Title: LAMINATED MOLDING PRODUCTION METHOD AND LAMINATED MOLDING
Abstract:
This laminated molding production method comprises: a first step for preparing a copper alloy powder; a second step for producing a laminated molding using the copper alloy powder; and a third step for subjecting the laminated molding to heat treatment at a temperature of 300°C or higher. The copper alloy powder contains 0.10-1.00 mass% of chromium with the remainder being copper. The laminated molding is produced by sequentially repeating a step for forming a powder layer containing the copper alloy powder and a step for forming a molding layer by solidifying the copper alloy powder at a prescribed position in the powder layer, thereby laminating the molding layers.
