A shimmering salt crystal rises into the sky in front of the Churer Tor, surrounded by several small crystals made from recycled material using a 3D printing process. The Churer Tor, once known as the Salt Gate, refers to its historical function as an access point for the salt trade into the city and forms the symbolic framework for the installation. Accompanied by specially composed sound collages by artist Loulou Raven, a multi-layered dialogue unfolds between material, sound and space. In the midst of the historical architecture, a floating dialogue between space, surface and radiance is created.
The central crystal was produced in a continuous 68-hour 3D printing process – a technical maximum for monolithic objects using this method. The material used was rPETG, a modified, translucent filament made from recycled polyethylene terephthalate, which originally comes from disposable medical containers. Its special translucency is influenced by environmental factors such as temperature and humidity during the printing process – comparable to the natural conditions under which real crystals grow.
The installation combines technological precision with organic aesthetics and draws attention to new forms of sustainable design. It symbolises the connection between nature, the material cycle and the digital future.
