Kraftwurx is an ideal source for casting waxes. Recently I worked with a jewelry designer to create some custom pieces. We needed maximum detail possibly as these pieces were very small. He was able to quickly upload his 3d models and order waxes of them from Kraftwurx.com in the "Nano Wax Blue" material, which is CPX200 Wax. The wax 3d prints turned out spectacular. He was very impressed wit the speed of the service and quality of the prints. I've attached some images of the wax 3d prints we got.
