Jeremy Kingsley is a senior manager at Economist Impact and regional practice lead for Technology & Society in Europe, the Middle East and Africa. He leads a regional team of analysts and editors on policy research, consulting and thought leadership programmes exploring technological change and its impacts on society. Jeremy joined The Economist Group in 2017 from Nesta, the innovation foundation, where he oversaw the Challenges of Our Era research programme and design of challenge prizes. He previously edited Nesta's magazine, served as a contributing editor at WIRED, and has spent 12 years covering technology, innovation and business trends as a journalist, researcher and consultant for The Economist, The Economist Intelligence Unit, The Financial Times, Slate, WIRED Consulting and others. He holds a master’s degree in philosophy and economics from the London School of Economics, with distinction, and a first-class bachelor’s degree from Trinity College Dublin.

The invention and introduction of new manufacturing tools, techniques and processes can have profound impacts on the global economy. This has been demonstrated time and again in modern industrial history, from the introduction of the power loom and cotton gin during the first industrial revolution, through Henry Ford’s moving Model T assembly line, to mass production injection-moulding techniques or the just-in-time manufacturing processes pioneered by Toyota in the 1970s.

Each of these chapters of manufacturing innovation upended the established economics of production, to a greater or lesser extent, leading to significant impacts on the prices of goods, the dynamics of supply chains, business models and labour market conditions. The time and cost-savings that resulted from Ford’s production line, for instance, enabled the company to slash the price of its cars, and pay wages that were unheard of elsewhere in the industry.1 This, in turn, enabled newly enriched factory workers to participate in the growing economy as consumers in their own right.

Today, additive manufacturing (AM) technologies have the potential to create another wave of disruptive economic change. Broadly known as 3D printing, the technologies and techniques under this umbrella have been in development since the late 1980s, and have already found a number of uses in mainstream manufacturing, particularly in the medical, automotive and aerospace industries. Instead of creating objects by cutting away at raw materials, or injecting plastic or metal into pre-made moulds, AM methods deposit material layer by layer. The technology has proved popular in the first instance for prototyping, but bears some promise to make industrial manufacturing more efficient by using fewer resources while making it easier and cheaper to build complex and custom one-off designs. Backers of the machines and techno-optimists herald nothing less than a revolution in manufacturing.

Adoption of AM is still, however, at an early stage. Sales of 3D-printed components have grown at a rate in excess of 25% per year since 1989, but still make up a small proportion of global manufacturing output. According to analysis from Wohlers Associates, a consulting firm and industry observer, AM accounted for less than a tenth of 1% of total manufacturing output in 2017.
