Object producing method

An object producing method, comprising:

• forming a layer of a powder containing particles that are sinterable;
• applying an object forming liquid to the layer of the powder to form an object forming region;
• and
• applying a sintering inhibiting liquid to the layer of the powder to form a sintering inhibited region in which sintering of the particles is inhibited,
• wherein the object producing method further comprises sequentially repeating the forming, the applying the object forming liquid, and the applying the sintering inhibiting liquid, to form a laminate,
• the object forming region and the sintering inhibited region adjoin each other,
• the sintering inhibiting liquid contains a first resin,
• all compounds in the sintering inhibiting liquid are dissolved,
• the sintering inhibited region contains the first resin or a second resin derived from the first resin, and
• a predicted amount of a residue calculated by multiplying a mass ratio (mass of the first resin or the second resin/mass of the powder) between a mass of the first resin or the second resin and a mass of the powder in a sintering inhibited part formed by laminating the sintering inhibited region by a ratio of a residue of the first resin or the second resin through thermal decomposition at 550 degrees C. is 800 ppm or greater.
