Working prototypes The various prototypes for the D-HUB exposition www.dhub-bcn.cat are being fabricated at the FabLab cut with 3-axis milling machine. Using Alucobond 5mm, which provides lightness as well as stiffness, these prototypes can be attached to multiple forms of organization providing ample flexibility for the space. After being cut they are then manually folded and then secured with bolts inside. The  models are developed by Areti Markopoulou and Panagiota Tsekoura.
