With this, the scanning beam is not directed at any single spot, but moves around, so the plastic does not burn.

To do that requires scanning the object beam through the target about a hundred different ways.

It works by scanning a laser beam across an object and manipulating the reflected light to produce an extremely narrow focal plane.
