METHOD FOR MANUFACTURING THREE-DIMENSIONAL MOLDED OBJECT
PROBLEM TO BE SOLVED: To provide a method for manufacturing a three-dimensional molded object for reducing a load upon separating a three-dimensional molded object from above a support.SOLUTION: The method for manufacturing a three-dimensional molded object aims to manufacture a three-dimensional molded object by stacking layers to form a laminate, and the method includes: a first layer forming step 7A of supplying a first composition comprising first particles and a binder to form a first layer S1 on a support 121; a second layer forming step 7B of supplying a second composition comprising second particles and a binder to form a second layer S2 made of a single layer or a plurality of layers on the first layer S1; and a separation step 7E of separating the second layer S2 from the support 121 via the first layer S1. The method further includes, after the separation step, a sintering step 7F of sintering the second layer S2.SELECTED DRAWING: Figure 7
