Interesting speculation on how fabs could create metal objects in the future. Today fabs use simple powdered or liquid media that is easily melted (see CandyFab – it uses kitchen sugar!) This makes it easy, but produces objects that can be fragile or at least not particularly durable. The idea is that by depositing metallic dust in a vacuum, a “cold weld” occurs and solid metal objects can be created.
