What is a major benefit of soluble support structures like WaterWorks?

The major benefit of using soluble support structures like WaterWorks is that they allow the creation of very intricate designs. With soluble supports, complex geometries that would be difficult to print with traditional support materials can be easily managed. This capability enables designers to create parts with overhangs, internal cavities, and detailed features without worrying about the limitations typically associated with conventional supports.

In contrast to the other options, while soluble supports might have some impact on material costs and potentially reduce the time spent on post-processing, their primary strength lies in enhancing design freedom. The ability to remove supports easily without damaging the model allows for a greater range of design possibilities, making it essential for intricate and detailed prints in more advanced additive manufacturing applications.
