And Now What? Three-Dimensional Scholarship and Infrastructures in the Post-Sketchfab Era

The transition of Sketchfab, a widely used platform for hosting and sharing 3D cultural heritage content, to Epic Games’ Fab marketplace has raised concerns within the cultural heritage community about the potential loss of years of work and thousands of 3D models, highlighting the risks of relying on commercial solutions for preservation and dissemination. This shift, together with the unprecedented investments by the European Commission on infrastructures for digitised heritage, present a critical opportunity to restart conversations about the future of 3D scholarship and infrastructures for cultural heritage. Using a mixed-methods approach, this paper analyses data from a literature review, two surveys, a focus group, and community responses to Sketchfab’s announced changes. Our findings reveal critical user requirements, including robust metadata and paradata for transparency, advanced analytical tools for scholarly use, flexible annotation systems, mechanisms for ownership, licensing, and citation, as well as community features for fostering engagement and recognition. This paper proposes models and key features for a new infrastructure and concludes by calling for collaborative efforts among stakeholders to develop a system that will ensure that 3D cultural heritage remains accessible, reusable, and meaningful in an ever-changing technological landscape.
