SUPPORT ARRANGEMENT DETERMINING APPARATUS, THREE-DIMENSIONAL PRINTING SYSTEM, AND METHOD of DETERMINING SUPPORT ARRANGEMENT

摘要

An arrangement determining apparatus includes a storing processor that stores data of a three-dimensional model of the target object, a reference processor that shifts and rotates the three-dimensional model, a center-of-gravity calculating processor that calculates a center of gravity of the three-dimensional model, a principal axis setting processor that calculates a farthest point that is most distant from the center of gravity of the three-dimensional model, and sets a principal axis connecting the center of gravity of the three-dimensional model and the farthest point, a tilting processor that tilts the three-dimensional model so that the principal axis is parallel or substantially parallel to a horizontal plane, and an arranging processor that attaches and arranges the supports on a top surface or a bottom surface of the three-dimensional model.

1. A support arrangement determining apparatus for determining a position arrangement of supports, for use with a three-dimensional printing apparatus wherein the supports are attached and arranged on a target object to be formed to form the target object and the supports, the arrangement determining apparatus comprising:
a storing processor configured or programmed to store data of a three-dimensional model of the target object; a reference processor configured or programmed to shift and rotate the three-dimensional model stored in the storing processor so as to set the three-dimensional model into a predetermined reference position and orientation; a center-of-gravity calculating processor configured or programmed to calculate a center of gravity of the three-dimensional model; a principal axis setting processor configured or programmed to calculate, among points on outer circumferential surfaces of the three-dimensional model, a farthest point that is most distant from the center of gravity of the three-dimensional model calculated by the center-of-gravity calculating processor, and set a principal axis connecting the center of gravity of the three-dimensional model and the farthest point; a tilting processor configured or programmed to tilt the three-dimensional model set in the predetermined reference position and orientation by the reference processor so that the principal axis set by the principal axis setting processor is parallel or substantially parallel to a horizontal plane; and an arranging processor configured or programmed to attach and arrange the supports on a top surface or a bottom surface of the three-dimensional model tilted by the tilting processor.
