Innovation in the designing process and its strategic implementation opens diverse possibilities. This concept in the jewelry and artifacts can reap enormous benefits when used with additive manufacturing (AM) technologies. AM has established its proficiency in various manufacturing sectors, medical fields, and art as it offers freedom, customization, and quick changes in design. This study investigates the use of additive manufacturing in jewelry modeling, jewelry design, and manufacturing. Additionally, modeling of ornaments has been carried out by using Rhinoceros software. We also provide a brief overview of the use of smart jewelry. These days, smart medical alert devices like smart watches could be developed as an ornamental and health device. These are used to check various health conditions like temperature, heart rate, calorie burn data, and sleep cycle. Furthermore, with AM, they can be customized and manufactured based on the individual customer's requirement. Similarly, for other ornamental devices, this will open a new field with enormous scope.

“…Due to the fuzzy matching, a lot of noise will be present in the obtained point cloud. The latter, including laser scanners [ 7 ], structured light scanners [ 8 ] and lidar [ 9 ], can quickly obtain complete point clouds. However, due to the uncertainties of measurement errors, reflectance from objects, occlusion, illumination and the environment, the obtained point cloud data of objects often contain a large number of complex noise points [ 10 ].…”

A point cloud obtained by stereo matching algorithm or three-dimensional (3D) scanner generally contains much complex noise, which will affect the accuracy of subsequent surface reconstruction or visualization processing. To eliminate the complex noise, a new regularization algorithm for denoising was proposed. In view of the fact that 3D point clouds have low-dimensional structures, a statistical low-dimensional manifold (SLDM) model was established. By regularizing its dimensions, the denoising problem of the point cloud was expressed as an optimization problem based on the geometric constraints of the regularization term of the manifold. A low-dimensional smooth manifold model was constructed by discrete sampling, and solved by means of a statistical method and an alternating iterative method. The performance of the denoising algorithm was quantitatively evaluated from three aspects, i.e., the signal-to-noise ratio (SNR), mean square error (MSE) and structural similarity (SSIM). Analysis and comparison of performance showed that compared with the algebraic point-set surface (APSS), non-local denoising (NLD) and feature graph learning (FGL) algorithms, the mean SNR of the point cloud denoised using the proposed method increased by 1.22 DB, 1.81 DB and 1.20 DB, respectively, its mean MSE decreased by 0.096, 0.086 and 0.076, respectively, and its mean SSIM decreased by 0.023, 0.022 and 0.020, respectively, which shows that the proposed method is more effective in eliminating Gaussian noise and Laplace noise in common point clouds. The application cases showed that the proposed algorithm can retain the geometric feature information of point clouds while eliminating complex noise.

“…The obtained 3D model can be used to reproduce the technical documentation, perform a strength analysis or determine the quality of the manufactured product without destructive methods. The development of this technology has made it popular in areas such as automotive industry [8][9][10], medicine [11], archaeology [12], arts [13], cultural heritage reconstruction [14], casting [15] and forging [16]. The paper [8] presents studies concerning the application of the 3D scanning technology to sheet-metal parts and sets of automotive dies.…”

“…It is an indispensable part of the reverse engineering (RE) process that allows one to obtain a CAD model in the case of lack of proper technical documentation [ 7 , 8 ]. The main objective of the 3D scanning process is the most accurate representation of a real object in a digital form [ 9 ]. The 3D scanning technology uses an intense light source with a detector which cooperates with the software to recreate the scanned object [ 10 ].…”

Bells as percussion instruments have been known to humanity for ages. The casting process, the shape and the materials have changed over the years. The functional properties of bells depend on the casting quality and the generated sound. The casting quality is related to the shape, material and technology. The acoustic quality must fulfill specific parameters. This work concerns the assessment of the quality of the manufactured bells and the possibility of replacing tin bronze with a material with similar mechanical properties. Therefore, bell bronze—which is dedicated to this type of work—and aluminum bronze—which is characterized by high strength and hardness, have been applied to casting. The laser scanning technique was used to assess the quality of castings. Based on a point cloud, an optimized mesh was generated from which the 3D model was finally created. On the basis of the CAD model, the defects resulting from the casting process were determined in the form of graphical comparison. The correctness of the selected foundry shrinkage of the selected material was also determined. The manufactured bells were also assessed for sound quality. Vibration frequencies were determined using a vibration analyzer and free software Wavanal. The experimental results were compared with the ones obtained from the numerical frequency analysis. With the help of tests, the quality of the bells was assessed, and it was determined whether aluminum bronze meets the acoustic criteria. The presented method can be used in the development of bell templates. These templates will allow the bell to obtain the correct shape and acoustic quality without the need for a tuning process.
