From retail goods to medical implants and even food, 3D printing
technology promises to change the way we think about everyday things. It’s
difficult to predict what impact it will have on manufacturing but, whatever
the precise effects, they are likely to be deep and permanent.
3D
printing, also known as “additive manufacturing”, refers to processes where an
object is put together by layering materials under programmed commands. Objects
can be of almost any shape or geometry and are produced from digital model data
or other electronic data sources, such as an Additive Manufacturing File.
The
advent of 3D printing opens the way for manufacturers to significantly reduce
the production cost of their goods by eliminating many steps in the
manufacturing process, such as casting and welding metal. It also reduces the
complete production process to no more than three to four key players. With 3D
printing, what would have initially been a series of stages of production could
be cut down to a designer at one end, and the printer or “manufacturer” at the
other. The middle players would most likely be suppliers of raw materials or
“ink”.
Disruptive Power of
3D Printing and Impact on Economic Security
Such
reductions in the manufacturing process could affect both regional and
international production networks, possibly resulting in reduced capital
requirements, warehousing and other logistics and transportation needs. This
change in production systems could potentially alter the very idea of nations’
economic security.
It
could, for instance, wreck countries’ carefully laid development plans for
creating employment and investment in logistics and warehousing, regardless of
economic development level. What might happen to global production networks
under such an influential technology?
The
introduction 3D printing has the potential to create a new production system by
unleashing a disruptive power that the world has not experienced since the
industrial revolution. This disruption could turn the global supply chain and
existing production processes – perfected over 100 years ago with the Ford
assembly line – on its head.
The
Ford assembly line centred on the idea of economies of scale. It posits that if
you produce large numbers of a particular product, each additional unit
produced will be less expensive to manufacture.
End of the
Assembly-line Economy?
The
specialisation of the assembly line required only low-skilled workers, who
could easily be taught simple repetitive steps. Standardised parts and more
efficient assembly drastically reduced the cost of production and allowed more
workers to be hired. With more labour being hired and steady incomes assured,
people could afford the products that they were helping to build because of
their low cost and easy availability.
All
this led to a growth in consumption, and manufacturing-led rapid economic
development, along with supply chain networks, spread across the globe after
the Second World War. Taking root first in Japan, then Hong Kong, South Korea,
Taiwan and Singapore, this global trend even transformed the most populous
nation on earth, China, in the past 30 years.
It’s
very likely that evidence of manufacturing success from these many countries
has motivated initiatives such as the Indian government’s 2014 “Make in India”.
The effort is part of a wider agenda to transform India into a global design
and manufacturing hub.
After
initiation of the program, India emerged the top global destination for foreign
direct investment (FDI), receiving US$63 billion and surpassing both the United
States and China. The initiative is premised on the fact that FDI in the
manufacturing sector will create jobs for the masses. But 3D manufacturing
technology poses a serious threat to this effort and others like it.
Supply Chains and
Beyond
The
uniqueness of 3D printing lies in the fact that it reduces complexity. Parts
and components, assembly steps, and costs can all be significantly reduced. The
pioneer of the assembly line itself, the Ford Motor Company now uses 3D
printing to produce and assemble prototypes. According to the company’s
additive manufacturing technical expert, these prototypes can be ready for
testing in under a week, down from eight to 16 weeks and cost just a few
thousand, rather than US$100,000.
What’s
more, 3D printing provides potential for new design possibilities that can be
tweaked or changed according to preference, even at the last minute. Ideas
about stocks and logistics will evolve as companies might very well be shipping
designs in the future instead of products. These designs can then be printed or
“manufactured” by the end-user at the location of their choice.
This
promises reduced capital requirements for physical infrastructure considering
3D printing services could function just as well in small spaces rather than
taking up large areas as traditional manufacturing sectors do. The need for warehousing
and transport, including transborder shipments, can also be reduced.
It’s
in this way that 3D printing could challenge economies of scale in the
manufacturing sector and shorten the global supply chain networks, from
multiple sites of production to a network that consists of material suppliers
for 3D printing and the final producers at or near the end-user.
It
could become the harbinger of the move from mass production of certain goods to
a more bespoke economy, where everyday mass-produced goods are created with
made-to-order specifications. This will lead to the production of many
variations of a product but in low quantity. Such a scenario would not be
static. Currently, 3D printing seems to fit neatly into the high-mix and
low-volume combination. But over time, mass production could be disrupted by
this technology.
Major Changes Ahead
The
direct implication of this is an extensive disruption in global supply chains
with jobs in manufacturing, logistics and warehousing being affected across
many countries. Along with these, cargo transportation and port configuration
would also be transformed due to the changes from economies of scale to the
economy of one or few.
With
such a drastic technological tsunami in the manufacturing landscape, land-zoning
policies might have to be reassessed. On one hand, 3D printing could
potentially eliminate many large-scale assembly plants. On the other, many
small and medium enterprises could serve as 3D printer services, now producing
bespoke products.
Would
it then still make sense to retain the current divide between industrial zones
and non-industrial areas? Countries that have allocated huge resources in the
development of industrial estates, with the intention of attracting
manufacturing plants to create jobs, would be required to get back to the
drawing board to reconceptualise future manufacturing plants.
And
such changes may motivate a review of initiatives such as Make in India, even
with record-breaking FDI pouring into the country. Given such rapid technological
changes, this particular initiative may not necessarily translate to greater
job creation despite being a few years away from a “printed economy”.
Even
the factory of the world, China, will not be spared the shocks of this new
wave. With the advent of 3D printing technology, the industrialisation
blueprint for southwest China would necessitate more than just cost
competitiveness or the excellent infrastructure that the country has created on
its east coast over the last 30 years.
Another
current initiative likely to be affected is the ASEAN Economic Community
Blueprint 2025. Its key objective is for the region to become a highly
integrated and cohesive economy by enhancing regional participation in global
supply chain networks. But, again, the pursuit of global supply chains in the
manufacturing sector will need to be critically re-examined.
3D
printing may well necessitate transformation beyond the manufacturing sector.
It will directly affect urban planning and land usage policy; sea and airport
development for cargo; and perhaps, more importantly, job creation for the
masses in developing countries as a pathway to upward mobility. All these
potential upheavals prompt the fundamental question – do we need to recalibrate
our economic aspirations in light of such influential technology?
