Stereolithography (SLA or SL; also known as optical fabrication, photosolidification, solid free-form fabrication and solid imaging) is an additive
manufacturing or 3D printing technology used for producing models, prototypes,
patterns, and production parts.


A Wide Variety of 3D Printing Technologies are Now Used
•

Additive manufacturing or 3D printing is a process of making a three-dimensional
solid object of virtually any shape from a digital model. 3D printing is achieved using
an additive process, where successive layers of material are laid down in different
shapes. 3D printing is also considered distinct from traditional machining
techniques, which mostly rely on the removal of material by methods such as
cutting or drilling (subtractive processes).

•

A large number of additive processes are now available. They differ in the way
layers are deposited to create parts and in the materials that can be used.
• Some methods melt or soften material to produce the layers, e.g. selective
laser melting (SLM) or direct metal laser sintering (DMLS), selective laser
sintering (SLS), fused deposition modeling (FDM)
• While others cure liquid materials using different sophisticated technologies,
e.g. stereolithography (SLA).
• With laminated object manufacturing (LOM), thin layers are cut to shape and
joined together (e.g. paper, polymer, metal)
The inventor of Fused Deposition Modeling (FDM) and founder of Stratasys Inc. is S. Scott Crump who
has led the company throughout its 24-year history.

Why All the Hype
According to market research firm Gartner, the 3D printer market
will grow as much as 75% this year (2013). Most of that growth—to
the tune of $536 million— will reportedly be fueled by enterprise
customers, but consumers are also expected to spend $133 million
on 3D printers this year.
“The great transfer of wealth and jobs to the East (China) over the
past two decades may have seemed a decisive tipping point. But
this new technology will change again how the world leans.”

Why All the Hype

•

•

3D printing is an additive technique that uses a device to create
physical objects from digital models.
While the technology behind 3D printing has been around (and
commercialized) for decades, devices are only recently started to show
up on the mainstream consumer’s radar.
Every week stories appear of plans for 3D-printed modular cities, cars,
or moon bases made from the lunar dust.
Then, there are designs for the construction of utilitarian robots with
an ability to endlessly replicate themselves. These could eventually
reach giant proportions and work to construct whole cities using 3D
printing techniques.
As the technology behind 3D printing evolves and prices drop – by
2016, Gartner predicts that enterprise-class 3D printers will be
available for under $2,000 – there may be no limit to what could
feasibly be 3D printed.
Driving this market is a new generation of crowd sourced, open-source
entrepreneurs focused on businesses and enthusiast consumers, and
chasing established industrial players.

Why All the Hype - Advantages of 3D Printing
3D Printing and Additive Manufacturing technologies have the potential to
transform whole industries and completely shift entire business models.
The question is not if 3D Printing and Additive Manufacturing will effect
product development and innovation, but how and when it will happen and
whether or organizations will be ready?
There are many benefits:
•3D printing can present a lower cost of entry for a new business
•Eliminate segments of the supply chain
•Simplify R&D
•Reduce product development time
•Reduce production costs in some cases
•Reduce energy costs by 50%
•Reduce material costs by up to 90% compared to traditional manufacturing
•Reduce inventory carrying costs (even if the per-unit production cost is
higher, it will be more than offset by the elimination of shipping and of buffer
inventories)
•Eliminate the need to develop jigs, fixtures, dies, tools and other
components

3D Printing/Product Innovation is Supported by CEO Business Priorities
GEs CEO:
3D printing is “worth my time, attention, money, and
effort,” Jeffrey Immelt, chief executive of GE, said at
an Atlantic conference today on the future of
manufacturing in Washington, D.C.
Also known as “additive manufacturing,” 3D printing
involves a machine using a digital model to design a
solid, complex product from various materials, from a
simple sculpture, to a shoe, to — perhaps? — an
airplane turbine.
Immelt said he understood the difference between “a
cartoon” and an idea that’s “worth spending a lot of
time on”: and that 3D printing clearly fits in the latter
category.
“3-D printing helps you make the product from the
core up so you have less waste,” he told Greg Ip,
economics editor of The Economist. “The tool is
cheaper, the time is faster. If all I thought 3-D printing
could do was shoes, I wouldn’t be talking about it.”
GEs Point of View:
There is a lot of talk about how great 3D printing is
already, and how it is going to change the world.
Some people believe this is just all hype or a fad that is
going to end soon. While this may or bay not be true
for the home user, in industry it is a real game
changer.

Consumerization: A 3D Printer in Every Home?
•

•

Andy Bird, chairman of Walt Disney International, predicted that 3D printers will be in every home within a
decade.
"I think every home within 10 years, probably less than that, will have its own 3D printer, just as many
homes now have a 2D or laser printer," said Bird on the first day of the Abu Dhabi Media Summit, an
annual three-day event in the capital of the United Arab Emirates.
Bird said that the technology would "revolutionize" the way the world works, and the technology has
always been used in the media and entertainment industries. He added that Disney was already looking at
ways to utilize the technology in its theme parks.
In 2012, Disney World launched the "Carbon Freeze-Me" that let visitors to the Star Wars Weekends to get a
chance to try the coolest use for 3D printing technology and relive the famous carbon freezing scene from
The Empire Strikes Back. In this year's 'Star Wars' weekend Disney offered visitors the chance to put their
face on a 3D-printed Stormtrooper figurine.
"We'll be working with technology where we can easily capture the facial features of every guest... and put it
on to dolls," Bird said on the Abu Dhabi Media Summit. Disney's D-Tech Me experience helped push ordinary
girls to become princesses with help of photo cameras, 3D scanners and 3D printers. Girls can choose one of
seven different Disney Princesses including Ariel, Aurora, Belle, Cinderella, Rapunzel, Snow White and Tiana
and hair, skin and eye color of the figurine.

The Makerbot team started Thingiverse, a site for sharing useful 3D-printable designs. The site already offers tons of useful designs
for downloading and printing out on a Makerbot or other 3D printer. The designs range from a printable pair of glasses to a
printable mini Rubix cube to printable replacement parts and upgrades for the 3D printers themselves.

Costs and Business Case
Findings from a paper by a handful of intrepid engineers at Michigan Technical University
•In the study, [Associate Professor Joshua] Pearce and his team chose 20 common household items listed on
Thingiverse. Then they used Google Shopping to determine the maximum and minimum cost of buying those
20 items online, shipping charges not included.
•Next, they calculated the cost of making them with 3D printers. The conclusion: it would cost the typical
consumer from $312 to $1,944 to buy those 20 things compared to $18 to make them in a weekend. Opensource 3D printers for home use have price tags ranging from about $350 to $2,000. Making the very
conservative assumption a family would only make 20 items a year, Pearce's group calculated that the printers
would pay for themselves quickly, in a few months to a few years.
•Assuming the 25 h of necessary printing for the selected products is evenly distributed throughout the year
these savings provide a simple payback time for the RepRap in 4 months to 2 years and provide an ROI
between >200% and >40%.
•As both upgrades and the components that are most likely to wear out in the RepRap can be printed and thus
the lifetime of the distributing manufacturing can be substantially increased, the unavoidable conclusion from
this study is that the RepRap is an economically attractive investment for the average US household already.
•It appears clear that as RepRaps improve in reliability, continue to decline in cost and both the number and
assumed utility of open-source designs continues growing exponentially, open-source 3-D printers will
become a mass-market mechatronic device.

Consumerization: A 3D Printer (Personal 3D Printer) in Every
Home? There are Some Questions
Here's a bit of irony: 3D printing is suffering from an image problem
•This maker movement has been plagued by a reputation for producing plastic knickknacks via
complicated, costly machines that are really only suitable for businesses. If 3D printing wants to court
mainstream customers—and it badly does—it needs to change this image.
•With the hype and attention on consumer 3D printing ramping up, 2014 might be a make-it-or-breakit year for the industry. And that has spurred the major players—and growing competition—to focus
on driving down prices and making their machines simpler to use. Those are key steps toward boosting
mainstream appeal of 3D printing, but it will take more than that.
•Much more. Like showing people what they can do with this technology, and why they need it in their
homes.
•If there's a single issue the 3D printer needs to address, this is it: There's no way 3D printing will take
off as a consumer technology until the industry figures out how to make people want it.
•No wonder companies are marketing lower prices and simpler features on their 3D printers. XYZ
Printing, for example, homed in on the common "assembly required" aspect of 3D printers by
showcasing its fully-built, plug-and-play "da Vinci," a line of printers that "uses easy-load filament
cartridges," a booth rep said at the Consumer Electronics Show. But that's not the only reason da
Vinci's a noteworthy entry: The company will be offering it in March for the bargain price of $499.

Weapons and Sabotage:
•The first successful test of a 3-D printed gun last month sent chills down many of our spines. What’s
the use of background checks if people can simply make guns themselves with production devices in
their homes?
•But experts point out these weapons may be hard to perfect and perhaps they are not what we
should be worried about right now.
•For example, 3-D printing already allows you to fabricate new, lightweight parts for aircraft -- and that
can significantly cut fuel consumption. But it also opens the door to making counterfeit parts for
commercial or defense operations, designed for sabotage.
•And the advent of bioprinting (printing with biological materials, including cells and tissues) expands
the possibilities even further. Today, we can print ears, as Popular Science reported; in the near future,
a terrorist might be able to print ricin.
Counterfeiting:
•Copying isn’t just something that retailers have to worry about: The U.S. Defense Department has
already had problems with (normally manufactured) counterfeit parts that can compromise military
equipment and endanger soldiers, as CNN reported. There’s a fear 3-D printing could make it easier
for flawed parts to enter the supply chain, or allow other governments to replicate U.S. military
technology -- say, from a crashed drone, helicopter or plane.
•A variation of 3D printing involves chemputing which uses chemical inks to assemble a chemistry set
similar to those found in professional labs. This ability to print drugs on demand necessarily raises the
prospect that people might print out recreational drugs -- or worse. The formula for cocaine isn’t
exactly a trade secret. Nor is the formula for chlorine gas, a crude chemical weapon used by Germans
in World War I and Iraqi insurgents in the mid-2000s.
•In the past, the easiest way for a competitor to replicate your product was by reverse engineering it.
However, with 3D printing, that part or product can be replicated much faster and easily since the
need to develop jigs, fixtures, dies, tools and other components will be eliminated
By Roxanne Palmer International Business Times

Financial and Business Implications:

•By 2016, 3D printing of tissues and organs (bioprinting) will cause a global debate about
regulating the technology or banning it for both human and nonhuman use. Near Term
Flag: The U.S. Food and Drug Administration or comparable agency in a developed nation
that is charged with evaluating all medical proposals will introduce guidelines that
prohibit the bioprinting of life-saving 3D printed organs and tissues without its prior
approval by end of 2015.
•By 2018, 3D printing will result in the loss of at least $100 billion per year in intellectual
property globally. Near Term Flag: At least one major western manufacturer will claim to
have had intellectual property (IP) stolen for a mainstream product by thieves using 3D
printers who will likely reside in those same western markets rather than in Asia by 2015.
•The plummeting costs of 3D printers, scanners and 3D modeling technology, combined
with improving capabilities, makes the technology for IP theft more accessible to wouldbe criminals. Importantly, 3D printers do not have to produce a finished good in order to
enable IP theft. The ability to make a wax mold from a scanned object, for instance, can
enable the thief to produce large quantities of items that exactly replicate the original.

Gartner Reveals Top Predictions for IT Organizations and
Users for 2014 and Beyond

29


And of Course New Legal Implications Have Surfaced
Weapons and Sabotage:
•U.S. Sen. Charles E. Schumer, D-N.Y., has called for legislation banning 3-D printed guns, noting that
such weapons can bypass metal detectors. California state Sen. Leland Yee, D-8th District, has also
called for new laws. But experts point out these weapons may be hard to perfect and perhaps they are
not what we should be worried about right now.
•Yee’s team is still working on language for a legislative proposal -- one of the challenges is settling on
the precise legal term that explains the function of a 3-D printer.
•While individual politicians might say they’re focusing on the product and not on the manufacturing
device, there are some rumblings in Washington of the possibility of registering 3-D printers and
restricting the dissemination of blueprints.
•California legislators are concerned about “ghost guns” firearms that people build and assemble that
do not come with a serial number on the firearm and undergo a background check. (Senate Bill 808 is
aimed at correcting this situation.
Counterfeiting:
•Virginia Tech researcher Thomas A. Campbell told International Business Times. “The same thing
occurred with the Internet; the same thing occurred with cell phones.”
•Part of Campbell’s job is to think about the fast-evolving nature of 3-D printing, particularly in the
field of counterfeiting.
•“It’s really hard to grasp what one or two regulations are needed,” 3-D printing security analyst
McNulty said. “My biggest concern would be if we used these concerns as justification not to invest
in the continued exploration and development of this technology.”
•“The whole idea of regulating 3-D printing is enormously difficult to conceptualize,” Darren S. Cahr, an
intellectual-property attorney with Drinker Biddle & Reath LLP, said in a phone interview. “Not to say
that people haven’t tried. But people have been using injection molding, or tools and dyes, to make
things for decades -- and centuries in some cases. It’s just not feasible to try and regulate everyone
out there who can use a manufacturing process to make something.”

•

Reconstructing fossils in paleontology,
Replicating ancient and priceless artifacts in archaeology,
Reconstructing bones and body parts in forensic pathology,
Reconstructing heavily damaged evidence acquired from crime scene investigations.
Used for building construction.
Possible use in tissue engineering applications in which organs and body parts are built using
inkjet techniques.
Possible to use 3D printing techniques to create chemical compounds,
China has committed almost $500 million towards the establishment of 10 national 3-D
printing development institutes
• In 2013, Chinese scientists began printing ears, livers and kidneys, with living tissue.
Researchers in China have been able to successfully print human organs using
specialized 3D bio printers that use living cells instead of plastic.
One of these advances is the use of 3D printers is to produce casts that are created to mimic
the bones that they are supporting. These custom-fitted casts are open, which allow the
wearer to scratch any itches and also wash the damaged area
In 2012, the U.S.-based group Defense Distributed disclosed plans to "[design] a working
plastic gun that could be downloaded and reproduced by anybody with a 3D printer.“
Defense Distributed has also designed a 3D printable AR-15 type rifle lower receiver (capable
of lasting more than 650 rounds) and a 30 round M16 magazine. In May 2013, the United
States Department of State demanded that they remove the instructions from their website.

Concluding Observations…open to debate
Applications of the 3D Printing technology that make sense now:

•Mass customization of complex metal parts (applications where geometry and material characteristics
are demanding) as an example: 3D Printing has a definite role in some manufacturing:
•

•

34

According to a GE Report, “Next-Gen Jet Engines with 3D Printed Parts,” the new fleet of
engines will require more than 85,000 fuel nozzles and prompted research into how the
strongest and most cost effective nozzles could be manufactured. Previously, GE’s fuel nozzles
contained 20 different parts and required frequent maintenance and replacement.
After careful analysis, it was determined that an investment in “additive manufacturing” or 3D
printing technology would allow each fuel nozzle to be manufactured as one metal piece
through layering of material that is typical of 3D printing. The end product is 3D printed nozzles
that are stronger and lighter than those made using the old assembly method. The fuel nozzles
are also capable of withstanding extreme temperatures of up to 2,400° inside the jet engine
which tended to soften parts made using the old method.

•Return to US of some of the Chinese manufacturing where multiple 3D printers can process the required
volume
•Replacement of low volume - low complexity order on demand parts in both metal and plastic material
compositions for both the consumer and business marketplaces
•Replacement of parts for maintenance and repair in the appliance and auto parts after markets
•Design verification and end product design reviews for obtaining the Voice of the Customer (like
prototypes of the plastic vacuum cleaners and other household appliances, apparel accessories and
shoes, mobile devices, hand held computer products, communication and networking devices, etc.)
•In some cases the production manufacturing of the above items
•R&D of bio medical replacement parts and tissues
•Transmission of critical parts to hard to get to locations (like the International Space Station or ocean
vessels)
•Low volume manufacturing for various forms of arts and crafts (3D Printed objects sale and exchange
fairs) and Jewelry of a large variety of shapes and materials

Stereolithography (SLA) is often considered the pioneer of the Rapid
Prototyping industry, with the first commercial system introduced in 1988
by 3D Systems. The system consists of an Ultra-Violet Laser, a vat of photocurable liquid resin, and a controlling system.
A platform is lowered into the resin (via an elevator system), such that the
surface of the platform is a layer-thickness below the surface of the resin.
The laser beam then traces the boundaries and fills in a two-dimensional
cross section of the model, solidifying the resin wherever it touches. Once
a layer is complete, the platform descends a layer thickness, resin flows
over the first layer, and the next layer is built. This process continues until
the model is complete.
Once the model is complete, the platform rises out of the vat and the
excess resin is drained. The model is then removed from the platform,
washed of excess resin, and then placed in a UV oven for a final curing. The
stereolithography model is then finished by smoothing the "stair-steps."

•Selective Laser Sintering (SLS) uses a laser to sinter powder based materials together, layerby-layer, to form a solid model. The system consists of a laser, part chamber, and control
system.
•The part chamber consists of a build platform, powder cartridge, and leveling roller. A thin
layer of build material is spread across the platform where the laser traces a twodimensional cross section of the part, sintering the material together. The platform then
descends a layer thickness and the leveling roller pushes material from the powder cartridge
across the build platform, where the next cross section is sintered to the previous. This
continues until the part is completed.
•Once the model is complete, it is removed from the part chamber and finished by removing
any loose material and smoothing the visible surfaces. (Direct Metal Laser Sintering (DMLS)
is a variation of this technology
•Fused Deposition Modeling (FDM) uses dual nozzles to trace each cross section depositing
thermoplastic material on the build platform,
•When a cross section is complete, the build platform is slightly lowered and the process
continues.
•Completed parts are removed from the chamber and support material is cleaned off
•Over a half dozen thermoplastic materials are available with varying tensile and structural
modulus and color are available

ColorJet Printing (CJP) is an additive manufacturing technology
which involves two major components – core and binder. The
Core™ material is spread in thin layers over the build platform with a
roller. After each layer is spread, color binder is selectively jetted
from inkjet print heads over the core layer, which causes the core to
solidify. The build platform lowers with every subsequent layer
which is spread and printed, resulting in a full-color threedimensional model.
Whether printed with color or in standard white, parts can be
additionally clear coated to add a hard smooth coating or wax
coated to smooth out the surface finish.
MultiJet Printing (MJP) is a new Rapid Prototyping process that
provides a quick turnaround for smooth, fully cured parts. The
process consists only of UV bulbs and photopolymer materials.
ProJet MultiJet Printing machines fully cure each layer of super fine
UV curable acrylic plastics and support materials. Support material
is easily separated from the part by a melting and washing process.
No extra finishing treatments are needed.
Finished MJP parts can readily absorb paint and can also be
machined, drilled, nickel-plated or used for direct casting patterns.

Plastic Jet Printing (PJP) is a solid-based rapid prototyping method that
extrudes material, layer-by-layer, to build a model. The system consists of a
build platform, extrusion nozzle, and control system.
The build material, a production quality thermoplastic, is melted and then
extruded through a specially designed head onto a platform to create a twodimensional cross section of the model. The cross section quickly solidifies,
and the platform descends where the next layer is extruded upon the
previous layer. This continues until the model is complete, where it is then
removed from the build chamber and cleaned for shipping.
Electron Beam Melting (EBM) is an Additive Manufacturing method for 3D
Printing of parts in real titanium alloys. The material is super-strong and the
parts can be used for high-demanding applications like race cars, space ships,
aircrafts or human implants. The EBM process takes place in vacuum and
NASA even look at it as a candidate for manufacturing in space!
With EBM, material in wire form is fed into a molten pool created by an
electron beam; the deposition mechanism creating the melt pool and feeding
the wire is then guided by a computer to move about on an also nonstationary build platform. The deposition mechanism deposits the material
just where it is needed to form a layer of the object. Repeating this process
builds up the object one layer at a time. Finally, after the object is built, post
processing usually requires machining to remove excess material. The
process currently has one of the largest build capacities of any 3D printing
process.

Block Diagram Process Overview
• DLP 3-D Printer solutions process successive layers of material to produce a 3-D physical objects. The object is
specified by a 3D Computer Aided Design (CAD) model. 3D printer software transforms the virtual 3D model into a
series of layers suitable for printing the object.
• It is often used to quickly create detailed prototypes. With this technology, printing parts of a material can be done
in a single process flow. 3D printers are becoming more affordable for medium and small scale businesses in which
rapid prototyping is brought all the way into the office, no longer requiring manufacturing floor space.
• Two common methods for 3D printing are digital exposure and laser sintering. The high level principles for
incorporating DLP technology into a 3D printing solution can be applied to both methods, but digital exposure is
represented in the system block diagram.
• For the digital exposure technique, the 3D object is constructed by laying down successive thin horizontal crosssections or layers of an ultraviolet (UV) curable liquid photopolymer resin. For each layer, the UV light image from
the DLP® Digital Micromirror Device (DMD) creates a pattern which hardens the polymer resin where it is exposed to
the light.
• The cross-section pattern is produced by the individual mirrors that correspond to each pixel on the current layer.
This pattern projects through an imaging lens onto the surface of the UV curable liquid photopolymer resin, curing
or hardening it where the pixels are on. As depicted in the diagram, one resin is the build material and the second is
material to support overhanging features and thin vertical walls during construction. The support material is later
removed by heat or dissolved with a solvent or water.
• These layers fuse automatically and the process repeats one layer at a time until the model is built. Cure rates are
possible under 0.2 seconds per layer. Layer thickness typically ranges from 1um to 250um based upon the resin and
wavelength of the UV light used. More detailed images require more discrete cross-sections to assume the
continuous smooth surface effect of the resulting object.
• The diagram shows a DLP chipset, which includes the DMD, and a DMD Controller chip, plus a DMD Analog Control
chip (depending on the specific DLP chipset). DLP chipsets are available with different DMD sizes, pixel pitches,
resolutions, and other specifications. DLP also offers devices targeted for use with UV light. The best choice for a DLP
chipset may depend on the desired object feature size, patterning speed and necessary wavelengths to cure the
resin.
• The CAD model is produced by software running on a PC. The system control and signal processing is accomplished
by the Embedded Processor (Such as TI OMAP®). Power is provided by TI Power devices. The details of the optical
layout and components are not shown in the diagram. The diagram is intended to convey as simply as possible the
overall functionality of a DLP-based 3D Printer application. An actual product will require additional optical
components and optical design in order to achieve full functionality.

4) Eyes on the Future
There are several startups — some still looking for funding — that aim to bring fashion into the twenty-first
century using 3D printing. These companies focus on mass manufacturing highly customizable products, like
eyeglasses and iPhone cases, with 3D printing technology.
Make Eyewear is experimenting with 3D printed glasses. The company's frames are printed with a
lightweight, flexible nylon that can be fitted with prescription or tinted lenses.
And Protos, another 3D eyewear startup, is currently developing a way to offer customers a simple way to
design their own 3D-printable frames.
5) Spuni
No one has ever been accused of being born with a 3D-printed spoon in their mouth — until now. Spuni, the
ergonomically designed baby spoon, was created by two MIT grads fed up with the mess that accompanies
feeding a baby from a regular baby spoon.
In order to make their Spuni dreams come true, the product's creators used 3D printing to design and
perfect a prototype that they could test on hungry babies.
Clearly the prototype worked well, because Spuni has since raised over $35,000 with its Indiegogo campaign
and its first products are being shipped to customers this month.
6) Tecnologia Humana 3D, and Fasotec
But parents don't have to wait until baby starts eating solid food to take advantage of 3D printing
technology. Tecnologia Humana 3D, a Brazilian company specializing in customizable 3D-printed orthotics,
offers expecting mothers and fathers a three dimensional look at their beloved fetus in utero.
That's right — a 3D-printed ultrasound. The Japanese company Fasotec offers a similar product for
expecting parents at a pregnancy clinic in Tokyo. For just over $1,000, customers can take home a 3D
printed, key-chain sized fetus of their very own.

7) Organovo
Based in San Diego, Organovo is a biotech startup focused on the development of 3D printed biological
materials, particularly human tissues. Since the company's founding in 2007, it has pioneered research in 3D
bioprinting, creating synthetic tissues that function just like real human tissues.
Materials printed at Organovo help researchers study diseases and allow them to test the effects of drugs on
human tissue without putting anyone at risk. The company is also working on printing materials — like liver
tissue — that can be used for medical implants or replacements.
8) The Dreambox
If you need something 3D-printed in a hurry, head to Dreambox. Developed by undergrads at the University
of California Berkeley, Dreambox is a 3D printing vending machine that can create whatever object you tell
it to in minutes.
The Dreambox is currently housed only on the UC Berkeley campus, but its developers have already
received funding for their startup and are on their way toward making mobile 3D printing a reality for all.
9) Thinker Thing
Imagine if you could create an object just by thinking about it. Chilean-based startup Thinker Thing wants
you to be able to do just that.
This innovative company aims to connect the latest neuro technological equipment- like brain-computer
interfaces- with 3D printing technology. In other words, they're creating software that makes it possible for
someone wearing an electroencephalography (EEG) headset to picture an object in his or her mind and
have that object printed in 3D.

GEs Commitment is a Signal for the Industrial Marketplace
•

GE’s been utilizing 3D printing for quite awhile now, including the use of their proprietary laser cladding
technology, which can print directly onto objects, mainly for repairs.
While additive manufacturing at GE is mostly practiced for research, they plan to use the technology
increasingly as a method of production. The aerospace division is the furthest towards reaching this goal
with the LEAP jet engine, as covered by 3DPI, that “will have a total of 16 3D printed fuel nozzles in it
and be used on the Airbus A320 NEO, 737 Max and COMAC C919”.
Singh wishes to see the following advancements in GE’s AM Lab: “closed loop control, published
databases of materials and material characteristics, systems to inspect parts, significant improvements
to post processing, an expansion and improvement to the design tools used for 3D printing and cobalt
chrome, iconel and other materials optimized for aerospace applications.” If you read this article, you’ll
understand that the lack of closed loop control causes quality management of printed parts to take up
to 30% of the manufacturing time. It’s actually a big issue in 3D printing as a whole because, without
closed loop control, 3D printers can’t self-correct and it’s difficult to achieve reliability and
reproducibility. If an item gets messed up during a print, it just comes out messed up and you have to
print it again.
The future of GE may include 3D printing ceramics, piezoelectrics, piezoceramics, resistors, inductors,
and capacitors. If you’re like me and didn’t know what piezoelectricity was, here’s the definition from
Wikipedia: “piezoelectricity is the electric charge that accumulates in certain solid materials (notably
crystals, certain ceramics, and biological matter such as bone, DNA and various proteins) in response to
applied mechanical stress.” The most common example is the piezoelectric crystal found in lighters. It’s
what allows for that little spark of electricity that ignites the flame when you press down the button
onto that long grill lighter you use for starting your BBQ.
The benefits Singh sees with 3D printing at GE is that it streamlines the entire production process and
allows for complex shapes that can’t be manufactured by traditional means, saying that his designers
“‘are spoiled...with [being able to make] hundreds of designs’ and that they ‘change designs weekly.’”
From interview with the manager of the GE Additive Manufacturing Lab at GE Global
Research, Prabhjot Singh.

3D Printing Could Facilitate the First of Self Replicating Machines
• A self-replicating machine would need to have the capacity to gather energy and raw materials, process
the raw materials into finished components, and then assemble them into a copy of itself. Further, for a
complete self-replication, it must, from scratch, produce its smallest parts, such as bearings, connectors
and delicate and intricate electronic components. It is unlikely that this would all be contained within a
single structure, but would rather be a group of cooperating machines or an automated factory that is
capable of manufacturing all of the machines that comprise it.
• The factory could produce mining robots to collect raw materials, construction robots to assemble new
machines, and repair robots to maintain itself against wear and tear, all without human intervention or
direction. The advantage of such a system lies in its ability to expand its own capacity rapidly and without
additional human effort. In essence, the initial investment required to construct the first self-replicating
device would have an infinitely large payoff with no additional labor cost.
• Such a machine violates no physical laws, and the basic technologies necessary for some of the more
detailed proposals and designs already exist.
• In 2005, Adrian Bowyer of the University of Bath started the RepRap Project to develop a rapid
prototyping machine which would be able to manufacture some or most of its own components,
making such machines cheap enough for people to buy and use in their homes. The project is releasing
its designs and control programs under the GNU GPL. The RepRap approach uses fused deposition
modeling to manufacture plastic components, possibly incorporating conductive pathways for circuitry.
Other components, such as steel rods, nuts and bolts, motors and separate electronic components, would
be supplied externally. In 2006 the project produced a basic functional prototype and in May 2008 the
machine succeeded in producing all of the plastic parts required to make a 'child' machine.
• Some researchers have proposed a microfactory of specialized machines that support recursion—nearly
all of the parts of all of the machines in the factory can be manufactured by the factory.

A 3D Printer that Can Print a Copy of Itself

Design for 3D Printing
Things to keep in mind when designing for 3D printing:

When you're designing a 3D model for print or video there's little need to pay any attention to reality. Most
scenes and objects will only contain the meshes that are visible, objects don't need to really connect, etc.
You can completely ignore the physical world.
As some engineers have already discovered, once you start working with 3D printers this is very different!
This mini-tutorial will cover a few common pitfalls that one engineer encountered over a few weeks.
1. Objects must be closed
3D printing companies like to call this being 'watertight'. It can sometimes be a pain to identify where this
problem occurs in your model. If you can't find it try AccuTrans - it will highlight the problem area for you.
2. Objects must be manifold
The full definition of manifold is quite mathematic. For our purposes, a mesh will become non-manifold if it
has edges that are shared between more than two faces.
3. Observe the maximum size and wall-thickness
The maximum size of your object and the minimum wall-thickness depend on the production method that
you are planning to use.
4. Correct normals
All surfaces of your model should have their normals pointing in the correct direction. When your model
contains inverted normals our printers cannot determine the inside or outside of your mesh or model.

3D Printing Model Development Software
A sampling of popular 3D printing software:
•Magic: Popular with beginners and personal use practitioners
•ReplicatorG: This Open Source software offers experimental file import capability for OBJ and Collada, two other
widely used formats, although the files are then converted to STL,
•MakerWare: supports OBJ as well as STL. You can also download 3D swiss army knife tools like MeshLab and the
free netfabb Studio Basic, which can open dozens of different file formats and export them as binary or ASCII STL
files, opening up even more models to ReplicatorG.
•Autodesk® 123D® products are useful tools for making things—for quickly giving shape to your idea, exploring it,
and most importantly, making it. The Autodesk 123D family is free* products that connect simple 3D modeling
tools together with content, community, and fabrication services, so anyone can create, explore, and make their
project. The 123D Design is used to create a digital model on the iPad, on the web, or on a desktop, and then
directly 3D print or fabricate it.
•MeshLab - Open source software for processing and editing of unstructured 3D triangular meshes. It also has an
extremely fast slide function.
•Google SketchUp plugin - A plugin script to import and export STL files for Google SketchUp. Supports both
binary and ASCII import and export.
•SLT-viewer - Display and manipulate the contents of stereolithography or STL file.
•Most major CAD design vendors have an STL file creation capability

Education and Training for 3D Printing
Learn 3D Printing Technology at a College Near You

Richard Nass, Brand Director
7/15/2013
If you were looking for confirmation that 3D printing -- sometimes used synonymously with rapid
prototyping -- is here to stay, here's further evidence: NYU now offers a course on the topic that
results in students receiving a certificate.
According to the university's course description:
•Rapid Prototyping is a certificate geared to familiarize students with digital tools and techniques
relevant to the task of visualizing and prototyping 3D designs. Focusing on products and sculpture
as the primary area of application, students will be taken through a series of hands-on class
exercises supported with specialized video tutorials in order to become comfortable with the
process of realizing their designs digitally.
•Upon completion of the course, students will know how to take a concept and execute it into a
successful 3D model using tools like Maxon's Cinema 4D, Autodesk's Mudbox, and Pixelogic's
ZBrush software. At the end of the class, students will create professional 3D product visualizations
and physical prototype models of their designs created with a 3D printer.
Some further investigation shows NYU as a pioneer in this field. A quick search showed that a few
other reputable colleges offer similar courses. Clearly, 3D printing, and the expertise that's required
to make it successful, are making inroads into the design engineering community.

•If you've got—or are thinking of getting—access to an inexpensive 3D printer such as the ones from MakerBot and
PrintrBot, there will come a time (soon!) when you'll graduate from printing other peoples' designs. There's no
doubt that you can have plenty of fun downloading and printing designs from Thingiverse, but sooner or later, the
urge to design will take over.
Whether you use a web-based modeler optimized for 3D printing (such as TinkerCAD) or a professional CAD tool,
designing for 3D printing demands expertise in everything from structural engineering to material science. You need

Open Source Impacts for 3D Printing Education

Colleges and universities are finding more and more uses
for 3-D-printing technology, which has grown in
sophistication and fallen in price in recent years. Some
proponents argue that nearly every discipline could benefit
from the ability to easily create objects from customized
designs. "We want this for humanities, for social sciences,
for bio people, for law school, so what's interesting about
3-D printing is that it touches on all these areas," says Hod
Lipson, a professor of mechanical engineering and of
computing and information science at Cornell University,
who is creating a 3-D-printing course for nonengineers.
Given those possibilities, it's every mechanical-engineering
student's dream to work with a 3-D printer, says Mr.
Ganter, of Washington. But while most major mechanicalengineering departments now have the machines, only
recently have they moved beyond those confines.
A key factor is the open-source 3-D printers, which have
made the technology affordable. Open-source enthusiasts
design small 3-D printers, usually from expired patents, and
post instructions online so others can follow their lead.
That makes it possible for do-it-yourselfers to buy the parts
and build their own printers for a price hovering in the
hundreds of dollars, rather than the thousands that off-theshelf 3-D printers cost.
In a campus setting, the cheaper printers provide the
opportunity for more students to make their own designs,
creating what Mr. Ganter calls "a paradigm shift in
education."
