Because if it works it enables greater control and consistency, clean borders for the sensitizer, possibly lower sensitizer utilization, and customized shaping and sizing of sensitized areas. And, it means anyone who then wants to dedicate an old printer to the job can do so as well, (again assuming it works.)

If it does not work, I lose a small amount of money thrown into the experiment, which is no big deal.

Besides isn't at least part of the fun of alternate processes performing experiments. If I stay safely within the borders of the known, the boundaries remain fixed, but if I push at those boundaries I may find a way to better achieve my vision.
