Hi, I like stamps a lot, so I was happy to find out, that there is an easy and cheap way to make stamps by using Shapways and Sugru! You probably know Sugru already. If not, it's an air-curing rubber that can be formed by hand. It bonds to most materials and turns into a strong, flexible silicone rubber overnight. This is perfect for making stamps. I made a negative-stamp-form via Shapeways and pressed it on a thin layer of Sugru. Here are some photos of the first attempt. I'm already happy with the result, but I'm sure it can be still optimized. The good thing: you can make as much stamps as you like and you don't need much of the Sugru material, so it's also very cheap!
