Notice how they drop the Z axis to go from “cut” to “bend”, and raise back up to finish the cuts? Out of focus to heat a wider area without cutting through. You can set your bend radius by calibrating how far to raise and lower the bed. Very interesting stuff.
In a practical sense, the raster bent surfaces don’t do anything that can’t be done much more efficiently by the hot element acrylic benders I used in high school… And I hate to see the extra hours put into the laser consumables that could be done with a hot wire or ceramic rod in less time.
