Metal bellows are produced by rolling, welding, hydroforming and electroforming , but only electroformed bellows feature seamless construction and isotropic properties, unaffected by the heat of welding or the strains of cold working.
NEWS: Come to the Inside 3D Printing event in New York City ! The event runs from April 22-23 2013. We have arranged for reprappers (that's you!)
It’s a natural thing to do: you want to know how big something is, so you measure it by pinching your fingers. Sadly, unless you’re a cyborg from the future sent back in time to measure things, it doesn’t really help – unless, that is, you’re equipped with the Smart Fingers. A concept design featured over on the Yanko Design blog, and the brainchild of designers Choi Hyong-Suk, Jung Ji-hye and Yoo-Jin Park, the Smart Fingers are augmentations for your puny human hands that allow you to measure any distance quickly and easily.
A team of tinkerers over at the McGill University in Montreal have created an eco-friendly 3D printer which uses plain water to print ice sculptures. As profiled over on Cory Doctorow’s Boing Boing , the team have successfully modified their FAB@HOME desk-based rapid prototyping machine to create fully realized 3D sculptures from ice based on commands sent to it from a PC running CAD/CAM software. While 3D printers are nothing new – and are often used by engineers to rapidly create a physical prototype of a new part, allowing real-world tests to be carried out without the expense of having a whole production line created specifically for a handful of prototypes – the use of ice is an interesting departure from the traditional plastic, wax, or starch-based materials most commonly used in such devices.
