Hi Wayne,

I dont know how good the resolution on 3D printers is yet. Probably pretty good, but as good as the 1/100mm you can achieve on a CNC mill?
Will the media used in 3D printing warp depending on temperature differences when building or storing largish items like a foil?

16foot CNC router is doable. But the Z axis would be hard to make to allow the milling of whole hulls I think Perhaps if two half hull plugs were made.. hmmm..

Matt used to have some pics on the Vectorworks website from the milling of the Blade plugs. Large machine and a 2 step process with foam. I dont know if they faired or used putty on the plug but I believe the result is good enough from milling to just polish the part and then start moulding.
