After we brushed away 3D printing as the technique for producing our UWater stations, we started looking elsewhere for inspiration. Let's build metal stations, we thought. The drawings were finalized. But an unforeseen challenge arose — how do we make the station in the shape of a drop, as we had intended? The manufacturing process can be a lot of fun, but it’s also very expensive. We’ll keep looking and working on our prototype until we find the right solution. Stay tuned!
