This is L4023F (a test body like our H440 cone 10R body). I did not sand or alter the surface on the 3D printed block mold or on the plaster case mold I cast from it. The polygons are produced when the 3D CAD software converts from its native format to an STL file that slicer software can use. These are not visible in the final glazed piece either.
The actual mold (top left) vs 3D drawn one (lower). The case mold (top right) separated from the 3D print easily. The join between top and bottom sections of the 3D print is invisible. An advantage of making plaster case molds, vs flexible rubber, is the extra opportunity to smooth surfaces and fix defects (this case mold has some small surface defects at the top of the handle, these will be easy to remove from working molds). The rigidity of the plaster case mold enables the use of 3D printed rails having a flange that goes under the edge all the way around, this reduces issues with potential plaster leakage.
