Three-dimensional shaping method

A three-dimensional shaping method for shaping a three-dimensional shaped object using a three-dimensional shaping device comprising:

• a shaping table having an upper surface with a surface roughness on which the three-dimensional shaped object is shaped;
• an ejection unit;
• a planar scanning driving unit;
• and a flattening unit, wherein three-dimensional shaping method comprises:
• utilizing the ejection unit to eject ink for three-dimensional shaping;
• utilizing the planar scanning driving unit to relatively move the ejection unit with respect to the shaping table in a plane parallel to the upper surface of the shaping table;
• utilizing the layering scanning driving unit to relatively separate the ejection unit and the shaping table from each other in a layering scanning direction which is a direction perpendicularly intersecting the planar direction and in which the ink is layered;
• utilizing the flattening unit to flatten the ejected and layered ink;
• and
• layering a plurality of layers on the shaping table before shaping the three-dimensional shaped object to form a support layer disposed between the shaping table and the three-dimensional shaped object to support the three-dimensional shaped object from a lower side and compensate the surface roughness to obtain the upper surface in a flat shape;
• wherein
• the plurality of layers have a lower part side in a vertical direction of the plurality of layers formed only by the planar scanning driving unit, and an upper part side in the vertical direction of the plurality of layers formed using both the planar scanning driving unit and the layering scanning driving unit.
