The present invention refers to the process for the manufacture of hollow patterns of polymeric materials, produced by quick prototyped technologies, used in the manufacture of ceramic molds in the precision casting process. The invention refers to a process for the precision cast, which enables patterns totally different from those currently available on the market to be manufactured, these having an inner hollow design, which may be directly used in the manufacture of ceramic molds with the advantages of avoiding cracks and fractures in the same, also saving time during the process. |
