The project titled 'Diving into the Machine' explores the use of existing 3D technology for the preservation and dissemination of industrial and agricultural heritage objects. The project runs a series of case studies purposely identifying best practices for the use of 3D models in collection management and presentation. The digitization technologies used vary in quality, efficiency and cost. Each case study researches the sustainability of the 3D files produced and the feasibility of applying them in collection management practice. The project advocates the sustainable use of 3D technology by heritage organizations and raises awareness among 3D service providers about the use of archival standards and guidelines for producing sustainable 3D documents.
