PP Keyboard - Top Row Actuation

[wibble]

I would be surprised if they were using 3D printing for a large production run like this. My guess is the marks under the key cap are tool marks from when the molds were machined. Removing material from the keycap would require adding material to the mold, which I think means having to mill a new section of mold. I think it's probably less costly to source some adhesive mylar spacers to be added at the factory during assembly. Then again, I don't have experience with injection molding in a factory environment, and the change might be easier to make than I think.

I would have said the same until someone posted video in another thread detailing the use of 3d printing to reduce the cost of tooling for short production runs. The tooling apparently won't last long, but is cheap to make and to iterate improvements with. I'm just guessing though.
