Construction of product appearance online design system based on 3D printing technology
With the improvement of the precision and speed of 3D printing technology and the expansion of the selection range of 3D printing materials,3D printing technology is more and more widely used in medical,aerospace,fashion design,entertainment and other fields.During the construction of product appearance online design system based on 3d printing technology,aiming at the phe-nomenon of printing defects on the surface of 3d printing parts,a virtual and real matching defect detection algorithm suitable for the complex contour of three-dimensional model surface is proposed.The time consumption of the algorithm in the detection experiment is not more than 750ms,which can meet the real-time requirements of the online design system.The highest accuracy of 91.35%was obtained in the verification experiment of the detection accuracy of the algorithm,and it can effectively distinguish the own character-istics and real defects of the print model,which has practical application value for helping designers to conduct real-time online eval-uation and improvement of appearance design in the design system.
