Making 3D printing truly 3D

So this is voxel printing. But after reading the article I still don't get why the resin only cures at the focal point and not in the beam. To me it's also unclear what the red laser has to do with it.

As I understand the red laser hits the beam and then creates the focalpoint/ blue dot.

Ah yes. Zbrozek posted a better link in this thread.

Two lasers cross and at that point the nanoparticles in the resin help to focus the light and cure the resin at that point.

No. They have a single laser source that converges at the point.

It doesn't seem to say whether they move the laser source in 3D near the tank, or just in 2D and vary its focal distance.
