Etched sheets like this have been used to make rocket engine thrust chambers. Holes for coolant channels are etched into the sheets, then the sheets are stacked and diffusion bonded together.

Anyone working in the hard-tech sector eventually hits the point where clever ideas alone aren't enough to make progress, and you need something made that seemingly is beyond the reach of even an advanced and well-funded prototyping facility. You know that the part you want is makeable; you know similar parts are found in even mass-produced consumer equipment (eg. inkjet printer nozzles), and yet even with a sizeable budget it's hard to find anyone who can make what you need to even test your idea without months of lead time at the minimum.

That's why Applied Science's channel is absolutely fantastic. It's amazing how he elegantly pulls centuries of know-how together (along with an eagerness to get his hands dirty) to make just about anything that's within the reach of today's high technology, in what appears to be a garage. And makes it look easy.
