The Integration and Design of Green Concept in Jewelry under the Background of Information Technology

This paper first integrates the green concept into jewelry design from three aspects of jewelry materials, modeling and production process, and demonstrates the jewelry 3D printing technology in line with the green concept in the context of information technology and analyzes its technical process. Then, based on the PCA method and the point cloud data of space lattice, the three-dimensional normal estimation of jewelry is carried out, the three-dimensional reconstruction and cavity repair of jewelry is carried out through the triangular mesh model, and the complete output of the jewelry model in STL format is carried out, and the STL fast slicing is carried out. Finally, the effects of 3D modeling, slicing efficiency, and jewelry design are analyzed through numerical simulation experiments. The results show that the standard deviation of the error in the x-direction σ =0.16um, expectation μ =−0.007um, the standard deviation of the error in the y-direction σ =0.08um, expectation μ =0.003um, and the standard deviation of the error in the z-direction σ =0.28um, expectation μ =−0.001um, with a variation range of (−0.028, 0.028), in the three-dimensional modeling of jewelry. Compared with the traditional slicing algorithm, this paper’s slicing efficiency of jewelry is improved by (0.26, 0.45), when the production quantity is more than 500 pieces, in terms of the cost of the traditional production method is more advantageous.
