Abstract
A three-dimensional object molding method and molding device, where the method includes the following steps: forming a powder particle layer, wherein the powder particle layer at least contains thermosetting powder particles capable of undergoing thermal polymerization; spraying a photocurable material onto the powder particle layer according to layer printing data, such that the photocurable material covers at least part of the powder particle layer and permeates into this layer; curing the photocurable material to form a slice layer; repeating the steps to obtain a plurality of slice layers, and stacking the plurality of slice layers layer-by-layer to form a three-dimensional object green body; and heating the green body to thermally polymerize the thermosetting powder particles so as to obtain the three-dimensional object. The method provided in the present application enables the obtained three-dimensional object to have very good mechanical properties and a high molding accuracy.
