“…Printing problems may also arise in models with high level of detail on a small surface part (see e.g. filigree jewelry [19]) due to AM technology limitations. Another type of "poor printability" is encountered when many support structures must be included to facilitate printing.…”

Additive manufacturing technologies are positioned to provide an unprecedented innovative transformation in how products are designed and manufactured. Due to differences in the technical specifications of AM technologies, the final fabricated parts can vary significantly from the original CAD models, therefore raising issues regarding accuracy, surface finish, robustness, mechanical properties, functional and geometrical constraints. Various researchers have studied the correlation between AM technologies and design rules. In this work we propose a novel approach to assessing the capability of a 3D model to be printed successfully (a.k.a printability) on a specific AM machine. This is utilized by taking into consideration the model mesh complexity and certain part characteristics. A printability score is derived for a model in reference to a specific 3D printing technology, expressing the probability of obtaining a robust and accurate end result for 3D printing on a specific AM machine. The printability score can be used either to determine which 3D technology is more suitable for manufacturing a specific model or as a guide to redesign the model to ensure printability. We verify this framework by conducting 3D printing experiments for benchmark models which are printed on three AM machines employing different technologies: Fused Deposition Modeling (FDM), Binder Jetting (3DP), and Material Jetting (Polyjet).

This manuscript reports a geometrical and a topological methods to segment a closed triangular 2-manifold mesh M ⊂ R 3. The mesh M does not self-intersect) and has no border (i.e. watertight. Geometrical and topological segmentation methods require a Boundary Representation (BRep) from M. Building the BRep for M uniforms the triangle orientations, and makes explicit triangle and edge-counter edge adjacency. In the context of Reverse Engineering, the sub-meshes produced by the segmentation are subsequently used to fit parametric surfaces, which are in turn trimmed by the sub-mesh boundaries (forming FACEs). A Full Parametric Boundary Representation requires a seamless set of FACEs, to build watertight SHELLs. The fitting of parametric surfaces to the triangular sub-meshes (i.e. sub-mesh parameterization) requires quasi-developable sub-meshes.

“…In the last decades, an always growing approach towards the innovation in design has been adopted in the use of digital technologies, applied both in terms of computer software and prototyping [7][8][9][10][11][12][13]. Editable computer-aided drafting (CAD) representations, accurately capturing the original design and allowing re-parameterization and modification prior to manufacturing, have been developed and studied [14]. Semantic feature modeling systems for sketch-based jewelry design were also proposed [15].…”

This paper reports the results of the designing, manufacturing and characterization of a jewel obtained by means of coupling the dogmas of industrial design to the analytical engineering approach. The key role in the design of the jewel was played by an in-house synthesized Neodymium (Nd)-doped phosphate glass, selected due to its easy handling and capability to change color according to the incident light wavelength. The glass core was covered by a metal alloy to mitigate its relatively high fragility and sensitivity to thermal shock and, at the same time, to highlight and preserve its beauty. The selection of the proper metal alloy, having thermo-mechanical properties compatible with those exhibited by the glass, was carried out by means of Ashby’s maps, a powerful tool commonly adopted in the field of industrial design.
