In July 2012, Kinetic Rain was installed at Singapore Changi Airport by MKT AG as the world's largest mobile sculpture. It consists of hundreds of motor-driven floating drops, suspended on thin steel wires and creating different images within a 15-minute choreography. The installation was conceived by artists and programmers of Berlin-based Art+Com AG. toolcraft was asked to develop and manufacture the drops, including material and process selection.
The drops had to be light enough so they will not overload the linear motors - but not too light to prevent them from whirling and banging onto each other in the head space of the hall. Furthermore, a highgloss copper-coloured surface had been specified. This and an ideal weight of approx. 170 g (6 oz.) resulted in the decision to manufacture the drops in aluminium.
Due to their shape and specified weight, the drops could not simply be machined out of an aluminium block, but had to be manufactured as twin-shell hollow bodies, including a tight-fitting fine-pitch thread for assembling the shells and an impeccable copper-coloured highgloss coating – all within very ambitious budget limits per piece.
With the drops for Singapore Changi Airport's world spectacular Kinetic Rain, toolcraft once again demonstrated its core competences in turning and milling. In a comprehensive total solution – from the ideal material and optimised design to precision manufacture, including copper coating.
