President Obama said in his 2012 State of the Union Address, “3D printing . . . has the potential to revolutionize the way we make almost everything.” Can there be any greater endorsement than from the world’s most powerful man? 3D printing is the commonly used term for additive manufacturing. It is a manufacturing technique which creates physical objects from digital designs. It uses a process called layering which produces multiple layers of material until the product is ready. It can be applied in a large number of diverse fields like aerospace & defence, retail, automobile manufacturing, fabrication as well as supply chain optimization. 3D printing in the supply chain market can have a profound impact on transforming this process. It allows weeks to be shaved off manufacturing time and also helps companies reduce their carbon footprint related to production and distribution. It produces very little waste, which makes it popular with environmentalists and the government. It enables manufacturers to “print on demand”, reducing both inventory cost and allowing customized products for individual customers.
