Abstract
An infill apparatus and method for an output of a 3D printer, including a unit block generating part which slices a 3D model by using three planes orthogonal to each other to generate unit blocks; a unit block classifying part which classifies the unit blocks into boundary unit blocks and internal unit blocks according to positions thereof and classifies the boundary unit blocks into flat roof unit blocks and non-flat roof unit blocks according to whether or not a flat roof region is included; a combined block generating part which merges the internal unit blocks and generates a combined block; a flat roof point discriminating part which discriminates flat roof points in the combined block; a combined block dividing part which divides a part of the combined block including the flat roof points; and an infill shape determining part which determines a divided surface (or contact surface) of the combined block divided by the combined block dividing part as infill shape and outputs a printing material to the infill shape during outputting.
