Shapeways, the latest consumer-oriented 3D printing service that's making a huge splash across the internet, slipped in an announcement last month about a new print media: "White Strong & Flexible". This unusual material enables designers to make objects that bend!
The example shown above illustrates the possibilities. While most printing services do not permit mixing of material within a single print (unless they are using Objet's multi-material printer) you can print out components separately using different materials and then assemble the pieces together later.
