Top Five Reasons

to integrate 3D Printing into Your Product Development Lifecycle

Rapid prototyping was a game-changing innovation for industrial

designers when it was introduced two decades ago. Previously,

prototypes would be constructed from wood or metal in woodwork or

machine shops. The process took weeks or months and the cost was

often so prohibitive that designers skipped prototypes entirely and went

directly from CAD to tooling. Often this meant that design flaws were

not identified until manufacturing began, leading to expensive re-work

and lost time.

Rapid prototyping technology has progressed significantly over the

years improving on both the cost and quality fronts. Circa 2000, Objet

Geometries introduced the PloyJet™ and PolyJet Matrix™ technology

to the market, a jetting process of photopolymer resin in ultra-thin

individual layers that builds models. The resin is simultaneously cured

with a UV light during the layering process; an approach that allows

for printing of several materials including flexible, rubber-like material

and composite Digital Materials™. The result is a much higher-quality

surface finish and highly accurate geometries. Unlike many competing

technologies, Objet’s PolyJet and PolyJet Matrix are clean processes

suitable for office environments.

So why should you consider using 3D printing technology as

part of your product development process?

Objet surveyed its’ base of users from various markets including consumer

goods, consumer electronics, medical device, education, research,

entertainment and others, why they made the investment, and based on their

responses crafted these Top Five Reasons to Integrate 3D Printing into Your

Product Development Lifecycle.

1.  Designers can prototype more iterations without blowing the timeline or budget

3D printing – particularly when done in-house – enables

design teams to quickly produce a high-quality, realistic prototype with

moving parts, at relatively low cost when compared to other methods

such as machining or outsourcing. This means teams can use prototyping

on projects where it wasn’t feasible in the past due to time or cost


“We needed a faster, more streamlined system: one that would let us do

the engineering, development and production of clinical trial-ready devices

in-house. We had heard about rapid prototyping and were very excited

about seeing how it could help us.” Andre’ A. DiMino, Vice Chairman

of the Board, Executive Vice President and Chief Technical Officer, Ivivi

Technologies. The integration of the Eden350 into the product development

and production cycle at Ivivi has been an unqualified success, yielding a

positive return on investment in less than one year. “We’ve cut an average

of five to six weeks off the clinical trial device production process,” said


2. Better collaboration resulting in improved design and manufacturability

The ability to quickly produce real working prototypes that

teams can see and touch helps bridge the gap between the virtual CAD

design and the final product. Design and manufacturing engineers can

use these prototypes as a tool to better communicate how a design looks,

feels, and operates allowing for the product design to integrate with

manufacturing at an earlier stage in the development lifecycle.

Brian McLaughlin from Orchid Design, a division of Orchid Orthopedic

Solutions, says “Often, something the designer sees on a rapid prototype

– such as an undercut, or some other area of difficulty – will cause them

to tweak the design before it goes to the customer or to machining. Or, a

customer will say, ‘You created it just as I described, but now that I see it, I

think we need to change X, Y or Z.’ 3D printing has definitely had a major

impact on the quality and manufacturability of our designs.”

According to Jon Fawcett from Fawcett Design, his team now uses the 3D

printing system for “Anything and everything. Functional prototype, aesthetic

prototypes, rigid molds for urethane cast parts, rapid manufacturing… our

Objet 3D printer is very versatile. We can now do same-day turnaround on

prototypes, which in turn allows us to do a lot more prototyping. We can

very quickly see if something will work; we no longer have to guess or take

a chance.”

3. Field test with prototypes that resemble the final product providing insight into potential design flaws

More prototyping means more opportunity to evaluate whether or not a

part will function as intended. Prototypes allow designers to catch potential

flaws before incurring the exponentially higher costs of re-tooling and

rework, reducing some of the risk of introducing new products.

Shawn Greene from Fender Musical Instruments describes a recent project

to develop a light-up front panel for an amplifier. Using 3D printing,

Greene produced prototypes of the panel using a clear material, tested it

with different types of lights and discovered that light didn’t deflect they

way they thought it would. “We had to adjust the design to make it

work,” says Greene. “In the past, we would not have done a prototype for

that kind of part because it would have taken too long and cost too much

money. So by the time we noticed that problem we would have already

paid for tooling, and then we would have had to pay for amendments for

the tool. The ability to rapid prototype in house saved us a fortune on that


4. Improve customer satisfaction

3D printing can help improve satisfaction for both internal

and external customers. Designers using 3D printing have the

ability to quickly produce realistic prototypes for internal

decision makers, as well as external clients. Having the ability to touch

a real world concept, combined with testing functionality allows all

constituents of the design and manufacturing process to make better

product decisions. The bottom line, 3D printing helps organizations get

better products to market faster than ever before.

“Frequently during a project, clients request design changes or wonder

how particular changes may impact the overall aesthetic,” said Piet Meijs,

Rietveld Architects. “Our Objet system lets us create a whole new model

right away, and that wows the client every time.”

“Now that we have it, we tend to use it for all our projects, and the

feedback from our customers has been terrific. It’s pretty amazing to see

someone’s face when you give them a real model that brings their idea to

life. It really blows them away.” -Brian McLaughlin, Orchid Design

5. Seeing is believing

Design is both an art and a science that starts with

imagination. 3D printing helps quickly transform something

imagined into something that can be seen and touched. Prototypes are

often used to help sell new concepts, so the more realistic the prototype,

the better.

‘With the Objet Connex500, we don’t have to rely on imagination to

convey how an overmolded part will actually look, feel and operate.’

– Dan Mishek, Vista Technologies

“No matter how good our 3-D graphics are, there is nothing like a model

in your hands…” – Henry K. Kawamoto, M.D., D.D.s, UCLA Medical


“You can show someone something on paper all day long, but when you

give them a real part that they can touch, they really get excited” -Shawn

Greene, Fender Musical Instruments

Additional considerations

Cost and time savings are the primary drivers for incorporating 3D printing

into the product development process. But for some organizations, other factors

influence the need for in-house technology.

The ability to drive revenue – pertaining primarily to service bureaus – by offering

3D printing services or use the services as a way to lure customers into giving

them ancillary business such as manufacturing. When Fawcett Design was

evaluating rapid prototyping technologies they settled on a high-end 3D printing

system because it offered the speed and finish quality required to have the

competitive edge as a rapid prototyping service provider.

Organizations oftentimes weigh the need for in-house technology against the

efficiencies of outsourcing. A typical maturity curve is to start off with outsourcing,

and then bring it “in house” as the volume of projects grows. Many Objet

customers have realized that an in-house solution has significant additional

benefits like the ability to protect the confidentiality of their designs. Customers

have also found that the 3D printing system can be useful for many different

applications some of which were originally unexpected. Having this technology

at their fingertips gives them the freedom they need to be more creative and

efficient with their designs.

A 3D printer for every need

Whatever the driver, this paper demonstrates a myriad of benefits to integrating

3D printing into your product development process. In recent years, 3D printing

technology has matured to the point where there are a number of different types

of systems on the market, from entry-level to high end. Chances are a system exists

that meets your organization’s exact requirements.
