I am working with a laboratory system that runs at a water pressure of ~40psi. We currently build the system using PVC parts, however there are no parts that fit the specifications we need, so we end up spending a lot of time hand-modifying the fittings.

I am curious how feasible it would be to print some of the fittings rather than modify existing PVC fittings. ABS and other plastics would also work for our application, so the material is not an issue. My primary question is if a 3D printed part could easily withstand 40psi? I would try to make the part as simple as possible to keep costs down, but don't want to start working on drawings before I get an idea of the relative strength of a printed part vs a molded part.

Any input appreciated!

Thanks,
Josh
