1:35 AND I bet you could drill into the bottom of your 3d printed heatsink, and epoxy in a copper slug, I wonder if that would help or hurt it. I know PC heatsinks often do a similar approach.
Heat sinks seem like the absolute ideal usecase for metal printing! I have to try that sometime. So far I have only bought aluminum milling, which is priced pretty similarly from those *pcb companies. I was always worried that metal printing would be more brittle in mechanical applications.
First
8:09 Black Cherry in a glass bottle? I bet that tastes GOOD. Lucky!
Boylan is the best
OOOOOH PCBway. Yeah, I was like WHOA! Rinoa has a SLS machine???
Doesn't matter.
There's like metal powder infused spools which you can put in a scorcher/whatever high heat heating contraption.
That'll allow you to essentially make metal parts outta fdm prints.
@@yasirrakhurrafat1142 I doubt very much it's as good as laser sintering. That's effectively molecular welding. Not quite, but damn close.
@@mattparker9726 nah, I mean the fdm thing isn't quite that great.
God I wish I had a sls printer!
@@yasirrakhurrafat1142 there was a company 20 years ago that had an article in Popular Mechanics about making a sub 1000 dollar table top SLS machine, but suspicious enough, about a month later, I heard nothing, I think they were bought up.
Aluminium 3D printing? Wow, this technology went far so fast. Supercool. :)
Where did you get this crazy ideas of what you do with these heatsink stuff i don't have the time for this, you take this very hardworking things I won't do. This Is best video ever-DLH
Thanks for not calling your sanding, lapping. It always annoys me when people claim to be lapping with sandpaper. And there seem to be tons of people who genuinely don't know the difference.
I have no opinion on the matter since sandpaper is just another way to convey polishing compound once it gets to really high fineness numbers
LoL mate.
Would you call lapping.. sanding, as it can very well be done with high enough grit sandpaper?
Although you're not wrong.
@@yasirrakhurrafat1142 that is false, lapping is done with a loose abrasive while sanding is done with a abrasive on a carrier film. Lapping works by having the abrasive roll between the part and the lapping plate that is the reason so remarkably good surfaces can be achieved.
@@scruffy3121 okey!
There's a difference.
I'd have to venture into the world of precise machining to get a good grasp of it it seems.
great demonstration , thanks
Awesome design!
Hi Rinoa! What thermal imaging camera did you use here?
Therm-App Hz
3:46 Once again, from building PCs, I would use thermal compound to fill in any gaps. I wonder if it will have a more pronounced effect due to the rough surface? I suspect so.
Well I did use thermal compound on the bottom
@@RinoaL yes I saw that later. You should do one without it, for comparison.
i was super interested in 3d printed heat sinks a few years ago, was trying to make a fractal one. after convection effects it's all about the Hausdorff dimension of the shape [similar problem to 'hearing the shape of a drum'] and i think you can make it arbitrarily high as long as the material can withstand it. also something about optimal branching ratios similar to lungs to optimize there. its a fun rabbit hole.
thanks for putting a name to that
@@RinoaL check out mandelbrot's book The Fractal Geometry of nature, it talks about this stuff in more detail [not heatsinks specifically but optimizing fractal shapes in general]
sadly I wouldnt have time to read that, too busy with work
I have so many questions. What if the chip is on the bottom of a device. Ive become fascinated with the insane heat the bottom of the PS4 Pro gives of, I believe its the memory chips specifically. Your tests show heatsinks pointed upwords allowing heat to disapait upwords but I wonder how the performance will change if upside down. Also can you start with a small base to make contact with the chip and expand the diameter outwords towards the top of the heatsink. Also does making the heatsink taller allow even more cooling. My dream would be to have a custom bottom of the ps4 that is a passive cooling heatsink that replaces the plastic bottom. Anyways great video.
Sounds like you might want to look into doing thermal simulations yourself with software or physical
@@RinoaL interesting, thank you for the reply, any software recommendations to get started with
@@djangosoftwaredeveloper If you find a good program for doing that please let me know! I haven't looked into it, just seen others use it from time to time.
@@RinoaL just saw a program called Creo parametric on a metal 3d print channel no idea what it costs but I'll look into it
Are you going to sell them?
Id like to make some sort of lamp that uses them and sell it as a product. I put the models on printables if you want it yourself though!
Doesn't discombobulate under manually administered kinetic impact, yay! Cool heatsinks. I love the elegant design - a thing of beauty is a joy for ever.
