Document Type and Number:
WIPO Patent Application WO/2024/063002
Kind Code:
A1
Abstract:
The present invention provides: a method for manufacturing a three-dimensional additively manufactured object, whereby it becomes possible to achieve a satisfactory working environment and it also becomes possible to readily manufacture a three-dimensional additively manufactured object having a practically useful level of strength; and a three-dimensional additive manufacturing kit. The method for manufacturing a three-dimensional additively manufactured object comprises a step (a) for spreading a fire-resistant granular material in layers and a step (b) for injecting a binder over a desired region in the fire-resistant granular material that has been spread in layers, in which the binder comprises a saccharide and a polyhydric carboxylic acid, and the steps (a) and (b) are repeated until a desired three-dimensional additively manufactured object is manufactured. The three-dimensional additive manufacturing kit comprises a fire-resistant granular material and a binder separately, in which the binder comprises a saccharide and a polyhydric carboxylic acid.
