The replicator

WHEN great designs are turned into products compromises are made. The beautifully sculpted “concept” cars that regularly appear at motor shows never get built, at least not in the form they left the design studio, because they are inevitably too difficult and expensive to engineer for mass production. For decades this has meant products have […]

ONE of the great advantages of 3D printing is being able to escape the constraints of traditional production processes, and to make things with unique shapes. The powerful computer-aided design programs that are used to run 3D printers help engineers achieve this. Algorithms calculate the most efficient structure required to achieve the lightest weight and […]
