Henry Ford established the model for the mass-manufacturing era of the Industrial Revolution when he created the assembly line. The assembly line promised to make products more affordable by producing many copies of identical parts. Most everything consumers buy today is produced in this manner, using large factories with lots of expensive machines and people to run them.
Products made in this manner are distributed to you through an enormously complicated global supply chain created to distribute the produced goods to far-away consumers. Global mass-manufacturing factories are spread across Asia, sending a never-ending stream of giant container ships to North American and European consumer markets. This complicated infrastructure stemmed from businesses chasing lower operating and labor costs, to bring products to you.
Additive Fabrication or, as it has become more affectionately known by the public, 3D printing, recreates an object layer-by-layer. Using a 3-dimensional digital model (CAD model) as the “blueprint,” successive layers of material are precisely deposited by a computer controlled “printer”. The result is a precise “copy” of the object.
Today’s 3D Printing technologies make use of a wide variety of materials including plastics, metals, ceramics and even biological materials. Some companies are experimenting with composite materials such as combining plastic and cellulose for a wood-like result. By using multiple print heads, different materials can be deposited at different stages, changing the characteristics of the object.
Research about 3D Printing at major universities and private companies focuses primarily on materials. Attempts to print virtually everything are under way, including food products like chocolate or sugar.
Although much hyped, 3D Printing has the potential to create the “perfect storm” for manufacturing. What used to require a highly skilled machinist with a deep background in many complex methods and techniques has been replaced by a computer controlled machine.
Following the basic tenet of the Industrial Revolution, removing the skilled labor needed to operate the machine to produce one-at-a-time items, removes much of the barrier to produce that item at affordable price points.
Often, a machinist cannot complete a part that has complex geometry without manipulating the object – such as flipping the part or object over to machine the other side. 3D Printing eliminates this burden because it removes the penalties of the complexity of a part by creating an object layer by layer.
3D Printers allow working assemblies to be printed with built-in hinges and other features. Parts can be combined in ways that traditional machining cannot accomplish, reducing part count in an assembled product.
Consider the example of a ship in a bottle: A 3D Printer can build this easily whereas a traditional machine cannot.
3D Printing is an efficient manufacturing process. In contrast, traditional manufacturing is not. For example, machining / milling uses blocks of metal that will be machined; removing large portions of the block result in the desired part. An analogy to this would be how a sculptor chips away marble to create a statue. The chips, which also took energy to form, become scrap.
In this example, the scrap metal must be shipped back, re-smelted, and shipped out again, repeating the cycle.
In contrast, 3D Printing adds material, building-up the part layer by layer. Not only does this save material, but it also saves energy because the machine only uses the energy necessary to form the part, nothing more.

Suppose that a set of presentations and reports needed to be delivered to multiple locations around the country. By sending the electronic files to a service like Office Depot®, FedEx Office®, or Staples®, exact duplicates of the documents, including color, number of pages, binding methods, etc., are produced and delivered. In the same way, sending the electronic files for an object will result in the identical part or product being made, regardless of printer location. Note that Staples® has announced that it will begin a project to add 3D Printing services to its stores5.
3D Printing is arguably one of the least promoted revolutionary technologies of all time. After 3D Printing was invented in the early 1980’s, it was adopted by the aerospace industry to create prototypes. The fledgling industry became known as Rapid Prototyping due to its speed and ease of use. Later, the technology was adopted to create cast titanium parts for fighter jets including the FA-18 Super Hornet and later the F22 Raptor.
While first coined in the 1990’s, the term “3D Printing” was not widely used until around 2008, as marketing and the public began to embrace the technology. Other related terms used to describe the technology include:
• Direct Digital Manufacturing• Additive Manufacturing• Additive Free-form Fabrication• Solid Freeform Fabrication• Rapid Prototyping• Layered manufacturing
By the 2000’s, the technology had expanded well past prototyping parts. Research on the technology began to explore “Bio-Printing,” 3D Printing of biological materials such as blood vessels and experimental human organ components. This technology is still in early stages and most likely years from FDA approval in the United States. Blood vessels, orthodontic implants, bone replacements, and other simpler structures are becoming more common in 3D Printing. To date, there is at least one well documented organ implantation.
Just as in the computer revolution, equipment that used to cost hundreds of thousands of dollars and could only be afforded by large organizations has evolved into an ecosystem ranging from the industrial grade high end all the way down to consumer-grade desktop models costing a few hundred dollars. Analogous to higher dots-per-inch in ink or toner printers, the more expensive 3D Printers will create objects with higher resolution, often with multiple or difficult to use materials.
Cheaper 3D Printers will generally create objects with rougher edges and use cheaper raw materials.
In addition to the uses described above, the technology of 3D Printing is now used to create everything from custom prosthetic limbs12 to automobile components to aerial drones13 to custom gold and silver jewelry.
The US Army is testing 3D Printers14,15,16 with the idea to construct spare parts and components near the front lines, reducing the supply chain from weeks or even months, to days or hours.
Manufacturers around the globe utilize 3D Printing and related equipment to produce everything from oil field parts to jet engine components to an ever-expanding array of custom devices and components.
Imagine that an Army tank breaks down and the nearest replacement part is misfiled at a supply depot, located somewhere in an endless sea of shipping containers. The next closest replacement part is thousands of miles away.
A 3D Manufacturing network could analyze the part, its destination, materials, and other factors required to produce the part and find an appropriate 3D Printing facility in a nearby NATO country and deliver it within a day. This is Edge Manufacturing.
This particular solution is already commercially available through software created by Kraftwurx parent company Digital Reality. That software, dubbed Digital Factory™ is currently being used for distributed Edge Manufacturing of consumer goods.
"With the right systems engineering, the remaining barriers for adoption can be removed so that out-of-stock parts can be deployed to units in the field well ahead of the current
supply chain. It will make it easier for military units to accomplish their missions. For fiscal year 2011, the
Operation & Maintenance portion of the DoD's total budget request comprises $283.1 billion. If these costs could be
reduced by one-tenth of one percent, that would account for $283 million in savings. "
In recent years, the technology has found a home in the hobby market. These less capable but intriguing consumer-grade and DIY 3D Printers retail for several hundred to a few thousand dollars.
The consumer grade equipment has garnered much press coverage and a cottage industry of artisan created figurines, toys, jewelry and art. Leading the pack of the consumer 3D Printer hardware vendors is Makerbot, with competitors including 3D Systems’s low-end Cube, Solidoodle, uPrint, and many more.
These consumer grade machines have limited capabilities and are considered hobby grade equipment. However, the quality difference between the low cost machines and the high cost machines is narrowing. Although the consumer market is the hottest segment seeing growth, it is by far substantially lower in total revenue and accounts for a small fraction of the total industry, relegating it to hobbyist use.
Digital Reality, the parent company to Kraftwurx, first demonstrated their business model in 2006.
The company has patents and patents pending branded as Digital Factory™, which is designed to provide sales, manufacturing, and distribution for 3D Printing.
This Edge Manufacturing Platform as a Service (PaaS) provides the infrastructure necessary for any company wishing to take advantage of 3D Printing for their own business without spending the millions that some companies have spent to build their own platform. The system can be white labeled, so brands can use it as their own.
Kraftwurx provides its patented1 Edge Manufacturing network to its customers that includes more than 110 facilities worldwide. When a customer requests that an item be manufactured, the system polls Edge Manufacturers after analyzing the part, material, and end use category. The system then routes the orders to facilities in concentric circles around the customeruntil the optimal combination of price and time-to-deliver are reached. The item may likely be manufactured in the same city as the customer because it reduces shipping costs and potential customs fees and delays.
Kraftwurx recently produced two copies of a small product. The first product was made in Houston, Texas, and the information for the second product was sent electronically to China. The product made in Houston was physically shipped to China. The product arrived 14 days later at a shipping cost of $140.00. When the box was opened, the product was broken, and the box had been labeled “opened by customs”. The second product was produced in China, very close to the destination.
It took 3 days to send, print and deliver the product. Production costs were similar but shipping was $115 cheaper. Time and money were saved, as well as a few trees as no jet fuel or cargo ships were needed to deliver the part.
The platform affords small and medium businesses a means to go to market by either investing solely in the design of a 3D model of a product, or, alternatively, outsourcing the design to a growing network of design professionals.
By offering this platform, Kraftwurx hopes to spur an industrial revolution and reshape the global economy by equipping small businesses to compete worldwide.
It is not necessary for professionals or hobbyists to buy and operate their own hardware because PaaS online services can take uploaded 3D designs and print and deliver them. These online services are offered by companies like Kraftwurx, Shapeways and Sculpteo.
To get a sense of the growth of the overall 3D Printing market, it is helpful to look at the publicly traded stocks of two of the leading industrial 3D Printing hardware manufacturers, 3D Systems and Stratasys. Also note that in the past two years, 3D Systems acquired rival Z Corp18, and Stratasys merged with Objet19. Figure 9: Growth in 3D Printing Hardware Stocks (source: Yahoo)
Edge Manufacturing is an evolution of the supply chain model, where Manufacturing-On-Demand bureaus, such as those employing 3D Printing, are called upon to manufacture an item due to their proximity to the destination / customer. Note the example of Edge Manufacturing in the Kraftwurx case study, above.
The ramifications of Edge Manufacturing are enormous. It will affect the global economy in ways that governments cannot yet fully understand.
The design for an item originates in Texas and is showcased on the internet. A customer in Australia browses and buys the product. While the design for the item is in the USA, the item is Edge Manufactured in Australia, so there are no USA sales taxes, international shipping, or import/customs duties.
Suddenly, the US company is competitive in Australia.
While consumers are experimenting with entry-level hardware, the industrial applications are mature. In the US and Europe, many 3D printing bureaus have been operating the technology for as long as 20 years. Most are owned or operated by employees of the long forgotten DTM Corporation20, now known as 3D Systems. Many 3D Printing bureaus provide the technology as a service to clients who use it for their own competitive and speed to market advantage.

When you consider that “objects” are another form of “content” – something to be used and consumed, the questions of copyright and trademark of the digital blueprint are sure to arise.
If a digital blueprint is made of an object,
Who controls that design?
Who profits from it?
If a ‘knock-off’ digital blueprint is made – how do brands prevent copies being 3D Printed that they don’t benefit from or control?
Who decides if a 3rd-party digital blueprint is an illegal copy or homage?
The traditional manufacturing cycle adds a significant amount of time to the equation, allowing some policing. However, once a brand creates a 3D digital blueprint today, it can be made, well… today. While this opens the door to new DRM challenges, it also changes the life cycle of products.
Now brands can potentially create new designs all the time, tying in to current events, trends and fashions on a global daily basis – macro – and also on a micro-geo scale, targeting specific product designs and customizations for micro-targeted campaigns. This can be done without inventory, and without months or year-long manufacturing and transoceanic shipping and national warehousing and distribution cycle.
When consumers are given the ability to personalize products themselves, more product diversity and a larger selection of products to choose from emerges, even with branding. Consumers suddenly drive their own designs and create new trends.
If brands cannot ultimately turn these new capabilities to their advantage against copyright violators, then perhaps these brands are destined for the scrapheap of obsolescence along with buggy whips and VCRs.
3D Printing is the first step toward a major shift in society. Companies like Nanorex have created Computer software called Nano Engineer™, which allows for precise control of building objects at the atomic level. The control of materials at this scale sets the stage for something right out of Star Trek! Illustration: Molecular level fabrication
Scientists in the Joint Quantum Institute (JQI) at the University of Maryland and the University of Michigan have announced they have successfully teleported light. The next step is to teleport entire atoms…eventually! The 3D Printer may become the replicator from Star Trek, producing items from stored patterns (computer files).
Eventually, you may very well be able to print anything you want at home. What will become of a society when we no longer need factories and employees to create the things we need and want?
