What has been people's experience with castings from Shapeways made with white nylon plastic? The tender casting I bought is excellent; however, I found the material very difficult to work with. It neither sands well nor can it be filed easily. It is very tough to cut with a modeling knife although a razor saw works well. I also found that epox or cyanopoxy glues provide the best bond to the material. I have read that acrylic paints must be used since enamels dissolve the nylon plastic. I'd appreciate learning of anyone's experiences with these models.
