In response to the world’s currently largest humanitarian crisis, design agency LATRA established a Fab-Lab inside a refugee camp in Lesvos – Greece, to co-create together with the refugee community innovative products responding to community needs directly on the field. Based on the experiences of refugees, attention focused to a universally distributed humanitarian tent, which required complex and expensive logistics to arrive onsite, only to become obsolete a few months, weeks or days later. CORE RELIEF is a 3D printed component, enabling refugees to recycle the standardized humanitarian tent into new domestic products, thus improving the sustainability and resilience of their settlement. Focusing on a critical product that is distributed in every humanitarian and environmental crisis across the world, means our solution though locally produced, can be globally applied. The design is distributed free and open source, so it can benefit 65 million displaced people across the world.
