METHOD FOR MANUFACTURING HYBRID SHAPED ARTICLE, AND HYBRID SHAPED ARTICLE

WIPO Patent Application WO/2017/195773

A1

[Problem] To improve productivity of three-dimensional shaped articles made by a powder sintering and layering method. [Solution] The present invention comprises: (1) a first step for detachably mounting a first shaped article 2 onto a base plate 6; (2) a second step for mounting the base plate 6, on which the first shaped article 2 has been detachably mounted, onto a vertically-moving table 5 of a powder sintering and layering device 4; (3) a third step for repeatedly performing work for forming, on the first shaped article 2, a powder layer 12 that can be bonded to the first shaped article 2, and work for irradiating the powder layer 12 with laser light to form a solid layer 15, to integrally form, on the first shaped article 2, a second shaped article 3 serving as a three-dimensional shaped article on which a plurality of solid layers 15 have been layered and integrated together, thus forming a hybrid shaped article 1 composed of the first shaped article 2 and the second shaped article 3; (4) a fourth step for taking the hybrid shaped article 1 and base plate 6 out from the vertically-moving table 5 of the powder sintering and layering device 4; and (5) a fifth step for taking the hybrid shaped article 1 out from the base plate 6.
