A three-dimensional shaped article production method, which is a method for producing a three-dimensional shaped article by stacking layers, comprising: a layer formation step of forming each layer in a predetermined pattern by ejecting a composition (2', 5') containing particles using a dispenser (M2, M3); a measurement step of determining the height of the layer at a plurality of places; and a bonding step of subjecting a stacked body including a plurality of layers to a bonding treatment for bonding the particles, wherein at least some of the layers constituting the stacked body have a first portion corresponding to a portion to become an actual body part of the three-dimensional shaped article to be formed using an actual body part forming composition containing a first dispersion medium, first particles and a first binder, and a second portion corresponding to a portion to become a sacrificial part to be formed using a sacrificial part forming composition containing a second dispersion medium, second particles and a second binder, and in the case where when n represents an arbitrary integer of 1 or more, an n-th layer which is the layer in the n-th position has the second portion, and the second portion of an (n+1)th layer which is the layer in the (n+1)th position is formed on at least part of the surface of the second portion of the n-th layer, the supply amount of the sacrificial part forming composition per unit area to be ejected onto the second portion of the n-th layer from the dispenser in the layer formation step of forming the (n+1)th layer is adjusted based on the information of the height of the surface of the second portion of the n-th layer at the plurality of places so that the height of the n-th and (n+1)th layers together has a desired value. a layer formation step of forming each layer in a predetermined pattern by ejecting a composition (2', 5') containing particles using a dispenser (M2, M3); a measurement step of determining the height of the layer at a plurality of places; and a bonding step of subjecting a stacked body including a plurality of layers to a bonding treatment for bonding the particles, wherein at least some of the layers constituting the stacked body have a first portion corresponding to a portion to become an actual body part of the three-dimensional shaped article to be formed using an actual body part forming composition containing a first dispersion medium, first particles and a first binder, and a second portion corresponding to a portion to become a sacrificial part to be formed using a sacrificial part forming composition containing a second dispersion medium, second particles and a second binder, and in the case where when n represents an arbitrary integer of 1 or more, an n-th layer which is the layer in the n-th position has the second portion, and the second portion of an (n+1)th layer which is the layer in the (n+1)th position is formed on at least part of the surface of the second portion of the n-th layer, the supply amount of the sacrificial part forming composition per unit area to be ejected onto the second portion of the n-th layer from the dispenser in the layer formation step of forming the (n+1)th layer is adjusted based on the information of the height of the surface of the second portion of the n-th layer at the plurality of places so that the height of the n-th and (n+1)th layers together has a desired value.
