PRESERVING 3D PRINTED ARCHITECTURAL MODELS - THE HERITAGE AND CONSERVATION OF ARCHITECTURAL DESIGN PROCESS

This article examines the preservation challenges posed by 3D printed architectural models as emerging heritage artefacts. Focusing on models from the Zaha Hadid Foundation collection, it compares the condition of earlier traditionally made architectural models with later 3D printed examples. The study used a site visit and sample condition survey, combining field notes, photographs, and non-invasive visual inspection of six models to assess materials, condition, and signs of deterioration. Findings indicate that traditionally made models from the 1980s and 1990s remain relatively stable, while more recent 3D printed nylon models show greater discolouration, fragility, and breakage. The article concludes that 3D printed architectural models present distinct conservation risks, particularly due to the limited understanding of the long-term behaviour of early 3D printing materials, and argues for improved analytical methods, storage strategies, and monitoring to support their preservation as part of architectural heritage.
