Obtaining Replicas of Historical Plasterwork Using Photogrammetric Techniques and Additive Manufacturing

Abstract

The use of techniques such as photogrammetry and laser scanning for the acquisition of geometric data in the field of heritage and conservation has become considerably widespread in recent years due to the great advantages they offer. In addition to being highly accurate, these techniques do not require direct contact for data acquisition. In this way, the integrity and preservation of the element to be recorded is guaranteed. Based on the three-dimensional registration of elements of great heritage value, it is possible, among many other applications, to reproduce them. Replicas have an essential role to play in restoration, heritage dissemination, analysis and study. This work analyses the suitability of different additive manufacturing techniques for obtaining moulds from which to reproduce heritage elements of great value, registered by using techniques such as photogrammetry or laser scanning. As a case study, different Mudejar plasterwork panels located in the Real Alcázar of Seville have been selected, contributing to their enhancement. The models obtained have provided the basis for the manufacturing of different moulds, from which singular details of the studied plasterwork have been reproduced. © 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG.
