“…The influence of the printing parameters of EBM technology [6][7][8] on the mechanical performance of the components had been evaluated through tension tests, which were performed on specimens of fixed dimensions by varying only one printing parameter (material growth direction) among the most influential ones. The specimens were made according to the classic geometry for tension tests, called "dog bone," with a useful length of 40 mm and a circular section with a nominal diameter of 2 mm.…”

“…The phases of the transformation cycle are identical for all additive technologies, what distinguishes them is the way in which the individual layers are generated and the physical principle with which the adjacent layers of material are attached and connected to each other. Unlike conventional processes, [2][3][4][5] the material characteristics of a part produced by addition are therefore determined both by the properties of the raw material and by the process parameters of the technology used to print the part. For this reason, the final properties of the component are the result of both the process and the composition of the base material.…”

The aim of this study is to investigate the mechanical properties of the specimens made of Ti6Al4V titanium alloy with EBM additive technology. Tensile tests on the component are carried out on “dog bone” specimens, of fixed dimensions, printed with orientations of 0°, 45°, and 90°. The results of the experimental campaign confirm the influence printing parameters of the technology on the mechanical performance of the components. Subsequently, the numerical‐structural analysis carried out on the Octet‐Truss elementary cell in Ti6Al4V titanium alloy shows that the mechanical behavior of the cell is influenced by the material growth orientation and confirmed that the orientation of 45° guarantees cells more resistant to loads of traction, while the orientations of 0° and 90° make up more deformable cells. The investigation of the mechanical properties of the components involved specimens with a solid material configuration and specimens is emptied by means of reticular structures. The results of the survey are compared with the same volume and with the same analysis. Direct observation of the stress–strain curves reveals a difference in the value of the elastic modulus, resulting in a linear section of the curve that is less steep in the case of the assembled component. The choice of the printing parameters is a crucial point in the construction process of the components made in Additive Manufacturing since, as confirmed by this study, the parameters of the technology influence the properties of the material and therefore of the printed component. Secondly, exploiting the potential of additive technologies in creating structures with complex geometry (such as lattice structures), offers the possibility, not only to reduce the weight of the components, but also to improve the final performance.

“…Likewise, considerable papers present generic methods (16 papers) in addition to specific methods (10 papers) to support development of industry 4.0 solutions. These methods involve technologies such as augmented reality [35] virtual reality [36], digital twins [37], cloud-based platforms [38], while some of these methods support specific design aspects such as integrability between product design and manufacturing [39], design of product quality monitoring systems [40], intelligent product design with CPS feedback [41], CPS user interface design [42], IoT-based systems [43]. 15 papers were assigned to 'other' category, which involved methods featuring simulations, automated/smart/generative design, knowledge feedback, product lifecycle management (PLM) and manufacturing execution system (MES) tool-based approaches as well as review papers.…”

Since its introduction in 2011, industry 4.0 has been coined the "4th industrial revolution" following mechanization, industrialization and IT/automation as the first three, and represents the current trend of automation technologies (cyber-physical systems, internet of things, cloud computing, etc.,) in the manufacturing industry, with their potential for disruption of the manufacturing paradigm as we know it. However, the effect and role of industry 4.0 on the design and development of the new products to be manufactured in industry 4.0 facilities is not clear. This research presents a literature review to; 1) understand the concept of industry 4.0 from an implementation (state of practice) viewpoint, 2) learn about approaches and considerations currently deployed for developing products to be produced in manufacturing plants progressively transforming into industry 4.0 environments. Results reveal that the potential of industry 4.0 is underexploited within product design and development, especially in the conceptual stages lacking methods, tools, and approaches. While later stages of the product development (production planning, ramp-up) have received some attention in regards with optimizing production operations, several publications acknowledge its potential to benefit earlier process stages.

“…Industrial world has been greatly influenced by I4.0 and it is currently facing great changes due to the innovation led by new technologies and new sustainability principles. [1] I4.0 is revolutionizing both small-medium enterprises and great industries by introducing new approaches for cost optimization, also in innovative fields, such as the Additive Manufacturing, [2] moreover, factories are becoming "smart," [3] by integrating product and process design [4] in order to improve productivity. In this context, some technologies, which have been considered very expensive until few years ago, are becoming cheaper and accessible to small enterprises.…”

The advent of Industry 4.0 (I4.0) principles and technologies has been a great boost for manufacturing companies, constantly focused on the production processes optimization in order to reach the double objective of improving productivity and minimizing related costs. Today, the use of I4.0 technologies seems to be more accessible for a large number of companies, allowing to perform a more detailed analysis on their processes by means of experimental data coming directly from the system. In this context, ergonomics, which has been underestimated until 30 years ago, is assuming more and more importance. This paper aims at proposing a methodology focused on an ergonomic analysis carried out by implementing data collected from the field; in particular, a set of inertial sensors integrated in the worker suit detects the body posture. Then, thanks to the Industrial Internet of Things (IIoT), data are transferred to a simulation software in order to quickly evaluate the current ergonomic effort. In this way, it is possible to perform a real-time evaluation on the workstation design and consider a possible re-design with the aim of improving ergonomics.
