3D printed nylon moulds for an RTV silicone part

Sorry if this has been answered elsewhere (I tried searching!) but does anyone have any experience using 3D printed nylon as a mould for an RTV silicone part?

Specifically, my question is - would the nylon act as an inhibitor for addition cure RTV silicone (like this stuff)?  The specific type of nylon is PA2200, which looks like it's basically PA 12. 

I can't think of a reason why that nylon would cause problems, since it's not on the list of inhibitors, but I thought I'd check first!

Thanks in advance.

These cheap 3d printers do seem to be revolutionising budget rapid prototyping.

I want a cheap 3d scanner and cheap way of CAD machining moulds from tooling boards.
