This study aims to integrate the theoretical framework of Critical Regionalism with the production method of Fab Labs, proposing a sustainable regional regenration through digital fabrication technologies. It addresses issues such as global architectural homogenization and loss of local identity. The main objectives include examining community governance in local Fab Lab production, analyzing cases where digital fabrication processes utilize regional materials, and proposing a collaborative open-source design and production network that defines architecture as a shared resource. The research methodology comprises a comprehensive literature review of Critical Regionalism and the characteristics of Fab Labs as regional commons. It includes an analysis of case studies where Fab Labs have contributed to urban regeneration by utilizing regional materials in fabrication. Selection criteria for the case studies focus on Fab Lab-led projects in Europe post-2000, particularly those aligned with sustainable development goals (SDGs) and circular economy principles. The study also investigates global networking initiatives, such as the Fab City Global Initiative. The findings reveal that Fab Labs foster sustainable architectural practices by promoting local material use, open-source design sharing, and decentralized production. Fab Labs are instrumental in bridging traditional craftsmanship with modern digital fabrication, resulting in context-sensitive architectural outcomes. They enhance local identity and provide a collaborative framework for sustainable urban commons. This research suggests that integrating Critical Regionalism with Fab Lab production can redefine architectural practices as the networked commons. It proposes that local Fab Labs, through global networks, can become hubs for sustainable innovation, enhancing regional distinctiveness while engaging in global collaboration. The findings support the development of community-driven governance models for shared architectural resources, contributing to the revitalization of declining urban areas and fostering resilient local economies.
