Dunno what the positional accuracy is like, but if this is truly 0.1um resolution...  Back in '98 TSMC was just releasing their 0.18um CMOS process and MEMS was just starting to appear.

This is potentially MEMS-scale 3D printing! For $5K!

I saw it (not running). I can believe that they have .1um theoretical positioning accuracy (probably counting microstepping, which is not reliably precise). The Z screw had a pretty fine pitch, though looked like it might have been a 2-start. Believe that it had a full-step travel distance of (approximately) 3.2um, which would make each microstep nominally .1um. I only saw the Z screw, but the X and Y are probably running on the same thing. I don't believe that the laser is focused to selectively cure a point that small (if it was, the cured point wouldn't be fused together). It's probably curing an area significantly larger than that, with a theoretical (assuming microstepping is reliably precise, which it isn't) positioning accuracy of.1um, which is much less impressive than it sounds.

Video for this "Wearable Futures" conference should be appearing on their YouTube channel over the next couple of days.  I only caught a few snippets of the live-streamed presentations, but they look to be very interesting.

Lots of 3DP content!

For future reference, particularly w.r.t designing 3d printable motors.

This could get interesting in the embedded computing space.
ARM has just purchased a gaming graphics technology outfit called Geomerics -- a name which may not ring a bell unless you're a particularly inquisitive
