A DIGITAL RECONSTRUCTION PROCEDURE FROM LASER SCANNER SURVEY TO 3D PRINTING: THE THEORETICAL MODEL OF THE ARCH OF TRAJAN (ANCONA)

In recent years, the technologies for creating reality-based 3D models were enhanced and propagated in a large number of applications and research fields. This great evolution is due to the fact that these technologies are very useful, or rather ideal, to preserve, disseminate and restore cultural heritage, thanks to digitization and the realization of digital copies based on additive printing. In particular, 3D printing and virtual reality have determined the increase of a new field for data survey: the museum fruition. Therefore, they are becoming increasingly important. The aim of this article is to show the connection and the relationship between the development of the latest technologies and the cultural heritage: a digital reconstruction procedure from laser scanning survey to 3D printing of theoretical model, realized with a virtual reconstruction reality-based.
