Granular Material Conductivity Increases in Mysterious Ways Under Pressure

Scientists reveal how electrical resistance in metallic granular media decreases as the pressure on the micro-contact interface between the grains increases. In a recent study published in EPJ E, a French team of physicists made systematic measurements of the electrical resistance – which is inversely related to conductivity – of metallic, oxidised granular materials in

100x Faster, 10x Cheaper: Desktop Metal 3D Printing System

Desktop Metal – remember the name. This Massachussetts company is preparing to turn manufacturing on its head, with a 3D metal printing system that”s so much faster, safer and cheaper than existing systems that it”s going to compete with traditional mass manufacturing processes. We”ve been hearing for years now about 3D printing and how it”s
