Digital manufacturing and Industry 4.0 are nothing new. 3D printing/additive manufacturing, industrial robots, self-driving vehicles, drones, augmented/virtual reality, Industrial Internet of Things (IIOT), edge computing, and more are making manufacturing more agile, flexible, and personalized. So-called smart factories are based on a set of manufacturing concepts intended to streamline business. These optimizing principles include full connectivity, agility, lot size of one, and parts, subassemblies, and products moving on automated guided vehicles (AGVs).
