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

Appraisal of the volumes of fluid in a carbonate reservoir will typically require a reliable predictive model. This can be achieved by combining studies of well-exposed carbonate successions with 3D models in order to obtain reliable quantitative data. In this paper, we present a detailed outcrop study and a 3D porosity model of a well-exposed Oligocene carbonate ramp (Salento Peninsula, southern Italy) to investigate the nature of small-scale facies and porosity heterogeneities.

Introduction: Osteoarthritis (OA) is the most common degenerative joint disease and it is mainly characterized by articular cartilage damage, synovial fibrosis and osteophyte formation. Osteophytes are osteo-cartilaginous outgrowths that involve the bone structure of osteoarthritic joints. In this study we analyzed how osteophytes evolution leads to a rearrangement of the stresses and strains within the subchondral trabecular bone.

The study of the fossil record is fundamental to understand the evolution of morphological traits. Fossil remains often appear fragmented and/or deformed by taphonomic processes, which result in cracks, missing portions and deformation of the original morphology. In paleoanthropology, cranial remains are at the same time the most informative and sometimes the most badly deformed fossil portions, often presenting themselves broken, partially incomplete, and/or distorted.

This paper presents some of the results obtained from the integrated use of 3D surveying techniques and illustrates some types of analysis and graphic representations that can be conducted and reproduced. The case study concerns the church of San Nicola in Montedoro that is one of the oldest in the city of Martina Franca in the province of Taranto (Italy) and presumably dates back to the fourteenth century.

Caves have been used by humans and animals for several thousand years until present but, at these time scales, their structures can rapidly change due to erosion and concretion processes. For this reason, the availability of precise 3D models improves the data quality and quantity allowing the reconstruction of their ancient appearance, structure and origin. However, caves are usually characterised by lack of light, high percentage of relative humidity, narrow spaces and complex morphology. Thus, quite often the traditional topographic instruments cannot be employed.

This paper springs out from a collaborative project jointly carried out by the FabLab Saperi&Co and the Museum of Near East, Egypt and Mediterranean of Sapienza University of Rome focused at producing replicas of ultra-thin archeological finds with a sub-millimetric precision. The main technological challenge of this project was to produce models through 3D optical scanning (photogrammetry) and to print faithful replicas with additive manufacturing.
