The present invention relates to a three-dimensional printing optimal size correcting device and a correcting method. The present invention provides a three-dimensional printing optimal size correcting device comprising: a modeling composition module for modeling a printing target three-dimensionally, thereby composing a modeling file; a three-dimensional printing module for printing the composed modeling file three-dimensionally, thereby fabricating a target sample; a deformation data measurement module for measuring data regarding deformation of the fabricated target sample and rendering the same into a numerical value; and a size correction module for calculating a size correction algorithm formula from the deformation data, which has been rendered into a numerical value, through regression model analysis, wherein the size correction module corrects the modeling file according to the calculated size correction algorithm formula, and the three-dimensional printing module three-dimensionally prints the corrected modeling file, thereby fabricating the final target sample. The present invention is advantageous in that coefficients of a two-dimensional regression curve are calculated from data regarding size deformation in X-axis, Y-axis, and Z-axis directions, resulting from arrangement inside a three-dimensional printing device, a size correction algorithm formula is applied therefrom, and a correction is made in the opposite direction of the predicted bending, thereby providing a better bending deformation phenomenon correction effect than the prior art. The present invention is also advantageous in that it is possible to improve deformation, which cannot be controlled by a scale factor adjusting method, for example, which is provided by a three-dimensional printer control program itself. |
