Slice image creation device, three-dimensional printing system and slice image creation method

Abstract

In a slice image creation device, a peeling processor performs peeling on a peeling line segment in a circulation direction of the peeling line segment. When the peeling reaches an intersection at which line segments of contours cross each other, an intersection information acquisition processor acquires intersection information including an intersection angle defined at the intersection by the peeling line segment and each candidate line segment connected to the intersection in a direction that is the same as the circulation direction of the peeling line segment. A transfer processor sets one of the candidate line segments that has the smallest intersection angle as the line segment to which the peeling is going to be transferred next from the peeling line segment at the intersection. A creation processor sets the line segments on which the peeling has been performed continuously as one generated contour and divides a target slice model into a printing region and a non-printing region based on the generated contour to create a target slice image.
