Abstract:
The invention is directed to a process of manufacturing a three-dimensional object by depositing and solidifying molten polyvinyl alcohol (PVOH) to form a support structure depositing and solidifying a molten thermoplastic polymer on the support structure to form a three-dimensional preform dissolving the support structure to from the three-dimensional object characterized in that the polyvinyl alcohol (PVOH) has an alkaline acetate content of less than 0.5 wght%.
