Could this foretell a solution to the recent dearth of O Scale brass imports?
Hopefully it will. I can see a lot of new models being produced out of resin, until the printable metal resins are becoming more affordable.
The transition should not be too difficult as most modern brass models currently produced are already designed in 3D CADCAM format. It should also allows a more friendly and less polluting process of fabrication, moving away from lost wax and high temperatures molding.
