Renishaws laser melting system is a
pioneering process capable of producing
fully dense metal parts direct from 3D CAD.
From tooling inserts featuring conformal
cooling, to lightweight structures
for aerospace and high technology
applications, laser melting gives designers
more freedom, resulting in structures
and shapes that would otherwise be
constrained by conventional processes
or the tooling requirements of volume
production. It is also complementary to
conventional machining technologies, and
directly contributes to reduced lead times,
tooling costs and material waste.

What will manufacturing look like once additive
manufacturing is in more widespread use? DiSan-
to Technology, subject of the article on page 4,
offers clues. 3D printing of metal components now
accounts for a notable share of this frms produc-
tion. If manufacturing in general is on its way to
adopting additive processes to a similar extent,
then the differences we see at DiSanto, along with
other adopters of additive manufacturing for end-
use parts, are suggestive of the shift we are likely
to see in the very nature of part production.
How will manufacturing look different once
additive production has matured? Here are some
of the ways:
1. Fewer employees. An additive machine
needs a person to oversee it, but that same
person could go on to oversee four, six or eight of
the machines just as effectively. With additive pro-
duction, expanding capacity does not necessarily
entail expanding the production staff.
2. Office-like plants. Additive machines are
quiet and clean. A shop with nothing but 3D
printers running feels more like a lab than a plant.
DiSanto set up its additive machines in what used
to be an offce. Since the room remains tidy and
free of shop noise, it still seems like an offce,
particularly given the staff member working at a
desk within this same room.
3. Simple machining. Some of what is done
through fve-axis machining today can more
easily be done through 3D printing. Geomet-
ric complexity adds challenge to a machining
process, but in an additive process, a complex
part is about as easy to produce as a simple one.
In an additive future, it seems likely that relatively
simple cuts will account for a larger share of total
CNC machining activity.
4. Easy onshore/offshore. To start production
on an additive manufacturing job, little is needed
in the way of setup or tooling. For companies with
access to additive machines in multiple countries,
this means the choice of where to produce can
be made as quickly as the digital fle can be sent.
Jobs will shift rapidly across national borders.
5. Super JIT. Additive machines seem slow,
but their cycle times are short compared to the
overall lead times for other processes. Today, a
responsive manufacturer provides just-in-time
delivery of known and established parts. Addi-
tive production will bring just-in-time delivery of
previously unknown and unestablished parts.
Quick production will be possible even for new or
custom designs.
6. Super unattended. See point 1. A room
flled with additive machines might represent the
ultimate in unattended production. Such a shop is
less like a factory for making parts and more like
a farm for growing them.
7. Tooling just for high volumes. The
DiSanto-made parts on this issues cover used to
require forging dies, but no longer. In the future,
an increasing share of part numbers will be com-
ponents that formerly needed engineered tooling,
but now can be made through 3D printing. Dies
and molds will still be made and used (some will
even be made additively), but we will associate
this tooling with high volumes to an even greater
extent than we do today.
Something to Add

Reimagining Implants
A medical-industry contract manufacturer that built its
reputation on CNC machining is now helping its customers
realize the advantages of additive manufacturing.
Ronald Dunn, vice president of medical-
industry contract manufacturer DiSanto
Technology, says the photo on this page
illustrates the future of spinal cage implants.
The part shown is actually a scaled-up model
DiSanto uses to illustrate this design to medical
device companies. Surgeons and other medical-
industry professionals who are knowledgeable
about spinal surgery look at this model and im-
mediately appreciate the beneft: bone ingrowth.
A spinal cage implant essentially serves as
a spacer between adjacent vertebrae that are
fused together during spinal surgery. The part is
usually machined, whether from a plastic (PEEK)
or from a titanium alloy. Because it is machined,
the part is typically dense and solid.
This new design is self-evidently better, Dunn
says. Because the parts mesh allows the pa-
tients bone to grow into it, the body accepts this
implant such that the ft improves over time. Few
would contest the value of this ingrowth, he says.
Its just that machining has never offered a way
to create this mesh geometry. The mesh seen
here was possible because this part, instead of
being machined, was produced through additive
manufacturing. The part was grown in succes-
sive layers on an electron beam melting (EBM)
machine from Arcam.

DiSanto now has two of these machines,
along with one Arcam employee on-site, as part
of a partnership with Arcam aimed at increasing
both the demand and the capacity for additive
manufacturing of medical parts in the United
States. DiSanto sees so much potential in this
method of manufacturing that the company is
building an expansion so it can add four more
Arcam machines.
Historically, DiSanto has been a machin-
ing business. About 55 CNC machine tools run
at its Shelton, Conn., site. Dunn says additive
manufacturing will expand the use of these
machines. Thats because practically every ad-
ditively produced medical part needs machining
of critical features as a secondary step, he says.
Plus, many implants produced additively need
complementary machined components that are
part of the surgery.
However, additive manufacturing will also
change which parts the company machines,
Dunn says. Certain components being machined
today will be produced additively instead, after
they are redesigned into more functional forms
that can only be produced through additive
manufacturing.
The spinal cage is an example. DiSanto has
long made these cages through machining, and
continues to do so, but company engineers saw
how additive manufacturing could create a better
design. The company produced the prototype at
its own expense so it could pitch the idea to cus-
tomers. Going forward, Dunn expects to win work
for additive manufacturing by taking this same
initiative with other parts that are currently made
through machining. The companys machine shop
has thus become its prospecting feld.
Supplier Challenges
The partnership with Arcam works this way,
says Dunn: The additive machine maker gives
DiSanto a measure of exclusivity in pioneering
the market in the United States for manufactur-
ing implants through EBM. Meanwhile, Arcam
gets DiSantos commitment to the technology.
From Arcams perspective, DiSanto is the ideal
size, Dunn says. His company is big enough to
be a player in implant manufacturing, but small
enough that it was willing to reinvent itself in
pursuit of the promise of additive production.
The opportunity to make this change came
at the right time. DiSanto was facing challenges
Historically, this parts porous bone-integration
surface has been produced through plasma
spray, generating an imprecise outer form.
EBM makes it possible to print the bone
integration layer directly into the form,
precisely controlling the geometry.
This might be a picture of the future of batch production.
This collection of hip stems was produced in a single additive
manufacturing cycle. Not only were many pieces nested into
this build, but various sizes are seen here as well. In the past,
each of the different part numbers would have required its
own forging die.

are considerable. Owing to
the need for forging tooling,
a newly designed hip stem
in the past would have
required a lead time of at
least eight weeks, but with
additive manufacturing, that
same newly designed hip
stem can be manufactured
within 48 hours.
Effciencies such as
these are suffcient to justify
additive production, Dunn
says. However, these sav-
ings are just the beginning.
The still-greater beneft to
DiSantos customers is the
design freedom additive
manufacturing gives them.
They can now design their
own precisely controlled
bone integration geometry
instead of just accepting
the random surface ge-
ometry of a plasma spray.
This is huge. Then there is
the most important beneft
of all: An additive-manu-
factured implant is likely to
function better within the
patients body.
The reason for this also
relates to dimensional con-
trol. Plasma spray is such
an imprecise process that
bone reamers in surgery
are oversized because of it,
Dunn explains. The reamer
produces an oversized
cavity in the bone to accommodate the uncertain
dimensions of the sprayed part. By contrast, with
additive manufacturing providing control over
geometry, the reamer can now be right-sized.
The implant can therefore press-ft into the bone.
Surface contact between implant and bone is ex-
tensive, rather than merely occurring at a few high
Here is the perfect
example of a part that
could only be produced
through additive manu-
facturing. This hollow
titanium sphere has a wall
thickness of 1 mm. Ronald
Dunn demonstrates the strength
of this structure by standing on it.
with multiple suppliers that additive
manufacturing neatly addressed. One
involved the porous surface for bone
integration on implants. Historically,
this surface has been added through
plasma spray coating. DiSantos
source for that coating had recently
been purchased by a competitor.
Meanwhile, DiSantos supplier
for castings had begun to demand
aggressive 15-day payment terms.
Manufacturing is all about cash fow,
Dunn says.
Additive manufacturing provided
welcome relief in both situations. The
additive process makes plasma spray
unnecessary, because the 3D printed
part can have the porous layer just
printed into the design. Also, additive
manufacturing makes casting un-
necessary, since this part-generating
technology is essentially a foundry in
a box.
Dunn says, They say additive
manufacturing machines are ex-
pensive, but I dont see
it. The cost of these
machines is easy
for us to balance
against the
supplier-related
costs we no
longer have to
pay.
The su-
preme example
of this might be the
elimination of forgings. An
implanted titanium hip stem might come
in 20 different sizes, requiring 20 different forging
tools at more than $7,000 per tool. With additive
manufacturing, all of that tooling expense is gone.
In fact, representatives of the 20 different part
numbers can all be built within the same cycle,
as needed, simply by nesting the different parts
within a single EBM build. The time savings in this
0214AM_Feature 1.indd 6 1/16/2014 3:04:09 PM

AdditiveManufacturingInsight.com February 2014 7
points of the spray. As a result, the bone integrates
with the implant that much more quickly.
Machining Changes
The savings in CNC machining are also signifcant,
Dunn says. While its true that an EBM surgical
implant almost always needs machining, that
machining is slight because the part is near-net-
shapemuch nearer to net shape than casting or
forging. As a result, all of the machining passes on
an additive part are inherently fnishing cuts. The
costs related to roughingincluding time, material
and toolingno longer have to be paid.
In addition, this fnish machining tends to con-
sist of relatively simple cuts. A part such as a hip
stem has historically been produced through com-
plex fve-axis machining, but Dunn says he expects
DiSanto to rely on fve-axis machining much less
in the future. Geometrically complex features can
be produced more easily through EBM, he says,
and additive manufacturing can also be used to
give the part extra features that make the remaining
machining easy. The hip stem might be generated
with a boss for a vise to hold during milling, for
example, with this sacrifcial feature cut away when
machining is done.
Yet in spite of these savings, the machining
activity at DiSanto is likely to grow with additive
manufacturing, he says. The reason is not just be-
cause additive parts need to be machined, but also
because they create the need for other machined
parts. An aspect of DiSantos machining activity
that might be surprising to an outsider is the extent
to which the shop machines plastic. Implants such
as hip stems and knees are metal, but implants
often come with plastic components that are part of
the implants operation. Knee implants, for exam-
ple, come with plastic liners that essentially serve
as cartilage. Through various workholding and
toolpath techniques, DiSanto has become prof-
cient at quickly producing these non-metal parts.
As additive manufacturing expands the number
and variety of metal implants DiSanto produces,
Dunn expects his company to have even more op-
portunity to apply its expertise at machining these
related plastic components.
DiSanto has two Arcam additive manufacturing machines. They
run so quietly and unobtrusively that the company currently has
them in a space that used to be an offce.
The company has about 55 CNC machines in-house. With
the advance of additive manufacturing, the role of CNC
machining will change, the company says. Some machined
parts will be produced additively instead. However, because
of the machining needs of additive parts, and because of
the need for complementary machined components, machin-
ing activity is likely to increase.

Functional Components
from Plastic Droplets
The essential aspect of the machine and part pictured here is
that it is possible to produce one-off plastic parts and small-
volume batches from 3D CAD fles using standard granulate
and without requiring a mold. Arburgs AKF plastic freeforming
process produces functional components directly from plastic
droplets. This fexible part is an example of a two-component
application using a combination of hard and soft materials
polyamide (PA) and thermoplastic elastomers (TPE).
The part was produced without using support structures.
It was made from conventional, low-cost standard granulates
instead of resins, powders, strips or otherwise pre-assem-
bled materials. The produced part is not a prototype, but a
fully functional, high-quality component.
In the AKF process, the machine is flled with the standard
plastic granulate, a heated plasticizing cylinder melts the
plastic in the discharge unit, a nozzle closure uses fast open-
ing and closing movements to produce the plastic droplets
under pressure, and the part is additively built up.

Molds and Cores Built in Days without Tooling
This photo shows a diesel engine cylinder head, along with part of the sand mold
and some of the sand cores that were required to cast it. This sand mold and the
cores were created using a 3D printing process developed by Voxeljet.
According to Tom Mueller, principal of Thomas J. Mueller and Associates,
casting such a cylinder head requires several tools, including patterns for the
cope and drag (the top and bottom parts of the sand mold), and a number of
core boxes (molds used to create sand cores that will form undercut features
in the head). This process can take thousands of dollars and several weeks
to complete. Castings with complex fow situations, like cylinder heads and
pumps, often can only be optimized by an iterative design-build-test-redesign
process, he says. However, the cost and time required to create the tooling for
each design iteration makes the process very costly and time consuming.
With the Voxeljet process, molds and cores can be built without tooling in a
few days, making this iterative process more cost- and time-effective. In fact,
a designer can now simultaneously evaluate several design alternatives to
further cut the time required to optimize the design, Mueller says.
The possibilities for additive manufacturing have been growing at a fast pace
and, according to one technology player, the industry is now focused on bring-
ing the buzz down to practicality. The Euromold trade fair in Germany last
December offered an array of unique and exciting AM displays, but the real story
was the actual technologies and applications for the manufacture of functional
parts, including end-use components and industrial tooling. On the following
pages is a sampling of what we saw at this show.
Cost-Effective Casting
ExOnes largest additive manufacturing
machines print parts in sand for use in metal
casting. Making casting mold components
directly in sand, without any need for a pattern
or core box, enables not only more cost-effec-
tive casting as the caption at left describes,
but also casting of complex geometries that
would not have been practical or even pos-
sible with conventional casting molds. The
sand-printed part above is an example of an
intricate, core-like component that was easy
to produce through 3D printing.

Machining Hidden Features
DMG Moris Lasertech 65 hybrid solution can do rough
machining, deposition and fnishing on one machine, allowing
a part such as the one pictured here to be built and machined
with fve axes. The additive features grown off of the central
OD show the machines ability to reorient the part to build
in different directions within the cycle. The drilled holes and
milled mating surfaces were created using the machines
conventional machining capability.
Parts such as this can be built as much as 20 times faster
than with powder bed solutions, DMG Mori says. Parts can
also be built up in sections, with
milling operations used on important
areas in between. Support structures
are not necessary, and wall thick-
ness can range from 0.5 to 5 mm
(0.020 to 0.2 inch).
Dr. Greg Hyatt, DMG Moris chief
technology offcer, explains that
an advantage of this process is that
it can be used to build up a number
of layers, of the same or various
alloys, which can then be machined
to the required accuracy before the
next layers are added. These part areas would not normally
be accessible for milling cutters, meaning hidden features can
now be machined.
Material Savings
A new SLS platform from 3D Systems was used to produce
the pump part shown here without tooling. This process is
designed to generate a lot of parts fast while producing
only about 20 percent material waste.
Of note is the pumps complex shape, which
would typically require long lead times if tooling
were needed, but no tooling was required. This
part is strong enough to use directly in the feld on
a machine or an engine, according to the company.
The ProX 500 3D printer used to produce this
part builds on the companys patented SLS
technology and, together with its newly developed
DuraForm ProX materials, can deliver end-use-ready
thermoplastic parts more quickly and more accurately
than previous 3D printers.

High-Density, Non-Porous,
Chemically Pure Metal Parts
Direct metal sintering (DMS) technology allows the accurate,
direct printing of high-density, non-porous, chemically pure
metal parts (such as this one printed by 3D Systems), yielding
high repeatability, reliability and quality.
Metal end-use parts and tooling inserts can be directly
and quickly created via this process, cutting out intermediate
and time-consuming steps required in traditional manufactur-
ing. This includes complex parts and shapes that would be
nearly impossible to produce using traditional methods. In
addition, direct-metal-sintered tooling can be used in the pro-
duction process within a day or two after manufacture, rather
than after waiting weeks for the tooling to be machined.
A selection of materials can be used in DMS systems,
including stainless steel, tool steel, super alloys, non-ferrous
alloys, precious metals and alumina used in the aerospace,
automotive and medical device industries.

Digital Molding Factory
A digital molding system from Stratasys closes the gap between rapid prototyping and alu-
minum/steel tooling. It gives engineers the option to perform required regulatory and safety
tests on the actual product earlier in the process, validating the design and moving forward
to production.
Approximately 60 toy race cars like the one shown above were made by injecting
polypropylene (PP) into the small mold pictured here, which was printed from digital ABS
material in an Objet Connex260 printer. This run provided a sense of the design, including the
snap fts that connect the car body to the wheels, which were formed in a separate mold.
Printing the mold for the car body took about six hours, and it cost less than $1,000.

Two Separate Functional Parts,
One Design
An oil separator and cooler that traditionally function as two
separate parts were produced as three components in a direct
metal laser sintering (DMLS) platform from EOS, then welded
into a single part measuring 450 260 180 mm (17.7
10.3 7.1 inches). This was later reproduced in one piece, as
a concept design, using the companys new EOSINT M 400
modular, extendable DMLS system above.
This part was built from EOSs Aluminum AlSi10Mg alloy for
a Rennteam Uni Stuttgart racing car. The upper section of the
oil separator/cooler uses centrifugal force to deposit oil from air
(its rough surface enhances this effect), and the lower portion
serves as the oil tank, offering maximized surface area for cool-
ing. The original part was used in a formula-student racing car
and proved to have great performance characteristics, EOS says.
With a build chamber measuring 400 400 400 mm
(15.8 15.8 15.8 inches), the EOS M 400 enables the
automated manufacture of high-quality large metal parts. The
system consists of a setup station separate from the build
area with an automated system in between that clears loose
powder from completed parts.
Use of DMLS is said to have contributed to a reduction
in the oil separators size and weight. A highlight of the
new system is that it separates job preparation and cal-
culation from the building process, enabling the job fle to
be prepared at the designers desk and then transmitted
via a network to the machine. In this way, the machine
focuses solely on building the parts.

LMD Toughens Automotive Dies
Laser metal deposition (LMD) can increase automotive die
life and reduce setup times. That is what researchers at the
Fraunhofer Institute for Production Technology IPT, toolmaker
Mhlhoff Um-formtechnik GmbH and other Green Carbody
Technologies Innovation Alliance (InnoCaT) partners set out
to prove during Euromold with their new universal,
reproducible, industrial-use LMD process.
During LMD, a laser beam carefully melts the surface of
the die and the fller material to produce a local layer that
guards against wear on the die surface. This treatment,
which is completed in fractions of a second, is designed to
increase the robustness and resilience of the stainless steel
die at critical points.
The group rebuilt a conventional fve-axis milling machine
(pictured here)which can be installed within the current
manufacturing processfor the automated LMD of forming
dies. According to Fraunhofer, this processes increases the
lifetime of dies by more than 150 percent, improves the
quality of components and makes it possible to plan setup
times with greater precision.
Another key part of the LMD system is integrated software
that enables the laser surface treatment processes to be
controlled in a clear, reproducible way. All necessary process
parameters are transmitted to the machine without the need
for any interface. Processes can be simulated in detail and
optimized in advance of actual processing operations.
Mold with Eight Complex,
Conformal Cooling Channels
via Laser Melting
The conformal temperature control arrangement
pictured here requires complicated design workeight
outlets of 3 mm (0.12 inch) in diameter and practically
identical fow conditions branching out from a 10-mm
(0.40-inch) inlet. According to Renishaw and LBC
Engineering, this design guarantees uniform, highly
turbulent coolant fow and effcient heat transport in
each channel. These inserts were laser-generated on
a Renishaw machine with a 0.5-mm (0.02-inch) margin
per wall. Conventionally made inserts cannot usually
be pre-worked in such detail before hardening, so this
means reduced hardening work for cost savings that
partly offsets the cost of the laser melting process.

14 AM Supplement
Stratasys has introduced a nylon material designed to offer greater resistance to breakage
and better impact strength than other fused deposition modeling (FDM) materials. Specifcally
engineered for the companys line of Fortus 3D production systems, FDM Nylon 12s elon-
gation-at-break specifcation is said to surpass that of other 3D-printed nylon 12 materials
by as much as 100 percent. This can enable manufacturers in aerospace, automotive, home
appliance and consumer electronics industries to create durable parts that can stand up to
high vibration, repetitive stress or fatigue.
FDM Nylon 12 is available for the Fortus 360, 400 and 900 systems. It is initially being
offered in black and is paired with SR110, a new soluble support material that the company
says is optimized for the nylon material.

Ultrasonic AM Machine Welds
Metals into 3D Parts
The SonicLayer 4000 from Fabrisonic LLC features the
companys patented ultrasonic additive manufacturing (UAM)
technology, which uses sound to weld together metals into
solid three-dimensional shapes.
Because this process uses solid state welding, it lends
itself to welding dissimilar metals, including aluminum, copper,
stainless steel and titanium. And, unlike a metal fusion process,
UAM avoids brittle inter-metallics that form during the com-
bination of two or more metals, the company says. Periodic
machining operations help create further details on UAM-built
objects, including deep slots; hollow, latticed or honeycombed
internal structures; and other complex geometries.
The SonicLayer 4000 features a 9-kW welding head for
additively manufacturing the solid metal parts and a three-axis
CNC mill with a 25-hp, 8,000-rpm spindle for machining
them. The 4000R model also offers a fourth axis that rotates
underneath the traditional three-axis motion system. This
additional axis positions a cylindrical part under the welding
system and enables 3D printing of metal features on the OD of
a shaft, cylinder or pipe.

An Outlook for Additive in 2014:

Looking back at 2013, it should be known as the Year
of the Printer. Advancements and accelerations in
both funding and media exposure broadened the
audience from boutique fabrication frms and defense
special programs to garage hobbyists, universities,
Fortune 50 companies and small-to-medium enter-
prises. What does this mean for 2014? Is there critical
mass to further accelerate or sustain these eforts?
By following America Makes (the National Additive
Manufacturing Innovation Institute [NAMII]),
fnancial markets (from initial public oferings to
quarterly earnings) and industrial leaders like General
Electric, the answer to the frst question may entail
tangible data points, such as increases in supply chain
partners, approvals of new standards and qualif-
cations, and exposure to advancements in novel
materials and additive processes.
It may be a bit too early to evaluate critical mass
for two main reasons. First, 2013 included such an
explosion of activities that such eforts may still be in
forming stages, whereas 2014 may be the realization
stage. Second, while additive manufacturing provides
many non-traditional benefts, most of these are held
captive to very traditional ways of thinking. In other
words, the industrial world may not be pervasively
ready yet.
For 2014, there will be continued basic research in
our national and university laboratories to explore
the potential viability of new functional materials,
process monitoring and equipment integration.
Expect another round of funding for America Makes
projects, which fll technical and transition gap activ-
ities, and, more than likely, additional mergers and
acquisitions within the industrial sector.

Tere are frms that continue to increase brick-and-
mortar resources, technical capability and know-how
in order to better meet dynamic customer require-
ments. It will be interesting to see how the startups
in this industry defne their diferentiation. An area of
increasing interest seems to be in catering to locali-
ties and afnity groupsexploiting the low-volume,
customization enablers of additive manufacturing.
While many government programs, and the private
sector for that matter, have historically performed
in silos, there seems to be an interesting phenom-
enon lately to share data publically. Whether it is a
private-public partnership, such as America Makes, or
an efort funded by the Defense Advanced Research
Projects Agency (DARPA), like the Open Manufac-
turing program, there are more public forums to
present and share outcomes than ever before.
Tis better enables the diligent to connect strategic
dots, create value to advance the state of the art and
not reinvent the wheel, as well as brings more diversi-
fed backgrounds to the productivity table. Advance-
ments will continue in additive manufacturing in
the arena of optimization for material selection for
product requirements, process parameter mapping
to as-designed properties, and improved equipment
calibration and reliability.
Should the maker communityMaker Faire, DIY
and educational outletscontinue their entre-
preneurial march forward, look to fnd more local
manufacturing and creativity incubators manifesting
organically, as they have at MITs Fab Lab network and
Ideaspace. Common attributes for success include
agility and latitude in creativity, and, quite frankly,
those who realize ideas seem more adept than most.
To that end, the maker movement is a compliment,
if not a necessary element, in advancing the state of
additive manufacturing, not only in the United States
but in the global market as well. When this is coupled
with mentorship resources found in competitive
programs like the FIRST Robotics Competition, a new
innovation landscape begins to emerge.
Te additive manufacturing perspective looks contin-
uously challenging and promising for 2014, where the
world may be literally what you make of it!

goaL For ImtS 2014
Im looking to seek out new, innovative
products and processes in manufacturing
that challenge the status quo. While attending,
I hope to network with other like-minded
individuals. Its not often that you get the
opportunity to be in the same place with so
many industry colleagues.
