  • 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

    The Additive FutureIf additive manufacturing of end-use parts becomes routine, the ways we think

    about industrial production will change.

    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.

    0214AM_Feature 1.indd 4 1/16/2014 3:03:42 PM

  • AdditiveManufacturingInsight.com February 2014 5

    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.

    0214AM_Feature 1.indd 5 1/16/2014 3:03:56 PM

  • 6 AM Supplement

    F E A T U R E

    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.

    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.

    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.

    technology to quickly produce accurate parts from

    STL fles, regardless of geometric complexity.

    According to the company, the surface quality of

    the printed parts shows no signs of stairstepping

    on the inner and outer surfaces.

    The machine had been part of the companys

    Perfactory family of 3D printers that use digital

    light processing (DLP) technology. The new 3SP

    approach, which allows for larger build sizes,

    employs a multi-cavity laser diode with an orthog-

    onal mirror spinning at 20,000 rpm. It can be

    used to produce everything from concept models

    to functional parts with minimal material waste.

  • An Outlook for Additive in 2014:

    A Participants Perspective

    AdditiveManufacturingInsight.com February 2014 15

    By Tim Shinbara, Technology Director, AMTTe Association For Manufacturing Technology

    [email protected]

    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!
