1. A three-dimensional object additive manufacturing method, wherein the method comprises:
forming a powder material layer by using a powder material;
applying a liquid material onto the powder material layer according to layer printing data, wherein the liquid material dissolves at least part of the powder material, and the liquid material comprises an active component capable of polymerization; and
supplying energy to the powder material layer so that the active component in the liquid material is polymerized, and the powder material itself is not polymerized and does not polymerize with the active component, and an area of the powder material layer to which the liquid material is applied is molded to obtain a slice layer of a three-dimensional object,
wherein the active component comprises a first active component, the first active component has an active group, and the first active component dissolves at least part of the powder material,
wherein the active component further comprises a second active component, the second active component has an active group, and the second active component does not dissolve the powder material,
wherein the second active component is filled into a gap between particles of the powder material or inside the particle of the powder material.
