Abstract: In recent years, the global revolution in digital manufacturing has led a mass innovation situation. As an important role in this process, the makerspace is highly fashioned in the world. Fab Lab, one of the makerspace type, provides the facilities and support services that make it possible for entrepreneurs, researchers, and small businesses to access technologies allowing them to turn innovative ideas into working prototypes. Providing ordinary people with modern means for invention does not fit within the conventional categories of education and industry. However, Fab Lab fills this void. This paper states the definition of makerspace and Fab Lab, traces the history of the development of Fab Lab, and then analyzes the five features of Fab Lab in detail. This paper suggests that Fab Lab is a springboard of support for innovators who are engineers and entrepreneurs to move along the entire innovation value chain, is one of the most important parts of this innovation ecosystem. Thus, in the last of the paper, we analyze the Fab Lab innovation ecosystem which includes government organization, industry, and education system.
