This machine exposes the photoresist on a die to define patterns. A maskless process is one where an arbitrary image can be displayed instead of a fixed mask. Essentially, this is a reverse projector: Instead of making the image larger, it is made smaller, focused down onto the die. Usually, it is also necessary to use UV light.

Here are a few links to existing setups from other people:
