Metal shaped article production method

A metal shaped article production method for producing a metal shaped article based on shaping data, comprising:

• a shaping data input step of inputting the shaping data;
• a constituent material layer forming step of forming a constituent material layer using a constituent material containing metal particles constituting the metal shaped article and a thermoplastic resin;
• a support material layer forming step of forming a support material layer supporting the constituent material layer using a support material containing ceramic particles and a thermoplastic resin;
• a cut face cutting step of cutting a cut face in the constituent material layer of a stacked body formed by performing the constituent material layer forming step and the support material layer forming step;
• a degreasing step of degreasing the thermoplastic resin contained in the stacked body after performing the cut face cutting step;
• and
• a sintering step of sintering the metal particles by heating the stacked body, wherein
• in the support material layer forming step, the support material layer is formed so that a support face contacts with a face to be supported at an opposite side to the cut face at a position assumed to be deformed by cutting the constituent material layer based on the shaping data.
