Shrinkage factors are accounted for during development of the tool.
I like molding with abs for a few reasons, but ease of ejection isn't one of them.
A properly designed tool can eject it's parts with only enough shrinkage to release a surface texture, and even then we rely on draft angle.
That all being said, I walked in here thinking abs would be nice to use, for previously mentioned properties. Do you guys have any more links or information to alternatives that I can read?
I'm very much new and totally inexperienced with 3d printing.
