3D printing (3DP) is a classic disruptive technology that is likely to have a huge and widespread impact on the world.
This revolutionary technology is likely to dramatically change business models, shift production location, shrink supply
chains, and alter the global economic order, potentially degrading the importance of the Asian export manufacturing
platforms and revitalizing the US innovation engine and the US economy. In the process, 3DP will change the global
operating environmentfor policy makers as well as business and labor. 3DP is already a proven general purposetech-
nology that is being used for an enormous range of applications, such as fabricating spare and new parts for planes,
trains and automobiles and thousands of items in between. It has huge environmental benets, including substantial
reduction in resources consumed in production, manufacturing products only on demand, and just in time production
of goods at or near where they are consumed, greatly reducing the carbon footprint of goods produced and shipped
thousands of miles to consumers.
Policy Implications
Policy makers need to embrace this new technology and prepare for its disruptive impact on the economy, labor,
the global economy and geopolitics, security, and the military. They need to recognize that international competi-
tion in 3DP development and use is intensifying and will be a key element of economic competitiveness in the
Governments need to focus resources on advancing the technology and its utilization by their businesses and the
government itself, especially the military and space programs.
Policy makers need to anticipate and prepare for the downsidesof 3DP, ranging from intellectual property theft
and protection to security concerns about printing of guns, improvised explosive devices (IEDs), and other destruc-
tive devices.
Governments, especially in the developing world, need to capitalize on 3DP to leapfrogdevelopment stages and
to create local enterprises to manufacture goods, including from local materials, to satisfy and expand local mar-
kets, provide employment, and build national economies.
Governments should seize the opportunity of 3DP to reduce carbon emissions and enhance sustainability through
reduced transport of goods and far more productive use of raw materials.
In his 2013 State of the Union address, US president Ba-
rack Obama declared, 3D printinghas the potential to
revolutionize the way we make almost everything.Presi-
dent Obama is right: 3DP, formally known as Additive
is likely to upend the last two centuries
of approaches to design and manufacturing with pro-
found geopolitical, economic, social, demographic, envi-
ronmental, and national security implications that will
unfold over the coming two decades and beyond.
US is especially poised to take advantage of this new
technology, but it will likely provide an opportunity for
all who seize it.
The Economist has hailed 3DP as the basis of a third
industrial revolution.
This new industrial revolution is
likely to dramatically change business models, shift
production location, shrink supply chains, and alter the
global economic order, potentially degrading the impor-
tance of the Asian manufacturing platform and revitaliz-
ing the US innovation engine and the US economy. In
the process, 3DP will change the global operating envi-
ronmentfor policy makers. It especially has the potential
to transform operations for the military, from printing
spare parts and food on ships and at forward bases to
redesigning weapons and military equipment and the
business model for purchasing and maintaining those

such as fabricating spare and new parts for planes, trains
and automobiles and thousands of items in between.
Future applications that are under development range
from printing human organs and food to printing airplane
wings and large structures, including houses and large
buildings and bases on the moon and Mars. NASA views
3DP as an essential part of its space exploration plans, with
3D printers replicating themselves and making spare parts
as well as large structures in space.
And, of course, 3DP
has recently attracted attention of the US Congress and
the public with reports that people have printed guns and
high-capacity magazines for assault weapons.
Overall, 3DP is a classic disruptive technology
that is
likely to have a huge and widespread impact on the
world. 3DP machines vary widely in size, resolution,
materials used, cost, and applications. Moreover, 3DP will
impact different economic and manufacturing sectors in
different ways and at different rates. While some skeptics
maintain that 3DP is overhyped, General Electrics CEO
Jeffrey Immelt commented at a February 2013 confer-
ence in Washington that 3DP is worth my time, atten-
tion, money, and effort.
It is not too risky to project the
continued growth in the manufacturing revolution that
has been sparked by 3DP. Since 3DP has many inherent
advantages over other manufacturing technologies, any
other technology that could theoretically replace 3DP
would likely go in the same disruptive direction and just
do the job better and cheaper.
3DPs impact will be even greater as the technology
matures and is ever more widely used. For policy makers,
3DP is transforming their world today and promises to
have a far greater impact in the future, posing dangers,
opportunities, and overall a changing foreign policy and
national security landscape. This new technology is also
being developed in a new era in which governments do
not control and are often not the key innovators in many
new critical technologies. 3DP is the poster child for a
new, strategically important technology that is not only
out of the control of governments but is being rapidly
developed from the bottom upby tens of thousands of
do-it-yourself (DIY) hobbyists as well as from the top
downby businesses, universities, and government-spon-
sored research. The 3DP genie is already out of the bot-
tle. The challenge for the US and other countries is to
capitalize on the huge potential economic, environmen-
tal and social benets of this technology while hedging
against potential security risks created by the new capa-
bilities the technology is rapidly generating.
A third industrial revolution?
3DP offers a number of structural benets over tradi-
tional manufacturing:
Increased product design freedom: traditionally, prod-
ucts designs are constrained by the limitations of the
machines that will produce them. By contrast, 3DP
processes allow designers to selectively place material
only where it is needed;
No cost for complexity: in traditional manufacturing,
the more complicated a product, the more expensive
it is to manufacture if it is even possible to make it
at all. By contrast, 3DP is a single toolprocess no
matter the desired geometry, there is no need to
change any aspect of the process;
On demand production in batches of one: a given
manufacturing facility is capable of printing a huge
range of types of products without retooling and
each printing run can be customized without addi-
tional cost. Moreover, products can be printed on
demand without the need to build-up inventories of
products and spare parts.
From mass production to mass customization: Since
printing one-of-a-kind products is no more costly than
mass producing the same object, 3DP technology
enables the design and efcient manufacture of per-
sonalized products. This unique capability of 3DP is
driving a transition from mass production to mass cus-
Simplication of manufacturing process: Since 3DP
creates physical products directly from a standardized
digital le, these computer-controlled processes
require a low level of operator expertise and reduce
the amount of human interaction needed to create an
From making prototypes to manufacturing nished
products: Initially, 3DP was referred to as rapid proto-
typingand was primarily used to quickly fabricate
conceptual models of new products for form and t
evaluation. 3DP technologiesuse has evolved from
solely creating prototypes to fabricating parts for func-
tional testing, to creating tooling for injection molding
and sand casting, and nally, to directly producing
end-use parts;
Eliminating supply chains and assembly lines for many
products: The nal product or large pieces of a nal
product like a car can be produced by 3DP in one
process, unlike conventional manufacturing in which
hundreds or thousands of parts are assembled;
Designs, not products, move around the world: digital
les to be printed anywhere by any printer that can
meet the design parameters. The Internet rst elimi-
nated distance as a factor in moving information
instantly across space;
Instant production on a global scale: the representa-
tion of physical artifacts with a digital le thus enables
rapid global distribution of products, thus potentially
transforming product distribution much in the same
way the MP3 did for music;
A major boost to innovation: The rise of 3DP will likely
lead to the re-invention of many old products, as well

as to extraordinary new innovations. Since 3DP pro-
cesses can print virtually anything that can be
designed on a computer thus eliminating the limita-
tions posed by machine tools, stamping and molding
engineers and designers will no longer be limited in
their designs because of previous manufacturing tech-
nologies. New hybrid materials, such as nanocompos-
ites via 3DP, are being researched to take design and
material properties manipulation even further;
Stimulation of new interest in design and engineering:
The direct relationship between the designer and the
product a relationship that has been strained by the
past 200 years of industrial production methods will
be similar to the relationship between software engi-
neers and their products. As a result, interest in engi-
neering and industrial design could be spurred, as has
happened in the eld of computer science and soft-
ware engineering over the last half century.
Reducing waste and emissions: 3DP is likely to play a
signicant role in dramatically increasing the efciency of
resource use and in lowering overall carbon emissions,
from the process of manufacturing and to delivering
products to the end user. As only the material needed
for parts is used, there is nearly zero waste. Also, printing
on demand can eliminate storage and inventory costs,
and can reduce or eliminate the use of toxic chemicals
often used in conventional manufacturing processes.
Bringing it all back home: long-term shift in
the global economy?
The widespread use of 3DP could signicantly alter the
structure of the global economy. Production and distribu-
tion of material products could begin to be de-globalized
with manufacturing of many goods closer to the point of
consumption. Manufacturing thus could be pulled away
from manufacturing platformslike China and production
brought back to the countries where the products are
consumed. This localization of production could poten-
tially reduce global economic imbalances as export coun-
triessurpluses are reduced and importing countries
reliance on imports shrink with a new form of import
substitutiontaking hold.
This shift will reduce the movement of nished goods
around the world. The decentralization of manufacturing
to potentially vast numbers of sites all over the globe also
will reduce the needed quantitative output of any one
facility and thus render less important the speed of manu-
facturing each item. Mass productionof hundreds of
thousands of a given product may be done by producing
thousands of the same product on hundreds of printers
that are near the source of demand around the world
rather than hundreds of thousands of the same item all at
one factory. This would also serve to bring supply and
demand into near perfect alignment as the products
would only be printed where and when there was specic
demand. Moreover, the same printers producing smaller
numbers of identical items can be instantly reprogrammed
to produce different products as demanded, while the
assembly line at a mass production facility would have to
be shut down and retooled to produce a different product
and the range of different products that could be pro-
duced by that assembly line would be extremely limited
compared with the capability of the local 3DP facility.
Additionally, costs could be reduced by deploying printers
and materials to make a wide range of spare parts, rather
than keeping all the possible spares at or near where they
might be needed. This will lower the cost and eliminate
the long delays, sometimes extending to many months, in
acquiring necessary spare parts. The Defense Advanced
Research Projects Agency (DARPA) is working on printing
technologies especially for spare parts.
also could print spare parts from their stored computer
les rather than maintain huge stores of spare parts, many
of which may never be sold and in the meantime are
costly to maintain in inventory.
3DP will create new industries and professions. Produc-
tion of printers of all kinds and sophistication is already a
rapidly expanding industry with a growing customer
base from industrial and individual home printers to cre-
ation of manufacturing centers, printers in local stores,
and government agencies.
The shift in global manufac-
turing to 3DP processes could potentially involve trillions
of dollars in business over the coming decades, including
the value of products produced, the printers themselves,
and professional services, including product engineering
and design. The production and distribution of printer
cartridges of all sizes with a wide variety of materials is
likely to be an especially protable industry as it has
been in the 2D printing world for Hewlett-Packard and
other printer makers. Lawyers will also nd a large niche
in the industry as protection of 3DP intellectual property
will likely be a litigious challenge as designs for products
potentially can be widely disseminated and identical
products produced by compatible printers potentially
replicating the problem with software piracy.
The reduced need for labor in manufacturing could be
politically destabilizing in some economies that rely on
traditional manufacturing for a large percentage of their
labor force. Developing countries without large factories
employing large numbers of workers, however, may ben-
et from encouraging entrepreneurs to set up 3DP facili-
ties for design and manufacture for local consumption.
This would expand these countriesskilled labor forces
and manufacturing sectors to produce goods appropriate
for local consumers, reduce reliance on expensive
imports and reap the prots from this production.
Countries with aging societies would benet from the
ability to produce more goods with fewer people while

3D Printing: New Economic Paradigms and Strategic Shifts 3
reducing reliance on imports. This could substantially
increase overall productivity of these societies, which
would otherwise fall as the ratio of employed to retired
shifted toward fewer workers to support the growing
proportion of the population that is elderly and retired.
3DP printed medical equipment and bioprinted organs
and eventually targeted nano therapies could also signi-
cantly lower the cost of health care, which, along with
pensions, is expected to be a major drag on economic
growth in coming decades.
The military dimension
Potential security threats inherent with 3DP are already
evident in initial DIY successes in printing guns and high-
capacity magazines for assault weapons. No doubt terror-
ists will nd other uses for 3DP besides reducing their
reliance on supply chains for weapons. IEDs for example,
could be more easily disguised as ordinary civilian items.
There seems to be little governments can or should
do to stop the development of 3DP technology. They will
have to hedge against possible as well as actual threats
posed by this technology, which, fortunately so far do
not appear to include making new types of lethal equip-
ment but only enhancing the ability to elude controls
and detection in production of already existing types of
weapons. In the long run, however, there could be new
classes of weapons developed with 3DP.
The geo-economic impact of 3DP could affect the mis-
sion of the US military. A decline of mass production of
products on assembly lines at the end of long and com-
plex supply chains could lead to a peaking and gradual
reduction of global shipping of nished goods. This
could reduce the magnitude of the challenge of protect-
ing sea lanes with naval forces. Presumably raw materials
will continue to move around the planet by ship but the
quantity of shipping would likely be sharply reduced.
Increased resource productivity through 3DP could also
lower quantitative demand for natural resources and thus
reduce the likelihood of resource conict. The economic
and environmental relief offered by 3DP could include
easing demand for livestock through 3D bioprinting
meat, poultry and sh over the next two decades as the
growing middle class seeks to literally move up the food
3DP will not only change the national security environ-
ment for the military but also the way it operates. The
US military is already beneting from 3DP medical
advances from printing skin and prosthetics and is likely
to help spur further development of the technology that
could enhance the survival and rehabilitation of
wounded or injured military personnel. 3DP will also play
an increasingly important role manufacturing spare parts,
especially on ships and at forward bases, greatly reduc-
ing repair time and cost. The military could benet
substantially in the future from requiring defense con-
tractors to provide the Defense Department the intellec-
tual property and the computer les for most if not all
parts of every weapons system so the military has the
resources and rights to produce spare parts, which would
not only speed repairs but provide huge savings in main-
tenance costs over the lifetime of weapons systems and
other equipment. In the longer term, 3DP provides the
opportunity to substantially redesign weapons systems
themselves as well as the individual parts of weapons.
These redesigns could reduce the cost, weight and com-
plexity of systems while increasing their capabilities and
Many of these capabilities that benet the military will
be critically important for NASA for human exploration of
space. NASA has already commissioned the development
of 3DP for the International Space Station (ISS), especially
for printing spare parts. Made-In-Space, a Silicon Valley
startup, has built printers that have passed all NASA tests
for certication. Its rst 3D printer likely will be launched
to the ISS in mid-2014. NASA has also commissioned
development of 3D printers for food and for building
structures on the Moon.
Conclusions: the world forever changed?
The pace of development and implementation of 3DP is,
of course, uncertain and likely to vary widely for different
types of manufactured products. Many consumer prod-
ucts may be cheaper to mass produce by traditional
methods and shipped to points of consumption for a
long time. Nevertheless, there will likely be tipping points
in various elds of production at which it becomes nec-
essary for manufacturers of a given type of product to
change to the new process or lose their competitive
edge and risk extinction. This will likely be an uneven
process and could take many years longer in some areas
than in others.
The impact of 3DP on manufacturing, the environ-
ment, the global economy and geopolitics is likely to
occur gradually over several decades but the cumulative
impact is likely to be disruptive and revolutionary. This
has been the case with the personal computers, the In-
ternet, and now mobile computing. Foreseeing the spe-
cic developmental paths and timetables as well as the
economic, social, political and security impact and impli-
cations of these technologies is not possible. Virtually no
one foresaw Google, Facebook, or the iPhone even a
decade before they were created. But analysts did fore-
cast broad, revolutionary implications of the Internet. So,
too, can it be foreseen that 3DP will revolutionize the
way we make almost everythingwith huge implications
for society, even if the timing and shape of this technol-
ogys strategic impact are not completely discernable at
this stage in its development.

The impact of 3DP could go beyond transforming the
manufacturing process and rebalancing the global econ-
omy, especially if it contributes to changing the trajecto-
ries of some of the most worrisome trends in
environmental degradation, resource scarcity and climate
change. 3DPs benets toward protecting the environ-
ment and developing a sustainable global economy
could be even more signicant than its effects on the
global economy. The national security implications of
3DP thus extend far beyond the threats of printing guns
and IEDs and the benets of reducing military equipment
costs and procurement time for spare parts. 3DP can
help create a safer world in which national security plan-
ners face less poverty, political instability and military
conict by reducing the environmental impact of human
activity, from climate change to resource depletion, while
improving the lives of billions of people.

more generic term denoting the opposite of subtractive manu-
facturing. Since 3DP has become the most widely used term in
the media for the 3DP process, this paper uses the terms 3DP
instead of Additive Manufacturing. There are other manufactur-
ing processes such as stamping, casting, and injection mold-
ing that are not subtractive, but are for mass production of
identical products made from one material such as plastic for
toys or steel for bolts.

maps, in which 3D terrain is approximated by stacking 2D lay-
ers. 3DP technology rst emerged in 1977, when Swainson sug-
gested a method of creating 3D objects directly by using two
electromagnetic radiation beams and a sensitive polymer that
solidies in the presence of the beam. This method is consid-
ered to be the ancestor of modern stereolithography. Over the
past four decades, 3DP techniques have further evolved.
Researchers in the domains of mechanical engineering and
materials science have focused on improving old and creating
new techniques, as well as developing novel materials.

11. While 3DP technologies offer critical advantages over traditional
manufacturing processes, there are inherent limitations in the
processes that keep them from being a panacea for every man-
ufacturing problem. In their current embodiments, 3DP pro-
cesses are limited for mass production purposes since the build
rate is much slower than that of an injection molding machine
making large numbers of identical, single material products.
While 3DP processes will continue to increase in speed, it is
unlikely they will ever be able create parts as fast as molding
technologies. The bottleneck lies in the fundamental physics of
the processes it is not possible to scan a laser (and cure mate-
rial, and recoat each layer) at a speed comparable to that of
injection molding. This limitation is only valid for the production
of several thousand of a common part, however. Since tooling
must be created for each unique part one wishes to injection
mold, 3DP is the preferred process when custom parts, or low-
volume production runs, are needed.

... Zanetti, Cavalieri, and Pezzotta (2016) pointed at the blurred liabilities between third party service providers and design owners. Additionally, Garrett (2014) pointed at the security and military consequences of AM, such as 3D printed guns or improvised explosive devices, and argued that governments need to develop and adjust policies and laws to address these disruptive aspects AM. ...
... Moreover, Huang et al. estimated 33%-50% energy reduction during manufacturing is possible with 3DP compared to conventional methods. Furthermore, as AM enables producing goods closer to where their area of use, shorter and more straightforward supply chains will emerge requiring less amount of transportation emerge (Barz, Buer, & Haasis, 2016a) thereby reducing CO2 emissions (Garrett, 2014). Despeisse et al. (2017) posited that 3DP could support circular economies. ...
... The effect of 3DP on global value chains mainly lies in the relocation of labor from centralized manufacturing locations, such as China, closer to consumers (Garrett, 2014;Laplume et al., 2016). Moreover, Lehmhus et al. (2015) posited that AM will disrupt global supply chains and will move manufacturing back to higher-wage regions that have lost their making industry. ...
Full-text available
Additive manufacturing (AM), also called 3-dimensional printing (3DP), emerged as a disruptive technology affecting multiple organizations’ business models and supply chains and endangering incumbents’ financial health, or even rendering them obsolete. The world market for products created by AM has increased more than 25% year over year. Using Christensen’s theory of disruptive innovation as a conceptual framework, the purpose of this multiple case study was to explore the successful strategies that 4 individual managers, 1 at each of 4 different light and high-tech manufacturing companies in the Netherlands, used to adopt AM technology into their business models. Participant firms originated from 3 provinces and included a value-added logistics service provider and 3 machine shops serving various industries, including the automotive and medical sectors. Data were collected through semistructured interviews, member checking, and analysis of company documents that provided information about the adoption of 3DP into business models. Using Yin’s 5-step data analysis approach, data were compiled, disassembled, reassembled, interpreted, and concluded until 3 major themes emerged: identify business opportunities for AM technology, experiment with AM technology, and embed AM technology. Because of the design freedom the use of AM enables, in combination with its environmental efficiency, the implications for positive social change include possibilities for increasing local employment, improving the environment, and enhancing healthcare for the prosperity of local and global citizens by providing potential solutions that managers could use to deploy AM technology.
... In recent years, additive manufacturing (AM) [1] has been widely used in fabricating bone tissue engineering scaffolds. The biggest advantage of additive manufacturing is that it can produce patient-specific scaffolds with both a complex internal porous structure and a precise external architecture compared to the conventional scaffold fabrication methods [2,3]. Among AM techniques, 3D powder-based printing (3DPP) (the term "3D printing" mentioned in this paper is representative of 3D powder-based printing in particular) is the most promising technology to fabricate artificial bone implants [4][5][6], as 3D printing can be used to fabricate bone engineering scaffolds with bioceramic powders under low-temperature conditions [7,8]. ...

This paper aims to develop a reliable and effective model to investigate the behavior of micron-sized biological glue droplets impacting micron-sized bioceramic powder beds applied to the 3D printing process. It also endeavours to explore the common rules of droplet impact affected by particle size and the wettability of powder, which are supposed to provide process parameters guidance for the application of new materials in 3D printing. Firstly, based on the low impulse impact model, the simplified model was proposed. Then, the observation and simulation experiments of millimeter-scale droplet impacting were carried out under the same conditions to prove the effectiveness of the model. Furthermore, the characterization of a parametric experiment of a 3D printing practice was used to verify the significance and effectiveness of the simulation study method. Lastly, the method was performed to investigate the effect of wettability and particle size of the micron powder on the micron droplet impact. The results showed that the binder powder’s wettability and particle size could directly influence the droplet spreading behavior. The characterization results of samples printed in the simulation-predicted parameter showed that the amount of binder used could be reduced by 38.8~50.1%, while the green strength only lost 17.9~20%. The significance of this simulation method for prediction of 3D printing process parameters was verified.

A social science perspective to carbon accounting is essential for determining the appropriate allocation of reduction responsibility, and thus contributing to addressing the climate crisis. It is crucial to have a comprehensive review of the literature in this field to better understand how relevant research has evolved, and to identify gaps that future studies need to work on. Based on the bibliographic database from the Web of Science (WOS), we identified 897 publications relevant to carbon accounting in the social sciences published between 1997 and 2020. Bibliometric analysis is applied to analyze the trends and features of carbon accounting research in the social sciences. The results show that international trade has spurred considerable scholarly interest in responsibility allocation from a consumption perspective. IO (input–output) analysis that can be used to derive embodied emissions in trade has therefore become the most popular method in this domain. It is also revealed that few publications have addressed quantification of emissions at organizational level. In consideration of the importance of organizations especially corporations in emission reduction, a shift of priority to this particular area is needed for further research. Carbon label and supply chain have emerged as a subject in keywords analysis, but have not been addressed enough either. To achieve carbon neutrality, solely relying on actions at country and organizational level may not be sufficient. Greener consumption behaviors of the public and individuals could play a remarkable role. Thus, it is important to formulate a consistent framework for labeling carbon embodied in products and investigate the drivers of consumers’ low-carbon choices.

... Supply chains are transformed, as 3DP vastly shortens these interconnections by creating a singular means of production (e.g., new homes). Further, 3DP creates the conditions for an intensification of local manufacturing and a repositioning of production where products are sold, as the overall percentage of labour costs in manufacturing is minimised (Garrett, 2014). Taken in combination with digital control, supply chains can be uploaded in online platforms (e.g., Amazon) and hence become more flexible and on demand; subsequently, pre-chains will move to these digital processing of information, and the need for physical pre-chains is largely negated. ...

Global temperatures are rising. Anthropocentric climate change is upon us. Some have named this new era in which we find ourselves as the Anthropocene, wherein climate, environmental and earth conditions have been radically altered by human action. Considering these facts, that have been repeatedly proven by science (Steffen et al., 2015), the scramble to do something effective about climate change, and to adjust human inhabitation has begun in earnest. Governments have signed agreements to reduce emissions to net zero by 2050. Global agencies such as the United Nations have come up with plans to make a difference with respect to climate change in terms of planetary stewardship and global citizenship. Activists around the world have been mobilising to shift opinion and action on climate to accelerate the exit from wholesale fossil fuels. This report creates a new tactic and strategy with respect to making a difference to climate change and centralises the concept of ‘3D Printed Sustainable Houses for Education’ as a motor for change. The 3 parts of this report, though separate, are joined in the attempt to raise consciousness, insert purposeful knowledge, and evolve new pathways to tackle climate change. This report puts education in the middle of climate change action (Cole, 2021), because it is the next generation that will have to live with its consequences. Hence, given this significant rationale and motivation for students to study topics such as sustainability, experiment with new housing and lifestyle choices, and to work communally to bring down emissions, this report suggests that studying with 3D printed models and real sized houses provides an excellent basis for such activity. This report suggests that pedagogy in general should mobilise to tackle climate change, and this idea of ‘net zero-3D printing-education’ is put forward to do this. This report is future-driven, yet wholly connected to what is practical and what can be done today.

Metal alloy additive manufacturing (AM) has gained wide industrial interest in the past decade due to its capability to efficiently deliver complicated mechanical parts with high quality. However, due to a lack of understanding of the fundamental correlation between the operating conditions and build quality, the exploration of the optimal operating policy of the AM process is costly and difficult. In this work, a data-driven process optimization framework has been proposed for the additive manufacturing process, integrating machine learning, finite-element method (FEM) modeling, and cloud-edge data storage/transfer optimization. A three-level hierarchy of local machines, factory clouds, and a research center is introduced with each level responsible for its dedicated tasks. In addition, to ensure the efficiency of data transfer and storage, an edge-cloud data transfer scheme is constructed, which serves as a guideline for the data flow in the AM framework. Moreover, an overview of the connections between the proposed framework and the Industry 4.0 framework is presented.

Climate ChangeFor half a century, Chinese scientists have been flocking to a spot on the eastern rim of the North China Plain, China's breadbasket, to probe pressing agricultural questions. The region just north of the Yellow River is ground zero for tackling food-security challenges such as flood control, drought, wind erosion, and soil alkalinity. To this list of concerns, researchers have now added climate change and its potential impact on grain yields.
Much work has been done in the area of micro-patterning nanoparticles toward the fabrication of polymer electronics, micro-optical components, and complex nanocomposites. Methods for micro-patterning include direct write, etching, lithography, microcontact printing, and inkjet. Quantum dots (QD) are of particular interest in microscale patterning because of their size-dependent photoluminescence, narrow band of emission, and nonlinear optical properties. A UV light, which is integrated into the print block, cures the polymer into a solid. Subsequent layers are printed on top of the previously deposited layers and cured. In this fashion, an object is built layer-by-layer. The advantage of the PolyJet process is that the individual banks of inkjet nozzles can process different materials, which allows for the creation of multi-material objects.
