Hollowing suppresses cavities narrower than the closing distance threshold, and it also fills in sharp concave corners of the inner wall, from which it would otherwise be difficult to remove the uncured highly viscous resin. A trade-off between accuracy and performance. Share it with us! It also is very stable and durable once you cure it completely. If its still sticky after that, give it a few more minutes in the IPA. You can use a syringe to push alcohol through the holes. It is also worth mentioning that not all resin is cured right after 3D printing process.Although, we have solid object there is still uncured resin within the 3D printed part.

Wall thickness is the distance between the outer surface of your model and the opposite inner surface. Too much exposure to IPA. This is because the resin trapped in the cavity will be at a higher pressure. We could add air access or resin vent, but we could also just put the missing wall to be facing in X or Y and then angle the item ever so slightly to give the item good resin drainage and totally avoid the need for an extra hole in a surface we want to retain.

If no drain holes are added, hollow models can become quite heavy with liquid resin trapped inside, causing adhesion issues that may lead to failed prints.
