There is provided a three-dimensional laminating and shaping apparatus having the following arrangement. That is, the three-dimensional laminating and shaping apparatus includes a material ejector that ejects a material of a three-dimensional laminated and shaped object onto a work on which the three-dimensional laminated and shaped object is shaped. The three-dimensional laminating and shaping apparatus includes a light beam irradiator that irradiates the ejected material with a light beam. Furthermore, the three-dimensional laminating and shaping apparatus includes a jig to which the work is detachably attached. The jig includes a channel supplied with a cooling medium for cooling the work. ## Claims ### Claim 1 A three-dimensional laminating and shaping apparatus comprising: a material ejector that ejects a material of a three-dimensional laminated and shaped object onto a work on which the three-dimensional laminated and shaped object is shaped; a light beam irradiator that irradiates the ejected material with a light beam; and a jig to which the work is detachably attached and that includes a channel supplied with a cooling medium for cooling the work, wherein the channel is formed on a contact surface side where said jig is in contact with the work, and is open to the contact surface side so that the cooling medium contacts the work, and is formed in a concentric shape with respect to a center of said jig. ### Claim 2 (depends on 1) The three-dimensional laminating and shaping apparatus according to claim 1, wherein the channel has a groove shape open to the contact surface side. ### Claim 3 (depends on 1) The three-dimensional laminating and shaping apparatus according to claim 1, wherein the channel has two flow inlets and one flow outlet. ### Claim 4 A control method of a three-dimensional laminating and shaping apparatus, comprising: ejecting a material of a three-dimensional laminated and shaped object onto a work on which the three-dimensional laminated and shaped object is shaped; irradiating the ejected material with a light beam; and supplying a cooling medium for cooling the work to a jig to which the work is detachably attached and that includes a channel supplied with the cooling medium, wherein the channel is formed on a contact surface side where said jig is in contact with the work, and is open to the contact surface side so that the cooling medium contacts the work, and is formed in a concentric shape with respect to a center of said jig. ### Claim 5 (depends on 4) The control method according to claim 4, wherein the cooling medium is supplied to said jig when a temperature of the work exceeds a given threshold.
