in liquid metals, like iron, to convert it to diamond around a small seed, or starter diamond.
Cool. I don’t know how expensive this process is right now, but it seems cheaper to do, at least on mass production.
Edit: I wonder if they could make a tether out of this thing.
Folks like de beers hoard diamonds and jack up prices to make folks think they are more rare that what they really are. We gotta stop the cycle and buy lab grown or use an entirely different stone all together. Diamonds are for basic bitches anyhow
I got my wife a antique sapphire ring to replace the engagement ring that was stolen in a burglary. When the sun hits that jem, it’s like staring into the deepest clear ocean. I was in the Navy and remember when we were coming to port in Honolulu. The water was the bluest blue I’d ever seen. Old sapphire gives me the same feels
Recommend looking into moissanite also if you like diamonds but don’t want to support the industry. Very similar looking, better in some ways. And because it hardly occurs naturally at all, you can only buy synthetic.
What I wanted to convey is, if the mesh is fine enough, the pattern can get marked on the skin, leaving an elegant but discreet - shall we call it - love brand behind.
If you’re going to cheat, at least be bold enough about it and keep the wedding band on.
That is the sole thing I draw the line. Scynical as it may sound, ink on skin, no. It feels as an ownership brand that can never be taken off or thrown away.
I personally dislike the notion of being permanent on another life. Either because things don’t work, people grow apart or someone simply dies, from misfortune, sickness or old age, nobody should be tied to another, in any way. Life should go on. Must.
Compared to their artificially inflated price. They’re obviously useful in industry - mainly for their thermal conductivity and their hardness - but their price as a jewel is complete bullshit. They’re not rare at all in nature, but one company controls all of them and uses advertising to drive up demand and public perception.
Either JPL or LM (I can’t remember which) was working on a HTHP system with the goal of being able to grow diamonds with ICs built in. I wonder if this has that potential.
Carbon, compressed hard enough it becomes diamond, forms a square crystal lattice that is so crazy stable that it’s very resistant to change (including from burning).
I don’t know specific temps, but graphite forms a hexagonal lattice that is highly stable on 2 dimensions. The bonds between layers of hexagons are weaker which lets it be brittle in all the ways we love graphite. I’m not sure how this specific geometry changes the affinity to bond to oxygen.
they are small, but the large diamonds are made from seeds, so still can be used for that, or techniques can improve for larger size production in the future, also, small diamonds are useful for cutting machines
I have a tungsten steel nozzle on mine and it’s been good for a long time, I imagine it’ll run forever. Does anybody have experience with the diamond ones? Are they worth the extra expense?
I haven’t tried them myself but they have (at least in theory) a lot of benefits speaking for them.
You won’t wear them out, no matter how abrasive your filament is. At least until you print diamonds I guess.
Diamond conducts heat so much better than any other material you might make nozzles from it’s hard to believe. You might (or will) run your prints way cooler, or faster.
Several other things I won’t explain here because I have no idea and would have to make them up on the spot. But how cool would it be to print with a poly crystalline diamond nozzle? I bet you’d drown in panties.
Looking into it, these are very fragile nozzles. Even more so than the ruby ones. The Tungsten nozzles are the true robust nozzle. It will wear out if you’re using filament with abrasive materials but it takes a lot to do it. I’m going to keep it in mind but probably won’t consider it
However, the new method has its own challenges. One problem is that the diamonds grown with this technique are tiny; the largest ones are hundreds of thousands of times smaller than the ones grown with HPHT. That makes them too small to be used as jewels.
Just wear hundreds of thousands of them glued together, problem solved.
On a more realistic note though, the applications of this will probably be industrial for a good while. I found it interesting how the article mentions that they were able to develop a diamond coating over their growth substrate. That probably has some cool applications in industrial settings where diamond-plated materials are used.
It depends; if a company can use this to make them stupid cheap, then selling them stupid cheap to undercut all their competitors could still make them more money than keeping the price the same and pocketing the saved production costs.
I was making a jab. I’m aware of market forces, but price memory is a thing and often the true cost of production isn’t reflected in consumer pricing. Especially when an industry just decides they can keep prices where they are if not raise them, looking at you egg producers.
