The research in mini, micro and desktop factories originates from the early 90's and has continued since then by developing the technological basis and different technological building bricks and applications in the field of high- precision manufacturing and assembly of future miniaturised and micro products. This has paved the way for mini, micro and desktop factories which are seen as one potential solution for what kind of production by improving space, energy and material resource utilisation and answering to the needs of design for postponement and customer-close customisation and personalisation. This paper presents one case application for flexible micro factory. Application area is macro world assembly system in miniaturised form. Current trend in this research is the miniaturisation of macro world machines and systems towards more sustainable production technologies.
