Shapeways has recently updated the Full Color Sandstone process, to be more reliable and give more consistent colors. I had some samples printed, to compare them with the old FCS, and to run some tests on them. Close up, detail pictures, as well as several destruction videos, are available in the thread on the Shapeways forums.

If you're interested in having things like this modeled for you for 3d printing to your design, feel free to contact me.
