Hi there !
I just saw this topic. I work on these necrons proxy. Thanks to heavygear for talking about them !
I came here to help answer any question you could have and would love to know your opinion on them too !
The photos are indeed FUD models. I used a toothbrush and pure alcohol to quickly clean the models. I am not sure if it can be bought easily (I get this kind of product from my work) but I guess soap and hot water also work.
About the quality/pricing discussion, I agree that Shapeways products are too expensive and the FUD quality a bit lower than a good resin cast (though still pretty good), but I can't really afford better. I make these ships on my free time and Shapeways offer me an easy way to make them available to everyone.
My goal is to create close proxy for xenos fleets : there is a lot of imperium proxys available on the internet, but not many for the other armies, so I started with the necrons who have simpler geometrical shapes and could need some love.
About the battleship showed earlier by heavy, the model is nearly finished, but I can't afford a test order at the moment (I mainly need to check if it will be resistant enough despite its hollow hull). So no battleship until I can run my tests, sorry. :s
