Si mette a fuoco lo stato dell'arte dell'uso del laser scanner e del 3D Modeling per il rilevamento dei beni culturali individuandone le criticità. L'impatto estetico degli elaborati digitali sembra infatti talora prevalere su un'incisività del rilievo inteso come strumento critico, a favore di una clonazione superficialmente conoscitiva di quei dati più immediatamente riconducibili alla categoria del visivo.

In disseminating and promoting the understanding of the cultural heritage, 3D modeling is increasingly used to provide an idea of what objects actually

Today, new computer techniques are increasingly employed in archaeology. Such techniques, organised according to a proper
pipeline, allow a fuller knowledge of archaeological assets. In the study of the Nympheum Colonna at Genazzano, attributed to
Bramante, an integrated approach to technologies like photogrammetric survey, 3D modelling, virtual tour and 3D printing, enables
a scale reproduction of the image of the Nymphaeum at the beginning of the 16th century. First, data are acquired through

The exploitation of mechanical properties and customization possibilities of 3D printed metal parts usually come at the cost of complex and expensive equipment. To address this issue, hybrid metal/polymer composite filaments have been studied allowing the printing of metal parts by using the standard Fused Filament Fabrication (FFF) approach. The resulting hybrid metal/polymer part, the so called “green”, can then be transformed into a dense metal part using debinding and sintering cycles.

ABSTRACTBackground:Surgery and technological innovation have begun to move at the speed of light, with innovations and discoveries such as virtual reality, robotic systems, navigation surgery, and 5G networks radically revolutionizing the surgical world as well as the medical world in general, bringing significant benefits for healthcare professionals and patients alike. Technology will increasingly be a crucial element in surgical and medical development. This new therapeutic approach aims to enhance human–computer interaction by putting a new “patient” figure at its center.

In recent years, three-dimensional reconstruction (3DR) models have become a standard tool in several medical fields such as education, surgical training simulation, patient–doctor communication, and surgical planning. Postoncologic reconstructive surgery in thoracic diseases might benefit from 3DR models; however, limited data on this application have been published worldwide. In this paper, the aim was to report our experience with 3DR modeling to determine resection and plan the surgical reconstruction in a patient with a desmoid tumor of the chest wall.

Tailoring the morphology of macroporous structures remains one of the biggest challengesin material synthesis. Here, we present an innovative approach to fabricatecustommacroporous materials with pore size varying throughout the structure by up to an order of magnitudeusingon-demand reconfigurable microfluidics. We employavalve-based flow-focusing junction(vFF)in which the size of the orifice can be adjusted in real-time (within tens of milliseconds)to generate foams withon-linecontrolled bubble size.

In additive manufacturing (3D printing) processes, polyethylene (PE) filaments can be taken into consideration build and recycle components in space, thus reducing costs, risks, and logistics issues that can occur during a long-term mission beyond Low Earth Orbits. In fact, the excellent radiation shielding properties of polyethylene, which are due to its high content of hydrogen, have found consensus among the scientific community. On the other hand, PE shows poor mechanical, electrical, and thermal properties.

The remains that typically compose the human fossil record often bear cracks, damage, and deformations. The recent rapid development of ‘virtual anthropology’ has provided innovative tools to manage, study, and preserve cultural and natural heritage. Such tools include computerized tomography (CT), laser scanning, photogrammetry, 3D imaging, and rapid prototyping. These approaches can contribute to any archaeological context from the discovery of artefacts to research, preservation, and dissemination.
