[Problem] Provided is a three-dimensional molding method wherein in three-dimensional molding of a part to be produced, support material and test piece, the test piece either supports the part to be produced, or is joined with the support material supporting the part to be produced, thereby allowing efficient molding and efficient utilization of the powder, and three-dimensional molded articles obtained by the method are also provided.
[Solution Means] The object is achieved by a three-dimensional molding method in which both a support material (2) and a test piece (3) are separately joined to partial regions of a part to be produced (1), which is molded by dispersion of a powder by traveling of a squeegee and sintering of the powder by irradiation of a laser beam or an electron beam, or the test piece (3) is separately joined to a plurality of the support materials (2), or the test piece (3) is joined to a partial region of the part to be produced (1) to mold the support material (2) and the test pieces (3) in the same step.
