  1. They aren't brands. Many of these boards are designed by community members like you and me and are just sold through the known vendors to make it easier for the designer.
    That's why you won't necessarily find a website for all those names.
  2. Yes a lot of these boards are limited run items, simply because it's not economically viable to mass produce such niche products. Production of them is very expensive and the market is very very limited. To keep production costs to a somewhat manageable level for both the designer and the vendor they are only made in preorder batches.
  3. It's not "just aluminium". They are CNC machined components that often times have very complex designs.
    CNC machining is extremely expensive, especially for low-volume production like it's usually done with keyboards like this.
    And even raw aluminium prices are currently through the roof due to the ongoing economical problems.
  4. In some cases there is artificial scarcity and price gouging (like with Keycult or TGR boards for example).
    But most of the smaller lesser known groupbuys are absolutely realistic prices.
    As mentioned CNC machining for low volume production is expensive af and mass production is just not reasonable for a product that has such a small niche market.

If you want fast availability and shipping the super high-end boutique keyboards aren't for you.
Those are more something for collectors that have patience and no problem with waiting for a product for a year to get something unique.

And you honestly don't have to get one of those if you just want to build a good custom keyboard.
There are quite a few easily available options now that are still very much high-end.
This hobby has seen a rapid growth over the past two years and there are quite a few vendors that produce boards now that are good quality and usually in stock (or at least restocked frequently).

KBDfans, Keychron and Cannonkeys for example all have several beginner oriented keyboard series (both alu and plastic) that are easily available.

I have a degree in sculpture and specialize in digital fabrication. Unpopular opinion, but CNC machined aluminum is overkill for most keyboards. It makes sense on highly stressed components or complex shapes, but most people aren’t doing kickflips on their Zoom65. Investment casting is a lot more cost effective at scale and doesn’t need a ton of cleanup if you’re just going to electrophoretically coat it afterwards. There are plenty of factories in Vietnam that will cast high-quality parts at a lower cost than their Chinese competitors.

I’d personally rather see more innovation in PCB design though, as the custom scene really has been sleeping on things like USB pass through and whatnot.

Yes of course it's completely overkill for a keyboard.
Pretty much all keyboards around in this community are overkill.

But like you said for small scale production CNC really is the most sensible route if you want the case to be made out of metal.
Casting only makes sense if you are going to mass produce the product which doesn't apply to most custom keyboards simply because the market for them is too small.
No company in their right mind is going to invest tens of thousands of dollars into prototyping and manufacturing metal casting molds for a board that will maybe sell a thousand units at best.

As for the PCB:
Some designers have tried to do stuff like USB passthrough but many people here just don't really seem to want that kinda stuff on a high-end boutique board.
And since those PCBs are a hell of a lot harder to design and also more expensive to manufacture most custom PCB makers just decided to not go that route.

I was referring to investment casting, which does not involve producing permanent molds. The molds are made of ceramic and are shattered with thermal shock to release them. It’s similar to sand casting, but with a much smoother finish. Common technique for manufacturing high-end cast iron, jewelry, and bronze sculptures.

I would guess that this would be much more expensive than just CNC machining.
Especially with the size and geometry that some of the higher end boards have on the inside.

And it would probably still required at least some finishing in a CNC machine.
Screw holes will have to get drilled and tapped and the mating surfaces between parts have to be absolutely flat to not create any visible gaps in the assembled part.

And with casting the QC process is usually much more involved than with CNC machining since a casting can fail a lot easier than a CNC program.
