As industry 4.0 means a wireless and sensor technology,then how 3D printing and additive manufacturing comes under industry 4.0? Kindly someone elaborate i will be very thankful
3D Printing is a 'standalone' production technology that can be integrated in the concept of Industry 4.0, but not neccssarily. Industry 4.0 describes digitally-enabled, horizontal and vertical interconnection (across the supply chain and across company functions) and data interconection from product development, production, usage, to recycling. 3D Printing (or more generally, additive manufacturing technologies) can be integrated here, having for instance effects on supply chains and spare parts logisitcs:
