Finally got round to painting up and basing my Shapeways Printed 15mm Russian KV2 Spider Tanks.
The prints are a weird thing in themselves they weigh hardly anything but are quite a sturdy, none-brittle material.
I use water based paints and they take to the printed surface (printed in detail not fuzzy prints) without issue.
The Shapeways 3D prints are expensive but you can get some really amazing models.
Just the decals, rusting and weathering left to do on these now...
