The Future of Additive Manufacturing
3D printers affect both the professional and consumer markets. The
increased sale of these machines over the past few years has taken
additive manufacturing (AM) mainstream more than any other single
development. 3D printers have helped spread the technology and made it
more accessible to students, researchers, do-it-yourself enthusiasts,
hobbyists, inventors, and entrepreneurs.
Designers and engineers
are considering new approaches when developing products for additive
manufacturing. The old habits of “design for manufacture” could become
a thing of the past, as AM can make almost any shape or geometric
feature. As AM systems and materials are used more frequently for
manufacturing, expect to see new products that previously would have
been very difficult or impossible to manufacture.
manufacturing industry is expected to continue its double-digit growth
over the next several years. By 2016, Wohlers Associates believes that
the sale of AM products and services will reach $3.1 billion worldwide,
as shown in this chart. By 2020, the industry is expected to hit $5.2 billion. (The numbers in the vertical axis are in millions of dollars.)
future development with the greatest impact may be one that is
impossible to anticipate. Terms such as “outlier” and “paradigm change”
describe this phenomenon, an event or development from beyond our
narrow vision that is difficult to predict and changes everything. In
the context of the AM industry, this could be a new material, a new
application, or an industry certification. Or it could be a development
outside the industry, such as a web interface for product co-creation,
global security or trade issue, or an energy or climate crisis, to
speculate on a few possibilities.

Wohlers Talk: Jim Kor and His Car
are reasonably good that you have read about the Urbee car. It is the
brainchild of Jim Kor, an intriguing individual that I had the
privilege of meeting in October 2011 in Winnipeg, Canada. He gripped my
attention, from start to finish, as he presented the history of Urbee
at a special conference organized by the Industrial Technology Centre
of Winnipeg. It was not difficult to notice Jim’s passion for designing
what could become the most energy-efficient car on the planet. With a
drag coefficient of 0.15, it is quite possibly the most aerodynamic. A
third-generation Toyota Prius has a drag coefficient of 0.25.
a mechanical engineer, Jim designed farm machinery for Winnipeg
manufacturers before starting his own firm, KOR Product Design, 30
years ago. Urbee was conceived 15 years ago as Jim’s third vehicle
project. Today, a core team of a dozen people make up KOR EcoLogic, a
Canadian company that is wholly owned by them, with a goal of getting
Urbee into mass production. I was struck by Jim’s obsession with Urbee.
days before meeting Jim, he had driven the car some distance as part of
an open highway test. The two-passenger vehicle is designed to be
exceptionally fuel efficient, safe, and inexpensive. It uses electric
motors and is capable of 200 mpg when running on an 8 hp
ethanol-powered engine, which serves as a backup. The car is expected
to reach 70 mph.
On September 21, 2011, the BBC reported that
Urbee had been in development for many years, but its finished
3D-printed body had never been seen in the public. That was true until
its unveiling at TEDxWinnipeg in September 2011 and again two weeks
later at the Winnipeg conference that we were attending. About 100
people in attendance got to see it and two of us were invited to sit
in the driver’s seat. With the support of Stratasys, FDM additive
manufacturing technology was used to produce the entire body of the
car. The Urbee team did an outstanding job with the finish of the body.
truly hope that Jim and his team can secure the investment needed to
take the car into production. Urbee deserves a chance in the
marketplace and I suspect it will get it. The car has received an
impressive amount national and international press, so it may be only a
matter of time before the right people come together. Jim’s best-case
scenario would make the car available in 2014. The price might be
$50,000 in limited production, but it could drop to $10,000 in mass
