Alu or Iron frame?

Iron seems like it would flex less than alu.

Thanks for your reply.

Its hard to tell, the iron is 3mm and the aluminum is 6mm. Personally, I'd probably go with the aluminum because of the way it looks. Also, not sure where you plan to used the printer, but iron will rust. If you're going to keep it in a damp basement or garage it'll rust pretty fast
