Carrying out many successful projects on architecture and design as well as technology and science, 3D is now used for a water screen. These architectural pieces that we come across with in hotels, plazas and shopping malls, can be manufactured with 3D printing. Combining imagination and technology, this water screen almost paints with water by creating various patterns.
Prepared for Temps de Flors festival held between the dates of 7-15 May in Spain, Girona, this water screen includes some letters, patterns and visuals can be seen as its flows. The product is the result of eight months hardwork from eight members of Base42, a 50-strong group of technology lovers, aged between 15 and 74, who specialize in drones, robotics, 3D printers, and more. While there are no real flowers inside the impressive water curtain, the team, led by project director Josep Maria Escubedo, wanted to participate in Temps de Flors in their own special way: by creating a technological system which could ‘draw’ flowers, as well as other images and words, in water, on a 3 x 2 meter water screen. The result is a stunning piece of visual art, especially at night, when lights illuminate the falling jets to display the floral visuals in all their atmospheric glory.
The mechanics behind the water curtain are, according to its creators, relatively simple:Â 500 
liters of water are contained in a tank at the base of the system. A pump pushes that water to the top of the system at a rate of 80 liters per minute, where the water then passes down through the 128 3mm diameter 3D printed nozzles, forming what appears as a 3 x 2 meter ‘curtain’. To create different patterns in the water curtain, the 64 3D printed nozzles can rapidly alter the direction of the water to one of two nozzles in a pair.
