I wonder about ABS? I know that Voron printers use that for the functional parts.

This sounds a lot more viable to me than fancy resin solutions (I could be wrong).
Printing with any filament still gives parts that grainy weakness to it (like breaking wood on the grain, but much easier). I tried printing a part with 100% infill and it still a part of it snapped off with ease right on the grain. Though parts which complete a type of defined solid shape such as a cube, or sphere are much better. When you have mechanical shapes like if you printed a hammer for example, there would be weak points.
The resin solution is for making the molds for low volume injection runs. The idea is you don't have to spend a fortune for metal molds which are designed for very high production runs in the millions. The resin ones would last long enough to make a few hundred items.
