Claim 0:
1. A three-dimensional shaped article production method for producing a three-dimensional shaped article by ejecting a shaping material to a stage and stacking layers according to a path including multiple partial paths, comprising: a first step of specifying a gap portion occurring inside the three-dimensional shaped article based on first shaping data having data for shaping a first portion that is a part of the three-dimensional shaped article by stacking a plurality of layers each having a first thickness, and data for shaping a second portion that is a part of the three-dimensional shaped article and is adjacent to the first portion in a direction orthogonal to a stacking direction of the layers, the second portion being a single layer having a second thickness corresponding to a total thickness of the first portion; a second step of generating second shaping data from the first shaping data by changing the first shaping data so as to fill up the gap portion when the gap portion is specified;
wherein in the second step, the second shaping data are generated by generating data for shaping while increasing the line width in the partial path adjacent to the gap portion;
wherein in the second step, when a first partial path and a second partial path are adjacent to the gap portion, the second shaping data are generated by generating data for shaping while increasing the line width in the second partial path, and then,
generating data for shaping while increasing the line width in the first partial path adjacent to the gap portion that is shrunk after the line width of the second partial path is increased, the second partial path being located closer to a center of the three-dimensional shaped article than the first partial path;
and a third step of shaping the three-dimensional shaped article by ejecting the shaping material according to the second shaping data.
