This document examines the sustainability of several FabLabs across Asia and identifies common business models. It analyzes 7 FabLabs from India, Philippines, and Japan of various sizes and entities. The labs studied rely on a mix of revenue sources like access fees, workshops, projects, and in-kind support. Three main types of revenue are identified based on number of payers, payment size, and expertise needed: access fees have large numbers of small payers and low expertise; workshops have medium numbers and payment size and medium expertise; and projects have small numbers but large payment size and high expertise. Sustainability remains a question as many labs struggle with re-investment after 5 years without consistent revenue streams.
