Claim 5:
6. A three-dimensional molding method comprising the steps of:
molding a part to be produced and a test piece supporting the 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 and the test piece being connected between the part to be produced and the base plate,
wherein the entire test piece extending between the part to be produced and the base plate is made of the same material as the part to be produced and in a same sintered strength as the part to be produced without employing any support material having a sintered strength which is weaker than a sintered strength of the part to be produced, and 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 the test piece being joined to partial regions of the part to be produced by at least one unit.
