an interesting site to check the properties of several types of plastics can be found here
Hey @Walter what do you think of this 1 as a replacement for aluminum castings on my sailboat? Taulman 910 Nylon
Nylon is wear resistant and behaves well under load. Depends what the use will be...
rudder castings for a catamaran...
Taulman 910 is a very durable material. I would print it solid and slow and see how it goes. I do not know of any mainstream plastics that would be better suited for that application. The only thing I would worry about would be UV damage.
