Abstract:
The purpose of the present invention is to optimally remove unnecessary powder from a metal lamination-shaped article. This cleaning device (10) is for cleaning a metal lamination-shaped article (20) formed by laminating layers which are each obtained by layering a metallic powder material and irradiating a portion thereof with a laser beam to melt-bond or sinter the same. The cleaning device (10) comprises: an inner container (12) that is filled with a mixed solvent M being a liquid obtained by mixing a plurality of organic solvents and that accommodates the metal lamination-shaped article (20) in a state of being immersed in the mixed solvent M; and an ultrasound-emitting device (13) which transmits ultrasounds (U) to the metal lamination-shaped article (20) being accommodated in the inner container (12). The plurality of organic solvents include: a first organic solvent that has a higher vapor pressure than the other organic solvents; and a second organic solvent that has a higher acoustic impedance than the other organic solvents.
