The next level in design

Ok so here I'm think how i could step up to the next level in desgin in both detail and articulation.

The answer is 3D printing.

The upside:
The results would be highly detailed, prefect articulation, hollow light weight parts.

The downside:
Cost for 3D drawing, Cost for 3D printing. My guess its £600 or more just for the prototype before casting costs.

The net result;
You get an exceptional professional quality model to play with, but its likely to cost £100+ not matter if its a light or an assault..

Its a big risk for me to take if the math doesn't stack up for me or yourselves. Your thoughts in the comments or on email;
