At first I chose to design a hilly part with slopes in solidworks then saved it as a .stl file that I imported in Vcarve then I set it and chose a roughing choice to cut it then I cut it with the CNC machine shopbot and came out as perfectly as it could. With this stelloform to use epox on the sackcloth different natural fibers and resins. For one piece I used sackcloth and for the other one linen. Both of them are joined using a polyester matrix.
