Envisioning the Desktop Fabricator
mkl writes "Yesterday I fantasized about a generator of matter. Not a laser plotter for carving 3d objects, but a device that will assemble any given object from its base, out of atoms. I was thinking about a device that can find its place under the roofs of all the people working on PCs all over the world. So I fantasize about it at work and what do I see in the Wired News newsletter? 'Any product, any shape, any size -- manufactured on your desktop! The future is the fabricator.' Heh."
http://www.bathsheba.com To start building a model from my 3D file, the design is built up, one layer at a time, from steel powder held in place by a laser-activated binder. ... This produces a porous steel part that is about 60% dense. ... The model is heated, the stems are dipped in a crucible of molten bronze, and capillary action causes the bronze to wick throughout the piece. Counterintuitive to say the least, but apparently it works very well.
