| Abstract: |
During the 20th century plastics became established in works of art because they enabled artists to create more complex and unconventional shapes. The complexity of these forms and heterogeneous installations are difficult to capture with 2D drawings alone. Therefore, in the field of restoration and conservation there is always the demand for better methods to document art and cultural assets. 3D scanning with a laser scanner or a structured white light scanner appears to be a promising technique. In the preservation of historical monuments, 3D scanners have proven over the years to have a safe application when used on inorganic and natural materials. However, the study of the interaction of 3D scanning with organic and synthetic materials has not yet been undertaken. Plastics that have undergone some alteration and that have weak areas within their molecular structure could be adversely affected by exposure to the additional energy source emitted by 3D scanners and could degrade more rapidly than non-exposed plastics over time. In this thesis, examinations were undertaken by running a series of tests on untreated, laser-exposed and white light-exposed samples to analyse the influence of 3D scanner radiation on Cellulose nitrate, Polyvinyl chloride, Polymethylmethacrylate, Polycarbonate and Polyurethane.
