3D Printing Is Changing the Way We Think

July 21, 2015

Surveys indicate that more than 30 percent of the top 300 largest global brands

are now using or evaluating 3D printing (often with printing technology

in-house) whether for prototyping and other innovation projects or in actual

production of what they sell. Over 200 universities and colleges already offer

3D coursework in their curricula covering aspects of not only 3D printing but

also 3D scanning and design. To my mind, there is no question that 3D has

reached, as Dartmouth s Richard D Aveni argues in a recent HBR article, a

tipping point.

Even Terry Wohlers, founder of Wohlers Associates and publisher of the most

cited research tracking the rise of 3D technology, is impressed. In a recent

email exchange he told me: We re seeing a level of investment in 3D printing

that we have not seen in the past not even close. As much of a champion as

Wohlers is for the technology, he marvels at how the pace is picking up: It s

really very interesting, and to some extent, mind-boggling, especially given

that 3D printing has been around for more than 25 years.

But perhaps there is a simple reason that the tipping point is arriving now. I

think it s connected to the recent arrival of very affordable desktop 3D

printers which means it isn t only big corporate R&D departments that are

coming down the 3D learning curve.

I saw this last year, when I spent eight-plus months traveling to hotbeds of 3D

innovation across America in a specially outfitted RV. Our tour took us to

government agencies like NASA and big corporations like GE, but we also hung

out in makerspaces, hackerspaces, and other places where creators were using

less elaborate versions of the tools.

I met, for example, Jeff Tiedeken, founder of the uniquely named business

Monkey Likes Shiny. He is a skilled metal fabricator, but that label doesn t do

him justice. Really, he is a renaissance man creating models that quickly move

from digital to physical, in the form of metal and also many other materials.

He uses 3D printers and also CNC routers, metal bending machines, waterjet

cutters, and other tools. That day, for example, he was happy to show me the

gravity bikes he designed for maximum speed on downhill coasts. Wild cycles,

for sure. He regularly volunteers at the San Francisco Exploratorium because he

wants to help young people learn to make things with their own hands

especially things designed from scratch. When I contacted him last, he was in

Hawaii helping community-college students machine up parts for a satellite.

People like Jeff and students all around the world are embracing newly

accessible technology to make the things they couldn t make as easily before.

For evidence, just look at the popular crowdfunding site Kickstarter. Over the

past couple of years, entrepreneurs have used it to launch no fewer than 300

3D-printer-related campaigns and many of them have funded at levels in the

millions of dollars. This must be what it felt like in the earliest days of the

automobile when, depending on which source you check, something like

1,800-2,800 auto startups were launched in the span of a few decades.

And in fact, it s also like the most recent days of the automobile era. The

Uber of 3D printers is 3D Hubs, a platform that allows designers, once they

have created 3D software files, to find 3D printer owners in their locales who

can, for an agreed fee, print them out of the desired materials. Already,

nearly 20,000 printers have registered with the site globally most of them

individuals who bought their machines for personal use but are not running them

at anywhere near their full capacity. That network footprint, 3D Hub reports,

means that one billion people on this planet already have a 3D printer within

10 miles of their homes.

My point is not that all these artisans and hobbyists and their shop-scale

technology are collectively producing enough 3D-printed output to put a dent in

the overall economy. For me, the most important tipping point isn t about how

many manufacturers have changed, it s about how many minds have. Thanks to more

accessible technology, we are now reaching a critical mass of people who, when

they think about how things are made, think in a different way. You could say

they are thinking in 3D.

It is simply a different world when the time lapse between creating a design

and having a tangible object of that design in hand is tiny. One inventor I

know says that with traditional CAD tools, he would spend 15-16 hours to build

a new model, but with web-based tools he has cut that down to only 15-20

minutes. Once you begin to assume that your iterations will be so quick, many

aspects of how you think about developing and delivering products change.

In the California leg of the 3DRV roadtrip, I talked with Jason Lopes of Legacy

Effects, best known for its ingenious contributions to The Avengers, Avatar,

and other Hollywood films requiring special effects, animatronics, and creature

designs. It was Jason who first helped me see how having a new level of access

to a technology can lead to different ways of thinking. The company has always

relied on service bureaus with very high-end equipment to render its character

designs, but a few years ago, it purchased a 3D printer to use for simple tasks

in-house. Unexpectedly, that ended up changing a lot about its design project

workflows. At the same time, having 3D printing technology right at hand opened

people s minds to possibilities for using it beyond the modeling of the

characters themselves for example, to print the parts, jigs, and fixtures

also needed to complete work and deliver it to clients. Jason says that having

a 3D printer in the office has changed the way he and his colleagues approach

design overall.

The same can be said about the 3D software tools that are becoming widely

available. As just one example, apps now exist to allow smartphone users to

snap some pictures of an object and get a digital 3D rendering of it. That

means, of course, that you can print a scale model of something like an

action figure of yourself, for example. But more importantly, if some

approximation of an object you wish to create already exists, you now have a

starting point for it rather than beginning with a blank screen. Beyond being a

timesaver, that might spell the difference between pursuing your novel idea or

never getting around to it.

3D technology has a special ability to capture people s imaginations. In

Florida, we connected with 350 seventh-graders at the Electa Lee Middle School

in Bradenton, where educator Bekka Stasny invited us to demonstrate the

process. My 11 year-old son was the natural spokesman for this stop, showing

off simple toys he had created en route with an app and printer we had on board

the 3DRV. You would not guess that 350 middle school students could watch and

listen with such rapt attention.

It might not always occur to us that this is true, but the people who work as

operations management executives in large manufacturing concerns are also

people with outside lives, who take interest in new trends and who have hobbies

and side projects suited to their skills. Some of the people going to work in

today s big businesses are young people who were not long ago learning about 3D

in classrooms and science museums. Some aren t so young but have kids doing

that. Some are makers or even casual entrepreneurs, earning extra cash

selling 3D printer access to their neighbors. The more people like this who

arrive in a workplace, the more likely that workplace will be to undergo a

change. This is how tipping points are reached: not when some key percentage of

big companies has installed a technology, but when enough people see its

possibilities. Expect to see global manufacturing transformed as more people

see new ways to make things, because they re thinking in 3D.

TJ McCue led the 3DRV project across the USA in 2014. Version two of that

project is called GoExplore3D which continues to visit and explore what brands

and individuals are doing in 3D technology.
