Ideas how/where to replicate large plastic parts?
(OP)
Does anyone know where I can get a fan replicated like this black one in the picture below? It has to be durable, lightweight, and 1.5ft - 2ft in diameter. Preferably plastic that can withstand large amount of force.

I'm building a blower/vacuum out of a 10hp motor. I could have someone fabricate one out of aluminum but it would be too wobbly and heavy. I couldn't think of a way or place that will replicate something in plastic. Anybody point me in the right direction would be greatly appreciated.
Many thanks in advance.

What's the application? Will it run at a constant speed or cycle up and down? What kind of temperatures will it see? Any chemicals in the air?
Not sure what you mean by aluminum being too woblly. If it is balanced, it doesnt matter what material it is: if it isn't balanced, it still doesnt matter. Aluminum is approximately three times denser than an unfilled plastic, but about 10 times stronger, depending on the grades chosen. If you go to a fiber reinforced plastic, those ratios change a bit. The point is that if you design it correctly, the aluminum will not necessarily be heavier.
