Could 3-D printing revolutionize the parts and service department in the dealership of tomorrow? 3-D printing, also known as additive manufacturing, refers to the processes used to create a three-dimensional object in which layers of material are formed under computer control. It is already being used in a number of industries, and it’s likely that agriculture could be next. Robert Saik, author of The Agriculture Manifesto and founder of The Agri-Trend Group, thinks 3-D printing is one of the drivers that will shape agriculture in the next decade. He says the growth and adoption is going to be exponential, meaning adoption will start off slowly before it quickly becomes mainstream.
