SOLID SHAPING METHOD
Document Type and Number:
WIPO Patent Application WO/2022/209028
Kind Code:
A1
Abstract:
Provided is a solid shaping method that can prevent a shell material from being drawn into a core material with which filling has been performed. This solid shaping method shapes a solid shaped product by first using a shell material to shape a shell layer, which is an outer shell layer of the solid shaped product, and then using a nozzle member to eject a core material and fill a core section with the same, said core section being a section that is surrounded by the shaped shell layer. The shell layer is shaped by curing a portion of the shell material which is in a fluid state, at least a tip end of the nozzle member is inserted into the uncured shell material that remains in the core section, and the core material is ejected from the tip end of the nozzle member, thereby exchanging the uncured shell material and the core material and filling the core section with the core material. This solid shaping method is configured such that the core section is filled with the core material while maintaining a state in which the core material has an interface only with the uncured shell material.
