This article presents the firsts phases of interlocking between community, city and digital manufacturing infrastructures, focused on the case study of Puerto Williams, Chile, the southernmost city of the world. Its process of digital urbanization for sustainable development based on technological education for the local school and community, by combining digital fabrication for the design and production of local solutions. Located in Navarino Island, Puerto Williams has no high-speed internet connection, and it does not produce any energy and goods, being utterly dependent on ships that bring liquid gas, products and raw materials. In January of 2019, a fully-equipped Digital Fabrication Laboratory opened, and fibber optic internet expected to arrive by the end of 2020. These conditions establish the basis of digital urbanization process for rural, pre-digital and isolated communities.
