For those you you who use i.materialise as a 3D printing service, you will be glad to see that they have just announced a new type of material. The material is Multicolor gloss sandstone. Basically it is the same as their normal sandstone material, but they add a thicker coating of UV resin on top of the print. This gives objects a lightly polished stone like look and feel to them. The prices are the same as the normal matte sandstone material. More details can be found here: http://3dprint.com/13418/sandstone-multicolor-gloss/

Below is an example of the matte finish next to the gloss finish. What do you think?
