The open day at Fablab Amsterdam has been discontinued. We may set up a different programme for people who want to work at our Fablab later. In the meantime, there are many places where you can use digital fabrication machines.
We helped to create the 'Maakplaatsen' at the public libraries (OBA) in Amsterdam, that have a standard Fablab machine set available and also provide public access. For more information about their open days, turn to the website maakplaats021.com - in Dutch. Also in Amsterdam: the ZB45 maker space with an open day on Tuesday and Makerversity in Amsterdam (paid membership model).
Outside Amsterdam, there are Fab Labs in a number of places, like Alkmaar, Amersfoort, Utrecht and Lelystad. Visit this website for a complete overview of all Fab Labs in The Netherlands.
