Hello, looking for advice on which Filament types are best suited for RC Submarine builds?
Best 3D Printing Filament Type?

Nothing special for me! I have 5 3D printed submarines, and 3 more in the works right now! I use Solutech White PLA! With proper printing at 100% infill, and no special treatment! Light sanding, sanding primers inside and out (I use two kinds of primer) flat final color finishes, and matt or flat on the clear coats. I make sure not to keep the subs out in very hot temperatures! During the summer heat (Arizona) my sub runs are about 10 to 15 min. then back in the cool!
This has worked very well for me. I run all my subs in the swimming pool only!

The other reason I like Solutech WHITE PLA is it gives off very little if any of the fumes that some of these special filaments give off! So that allows me to print inside my office/shop without dealing with the fume factors! PLA needs a little more finessing, but it works great for me!

This thread has produced valuable information. I can’t help but wonder if 3D printing information is scattered thruought the forums here? Is there a key search word to find this information? If not maybe 3D printing deserves a category of its own?Comment

I do it for that reason and because there is often just enough porosity in a print to allow water into at least some of the air pockets thus trapping it. I printed just the 6 outer most perimeters on my Columbia because I modelled it in solid sections. By doing that there is no porosity created by the back and forth zig-zag of the print head as it is just concentric rings. I do realize not all subjects would lend themselves to being printed that way though.Comment

Printing without 100% infill will absolutely eventually allow water to enter the interior voids, which changes buoyancy. Water will be trapped there. You'll see a gradual reduction in buoyancy, followed by hours, if not days, of your sub leaking water onto your bench after you run it.
I know this from past experience. Don't cheap out on time or material. Print solid parts.
