While tariffs and trade wars from the White House may threaten our jobs, peace and prosperity, technology innovations from American business could save us. Just as new technology in energy production and extraction have reduced our dependence on the Middle East, a technology innovation of a very different sort — 3D printing — is already poised to reduce our dependence on Asian factories.
3D printing is a process whereby a specialized printer repeatedly deposits thin layers of material to form a product in three dimensions. These printers can make almost any kind of shape by simply adjusting the software file for the specific product. And in recent years, 3D printing has become cost-competitive with conventional manufacturing for many kinds of products.
