The digitisation of manufacturing will transform the way goods are made—and change the politics of jobs too

THE first industrial revolution began in Britain in the late 18th century, with the mechanisation of the textile industry. Tasks previously done laboriously by hand in hundreds of weavers’ cottages were brought together in a single cotton mill, and the factory was born. The second industrial revolution came in the early 20th century, when Henry Ford mastered the moving assembly line and ushered in the age of mass production. The first two industrial revolutions made people richer and more urban. Now a third revolution is under way. Manufacturing is going digital. As this week’s special report argues, this could change not just business, but much else besides.

A number of remarkable technologies are converging: clever software, novel materials, more dexterous robots, new processes (notably three-dimensional printing) and a whole range of web-based services. The factory of the past was based on cranking out zillions of identical products: Ford famously said that car-buyers could have any colour they liked, as long as it was black. But the cost of producing much smaller batches of a wider variety, with each product tailored precisely to each customer’s whims, is falling. The factory of the future will focus on mass customisation—and may look more like those weavers’ cottages than Ford’s assembly line.

The old way of making things involved taking lots of parts and screwing or welding them together. Now a product can be designed on a computer and “printed” on a 3D printer, which creates a solid object by building up successive layers of material. The digital design can be tweaked with a few mouseclicks. The 3D printer can run unattended, and can make many things which are too complex for a traditional factory to handle. In time, these amazing machines may be able to make almost anything, anywhere—from your garage to an African village.

The applications of 3D printing are especially mind-boggling. Already, hearing aids and high-tech parts of military jets are being printed in customised shapes. The geography of supply chains will change. An engineer working in the middle of a desert who finds he lacks a certain tool no longer has to have it delivered from the nearest city. He can simply download the design and print it. The days when projects ground to a halt for want of a piece of kit, or when customers complained that they could no longer find spare parts for things they had bought, will one day seem quaint.

Other changes are nearly as momentous. New materials are lighter, stronger and more durable than the old ones. Carbon fibre is replacing steel and aluminium in products ranging from aeroplanes to mountain bikes. New techniques let engineers shape objects at a tiny scale. Nanotechnology is giving products enhanced features, such as bandages that help heal cuts, engines that run more efficiently and crockery that cleans more easily. Genetically engineered viruses are being developed to make items such as batteries. And with the internet allowing ever more designers to collaborate on new products, the barriers to entry are falling. Ford needed heaps of capital to build his colossal River Rouge factory; his modern equivalent can start with little besides a laptop and a hunger to invent.

Like all revolutions, this one will be disruptive. Digital technology has already rocked the media and retailing industries, just as cotton mills crushed hand looms and the Model T put farriers out of work. Many people will look at the factories of the future and shudder. They will not be full of grimy machines manned by men in oily overalls. Many will be squeaky clean—and almost deserted. Some carmakers already produce twice as many vehicles per employee as they did only a decade or so ago. Most jobs will not be on the factory floor but in the offices nearby, which will be full of designers, engineers, IT specialists, logistics experts, marketing staff and other professionals. The manufacturing jobs of the future will require more skills. Many dull, repetitive tasks will become obsolete: you no longer need riveters when a product has no rivets.

The revolution will affect not only how things are made, but where. Factories used to move to low-wage countries to curb labour costs. But labour costs are growing less and less important: a $499 first-generation iPad included only about $33 of manufacturing labour, of which the final assembly in China accounted for just $8. Offshore production is increasingly moving back to rich countries not because Chinese wages are rising, but because companies now want to be closer to their customers so that they can respond more quickly to changes in demand. And some products are so sophisticated that it helps to have the people who design them and the people who make them in the same place. The Boston Consulting Group reckons that in areas such as transport, computers, fabricated metals and machinery, 10-30% of the goods that America now imports from China could be made at home by 2020, boosting American output by $20 billion-55 billion a year.

The shock of the new

Consumers will have little difficulty adapting to the new age of better products, swiftly delivered. Governments, however, may find it harder. Their instinct is to protect industries and companies that already exist, not the upstarts that would destroy them. They shower old factories with subsidies and bully bosses who want to move production abroad. They spend billions backing the new technologies which they, in their wisdom, think will prevail. And they cling to a romantic belief that manufacturing is superior to services, let alone finance.

None of this makes sense. The lines between manufacturing and services are blurring. Rolls-Royce no longer sells jet engines; it sells the hours that each engine is actually thrusting an aeroplane through the sky. Governments have always been lousy at picking winners, and they are likely to become more so, as legions of entrepreneurs and tinkerers swap designs online, turn them into products at home and market them globally from a garage. As the revolution rages, governments should stick to the basics: better schools for a skilled workforce, clear rules and a level playing field for enterprises of all kinds.

Leave the rest to the revolutionaries.

This video represents the Model-T of 3D manufacturing.

Given today's rate of change, it won't take 100 years to get to a Ferrari. It will take 15 years.

15 years after that, traditional manufacturing will be dead.

You 20th century reactionaries of the left and right... please tell how we revive unskilled assembly line work as a middle class job...

Excellent question! You get it. Ultimately yes, but...

You still have to afford the machine that prints nano-materials based on the design.

That will prohibitively expensive for a long while... but not forever.

Ever seen the Star Trek replicator? This is not exactly the same thing at all, but it's a reasonable approximation for discussion purposes.

In the 19th century, individual artisans created the products we needed.

In the 20th century, massive numbers of people on the assembly line did the same to serve enormously more numbers of customers.

The middle to late 21th century, we will combine digital models with nano- materials to build whatever we need, very fast, and relatively cheap, with very little manual labor.

I understand your point, but the post is about how revolutionary the technology could be to our lives.

Sure, if we wind up in a government police state, all of this could be postponed for decades or even centuries, just like technology was postponed under Communism during the 20th century and also how technology was postponed by the Church during the Middle Ages in Europe.

I completely agree that governments of all stripes are evil. Governments have demonstrated their true nature for all to see. The challenge of our age is with the government monopoly schools... how can Americans can learn from their history, when their history is distorted or not even taught at all...

So, let's take a quick second to celebrate the human spirit and the how it continues to try to move us forward in-spite of government intervention to the contrary.

That was the point of my post about this very revolutionary technology, that has the potential to transform everything...

The only reason they were able to do that was because of what they took from Germany at the end of WW2..... That's how they get pretty much all they have is re-/reverse engineering things/technology they've stolen....

We did, but we kept using and expanding on what knowledge we got from the Nazi's... But it seems like the Commies either couldn't figure out how to keep using that knowledge, or they decided stealing others technology was easier.... OR..... maybe it was both because they weren't teaching people to critically think or think outside the Commie Mantra box!!!! (Kinda like our current school systems)....

The Soviet commies stopped being commies more than 20 years ago (please try to keep up). Since then, they have been dealing with fallout from taking the free market, privatization road.

My Messiah was crucified more than 2,000 years ago.

I do remember George Bush looking into Putin's eyes and finding a soul mate though, is that what you're talking about?

Obozo's not dead...... yet!!!! I thought you guys were athiests (being abortion lovers and all)????

Now why would I be upset about Bush looking into Putin's eyes and finding a soulmate???? Anybody with any sense knows Bush was a moderate (Baby Democrat/Leftard)!!!! And that's the very reason I can't figure out why Leftards hate Bush so much, especially when he was doing the same thing as the ones you vote for!!!!!! Ohhh that's right he has an "R" before his name not a "D"!!!! Besides that I thought Putin was one of youse guyses heroes... How many has he killed with his policies???? (Betcha he's a proponent of ObozoCare)!
