White nylon plastic with a matte finish and slight grainy feel.
About this Product
I tried a 1 mm/block version of Sentinel Castle, chopping off the western tower and turning off trees, as the walkway there looks too thin to print safely. Shapeways may decide to not try printing this one, but I thought it would be interesting to see. It's certainly much cheaper!
Update: sadly, Shapeways no longer will print this model, they've decided it's too risky to make and clean. I understand, as the sandstone material is pretty brittle and the cleaning process is laborious. So, it's off the market for the full color - if you order it, you're getting plastic. Someday we'll have a full color plastic printer and I'll offer it again...
