Title:
METHOD FOR MANUFACTURING THREE-DIMENSIONAL OBJECT AND INK SET FOR MANUFACTURING THREE-DIMENSIONAL OBJECT
Document Type and Number:
WIPO Patent Application WO/2024/004696
Kind Code:
A1
Abstract:
The present invention provides a method for manufacturing a three-dimensional object and an ink set for manufacturing a three-dimensional object, whereby it is possible to manufacture a three-dimensional object with good modeling accuracy, for example, even when manufacturing a complex-shaped three-dimensional object made of soft materials. The present invention pertains to a method for manufacturing a three-dimensional object, the method comprising the steps of: discharging (a) a modelling material ink containing a crosslinkable polymer and (b) a support material ink containing a support material, respectively; and removing an object from the support material ink after crosslinking the crosslinkable polymer, wherein either one of the modelling material ink (a) and the support material ink (b) further contains a hydrogen peroxide decomposer, the other further contains hydrogen peroxide or a hydrogen peroxide donor, and the discharged hydrogen peroxide decomposer decomposes discharged hydrogen peroxide and crosslinks the crosslinkable polymer, thereby creating a three-dimensional object.
