Can you 3D Print a fully waterproof part? Titan, Titanic or Nautilus results at 200 ft depth test?

I have been having trouble finding a way to prototype waterproof parts - this is one of the original reasons I purchased a resin printer, but I am now finally testing it! I used the resin printer to print a sphere with a 0.200" wall and a 0.25" neck wall thickness and tested it to 90psi to see if there were any air leaks. Please comment and let me know what you think or what I should try next!
Here's a quick video showing most of the build process for the mechanical components of the Buster Beagle MK3 DIY Desktop Pneumatic Injection Molding Machine.

I fully support the dirty cleaning bath

This is my favorite comment I’ve ever received! Thank you, @rylis2! Maybe I can send the IPA to a CZcamsr that wants to demonstrate how to clean it 😂

You do realize you’re making a bomb?

Haha! Yes, I 100* realize that. But it is only air pressure at 100psi. Not a huge risk for that tiny volume. Basically a large air hose. Haha. If I go any higher in pressure I will fill it with liquid and pressurize air only at the neck (hydro test) so if it explodes it will not have any pneumatic compression behind it.
