A copper alloy powder is a copper alloy powder for additive manufacturing. The copper alloy powder contains more than 1.00 mass % and not more than 2.80 mass % of chromium, and a balance of copper. A method for producing an additively-manufactured article includes a first step of preparing a copper alloy powder containing more than 1.00 mass % and not more than 2.80 mass % of chromium and a balance of copper and a second step of producing the additively-manufactured article from the copper alloy powder, and the additively-manufactured article is produced such that forming a powder layer including the copper alloy powder, and solidifying the copper alloy powder at a predetermined position in the powder layer to form a shaped layer are sequentially repeated to stack such shaped layers to thus produce the additively-manufactured article.

Copper alloy powder, method of producing additively-manufactured article, and additively-manufactured article

A metal powder for additive manufacturing includes: not less than 0.2 mass % and not more than 1.3 mass % of aluminum; and a balance including copper and an incidental impurity.

Metal powder, method of producing additively-manufactured article, and additively-manufactured article

A metal powder contains not less than 0.10 mass % and not more than 1.00 mass % of at least one of chromium and silicon, and a balance of copper. The total content of the chromium and the silicon is not more than 1.00 mass %. In accordance with an additive manufacturing method for this metal powder, an additively-manufactured article made from a copper alloy is provided. The additively-manufactured article has both an adequate mechanical strength and an adequate electrical conductivity.

A work holding mechanism for horizontally holding a flat work is incorporated in work transport equipment. The holding mechanism includes a base member for supporting the work and a plurality of guide members provided at the base member. Each guide member includes a shaft, a contact portion and a limit portion. The shaft is pivotally supported by the base member. The contact portion comes into contact with part of the lower surface of the perimeter of the work and is pushed down, with the shaft as a fulcrum, when the work is placed on the base member. The limit portion is raised, with the shaft as a fulcrum, to face part of the side surface of the perimeter of the work when the contact portion is lowered.
