3D printing material that is waterproof not brittle

Can anyone recommend a 3D printing material that is waterproof (doesn’t need painting) and is a little felxible (Not brittle)

ASA (UV resistant) but you need 4 or 5 shell layers.

Yes ASA is great, However cheaper ABS would do the trick also. Wraps more than ASA though so not as siutable for larger parts.

Thanks it’s for my cowel which I have already had printed in black pla but it’s very brittle

Carbon Filament is nice.
