A three-dimensional laminated mold is formed by ejecting a mold material into a groove formed in a support. The support is formed from a support material ejected from an inkjet head. The support material has a ratio of density difference of equal to or less than 13.5%. The ratio of density difference is calculated from an equation: n nratio of density difference=((D1-D2)/D1)×100 nwherein D1 indicates the density of the support material at 20° C., and D2 indicates the density of the support material at a temperature at which a viscosity of the support material measured using a rotational viscometer falls within the range of 10±1 mPa·s. |
