I have been working on a ceramic tile design. I wanted to see if I could 3-D print a prototype in plastic and then make a plaster mold for production. I have learned it is pretty tricky to produce an interesting 3-dimensional image in such a shallow relief. I like this one, but I have to change the deep undercuts inside the sponges if I want to make a plaster mold that will ever come off. This design is a standard 6 x 6 inch tile size. I could just have the design printed in ceramics but the material cost alone would come in at about $200 per square foot (which is a little too crazy)…so I am still tinkering with it.
