Claim 0:
1. A three-dimensional molding method comprising the steps of:
molding a support material and a test piece supporting a part to be produced in the same step, based on dispersion of a powder by traveling of a squeegee on an upper side of a base plate and sintering of the powder by irradiation of a laser beam or an electron beam, the part to be produced having a sintered surface, the step of molding including the steps of:
molding the support material of the same material as the part to be produced and in a sintered strength which is weaker than a sintered strength of the part to be produced, and
molding the test piece of the same material as the part to be produced and in the same sintered strength as the part to be produced, such that the test piece is to be used for measurement of plastic deformation strength per unit volume of the part to be produced, and density of the part to be produced, and

carrying out the step of molding with both the support material and the test piece separately joined to partial regions of the part to be produced.
