Abstract
Provided is a three-dimensional object formation method for forming a three-dimensional object by at least repeating: forming a powder material layer using a powder material for three-dimensional object formation containing a base material coated with an organic material; and hardening a predetermined region of the powder material layer by delivering a hardening liquid to the powder material layer formed in the formation of a powder material layer, where the hardening liquid contains a cross-linking agent cross-linkable with the organic material.
