Finished product model classification system on basis of 3D (three-dimensional) printing

Abstract

The invention discloses a finished product model classification system on the basis of 3D (three-dimensional) printing. The finished product model classification system comprises a three-view drawingacquisition module, a grayscale processing module, a similarity comparison module and a classification module. The three-view drawing acquisition module is used for acquiring three-view drawings of target finished product models; the grayscale processing module is used for carrying out grayscale processing on the three-view drawings of the target finished product models to obtain target grayscalethree-view drawings; the similarity comparison module is used for carrying out similarity comparison on the target grayscale three-view drawings and preset comparison grayscale three-view drawings toobtain target similarity values; the classification module is used for comparing the target similarity values to preset comparison thresholds and classifying the target finished product models corresponding to the target similarity values as qualified finished product models or to-be-modified finished product models or disqualified finished product models according to comparison results.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a finished product model classification system based on 3D printing. Background technique [0002] 3D printing (3D printing) is a kind of rapid prototyping technology. It is a technology based on digital model files and using bondable materials such as powdered metal or plastic to construct objects by layer-by-layer printing. An additive manufacturing technology, 3D printing has a variety of implementation technologies: such as FDM (fused deposition), SLS (laser selective sintering) and so on. [0003] At present, the 3D printers based on FDM technology on the market have strict temperature control in the printing area environment during printing. During batch printing, temperature control errors will cause deformation and warping of the printed finished model, and in serious cases will directly lead to printing. Failed, and there is currently no convenient method for the qu...
