Rapid
Prototyping in 2006 Throughout
the past three years, there have been many positive developments, but few
major breakthroughs. From this narrow slice of history, a fair conclusion
would be that RP is condemned to small, incremental changes during the
next six years. However, when the industry is viewed through a larger
historical window, major developments become obvious:
The birth of
desktop printers.
The rise and
fall of equipment vendors.
An 11-fold
increase in the number of RP machines installed worldwide. In analyzing the
computer industry, Bill Gates once said that people tend to over estimate
what will happen in three years and underestimate what will occur in six.
We hold the same theory for the RP industry.
What will the next
six years yield? Here are the predictions from our
"Perspective."
10 Predictions for the
Future Each of the remaining nine
predictions either results from or helps to bridge the chasm.
2. A 24 percent decline
in system manufacturers. Survival for today's 21 RP machine
manufacturers is not guaranteed. Several are on life support and are
unlikely to sustain existence in their present form. Nine of the current
vendors will fail or be acquired by another organization.
In November 2000, Japanese
RP machine maker Teijin Seiki announced that it would acquire NTT Data
CMET, the largest Japanese maker of RP machines.
Around the same time,
Helisys decided to call it quits after nine years of manufacturing and
selling Laminated Object Manufacturing (LOM) machines. Sadly, these two
companies will no longer be with us - companies that helped shape the RP
industry. Others will follow.
Although the going will be
tough, four start-up companies will throw their hats into the competitive
arena, bringing the total to sixteen.
3. A Fortune 500 company
explodes onto the stage. As the chasm is crossed, the RP industry will
become too attractive for major players to ignore. 3D Systems may have
enabled this development by paving the way for Canon. On June 14, 2000, 3D
Systems announced that Canon Sales Company would market ThermoJet systems
in Japan. Canon may be using this distribution strategy to survey the RP
landscape to plan its entry into the world of 3-D printing. Whether it's
Canon, Hewlett-Packard or Fuji-Xerox, an established company will
manufacture, distribute and support a 3-D printer.
4. A common tool in
education. A significant plunge in the price of an RP machine will
make it possible for even the most budget-strapped schools to claim
ownership. With special educational offers, hundreds of public and private
schools throughout the U.S. will purchase an inexpensive, but impressively
functional, 3-D printer.
It is a common practice of
large companies to seed the educational market with their technology to
make it the tool of choice. Perhaps Canon will lead the way.
5. Intolerance for the
three H's. Hazards, hassles and headaches will not be tolerated.
Partial solutions, dangerous chemicals, challenging operations and high
maintenance costs will not be acceptable in an RP evaluation. Ease of use
and low cost of operations will be key decision-making factors, and the
manufacturers will have responded to the demand.
As alternative methods of RP
develop and mature, companies will phase out established processes in
favor of machines that are safe, reliable and affordable to own and
maintain.
6. The Internet takes
hold of RP transactions. Overburdened project engineers will not have
the luxury of spending days to secure quotes, outsource prototypes and
manage the supply chain. Using the wide-reaching power of the Internet,
corporations will gain confidence that they are receiving the best value
for their money. Companies will embrace custom e-commerce solutions that
integrate with their internal accounting and ERP systems to minimize
redundant entry of transactional data. These Internet tools will permit
them to work with internal and external customers and service providers in
a way that reduces time and effort.
7. In living color.
The preference for color is obvious; color photography, color charts and
graphs, color monitors and color CAD models. Color enhances the
communication potential for RP. Boring, lifeless, bland prototypes will
not be acceptable when brilliant reds, blues and greens are available.
However, for this to happen, the penalty in dollars and time must become
nearly non-existent.
Color is already being used
in an interesting fashion. The results of finite element analysis are
being applied to RP using Z Corp.'s Z402C color 3-D printer. The effect is
an easily interpreted FEA stress plot.
8. Digital supercedes
physical. Already, digital models (e.g., CAD solid modeling) have
reduced the need for physical models and prototype parts. Today, companies
routinely produce multiple versions of a new design, digitally, before it
is fabricated. As CAD and computer simulation tools improve, and as
product development teams are forced to further reduce time-to-market, the
number of prototypes will shrink.
However, the diminishing use
will apply only to the current scope of prototyping. As technology
advances and new applications arise, the overall use of these additive
processes will increase.
Like the fast and
inexpensive document printers that derailed the idea of the paperless
office, 3-D printers will find their way into companies of all shapes and
sizes. As the investment - of both time and money - to produce these
models drops to an insignificant amount, organizations will be printing an
astonishing number of models for a wide range of alternative purposes.
9. Unthinkable
applications emerge. The vast array of potential applications is
exciting. Organizations will rely on methods of RP for sculpture,
architecture, mold flow analysis, molecular modeling and a wide array of
other interesting and unusual uses.
Breakthrough applications
have already emerged. RP has been used in forensics to solve murder
mysteries; it is a critical component in creating "invisible"
braces for orthodontics; and it has helped those in dire medical
situations.
Although there is movement
in this direction, some of the most exciting applications have yet to be
conceived.
10. RP translates to
Rapid Production. Perhaps solid freeform fabrication is a better term
to describe the class of technology that we today refer to as RP. Indeed,
rapid prototyping is the single largest application of this technology,
but it can extend well beyond prototyping.
In six years, companies will
routinely use methods of RP for the production of manufactured parts.
Investigations are already
under way for the appropriate use of RP to manufacture relatively small
parts in volumes of hundreds and even thousands.
Mass customization - should
it ever be realized - will most likely rely on some form of the technology
that we know today as rapid prototyping.
Conclusion Consider the transitions
from NC to CNC, from mainframe to notebook and from the Model T to the
2001 model year. It didn't happen in a few years, it took decades. Break
any one of these technologies down to six-year increments and you will
find major advances.
History will repeat itself
in the RP industry. In the year 2006, what is commonly accepted and
practiced today will be long forgotten. While incremental changes will
continue, expect and demand major leaps forward.
