I am using a Formlabs 3 resin printer and I am would like to create a bottle design with a cap. my objective is for the cap to completely prevent any liquid from going in or out of the bottle (even it was shaken) and also prevent dry air from seeping in and effecting the moisture inside.
(Note: I am not planning to cure my print with UV light as I feel it ruins the smoothness and flexibility of the model. tell me if I am wrong)
Is that possible by just printing? or do I need some coatings or extra steps?
