That does indeed look like a good option. Especially since it can also be vapor smoothed with acetone like ABS to reduce the porosity and surface area.

<p>I've got a printer on the way later this year that's supposed to be able to do both FDM and SLA (with the appropriate accessories). I'm interested in printing some parts for swimming pools (the types that generally cost fifty cents to make, but with markup and shipping end up costing thirty or more dollars). </p>

<p>I need to find a material that can withstand exposure to chlorine (up to 15ppm for the rare nuclear shock) and UV from the sun, hopefully for several years.</p>

<p>I think that I'd prefer an FDM filament initially in order to test, but understand that FDM processes may require more post-processing in order to keep water from penetrating layers. </p>

<p>What are some other considerations that I should be aware of? Having a white color would be preferable, but if it's available in other colors and would be suitable, it might be fun to make some different colored eyeball fittings.</p>
