I have done a couple of attempts with a mold i created with the uni-mold. The mold was not post cured. When i make parts that is not post cured there is no problem, but when I create parts that i post cure i get a carbon fiber pattern in the mold surface. This pattern I have to sand down with 1200 paper to get it flat after I demold the part.
Is this happening because I did not post cure the mold? Do I have to make a new mold?
