In this article, we will know about the incredible rise of 3D printing in the future.
Manufacturing enterprises are faced with an increasingly demanding and challenging global environment. Today’s highly competitive marketplace demands that innovation be achieved faster and cheaper. To survive and win, manufacturers must be smarter in their delivery by making product design easier, shortening development cycles, and reducing costs. That is to build better, faster, and smarter.
As the Fourth Industrial Revolution sweeps across the globe, it is fundamentally reshaping the way in which organizations everywhere operate and their employees work and manufacturing is a prime example. The digitization at the core of this revolution—enabled and accelerated by cloud computing and related technologies such as artificial intelligence (AI), the Internet of Things, and machine learning—is empowering manufacturers to use data-driven intelligence to transform their business processes and to enrich their market offerings by combining innovative products with value-added services. To deepen customer engagements, accelerate their productivity and agility, improve safety and sustainability and reimagine how they operate and
3D Printing – The 4th Industrial Revolution?
3D printing is at a tipping point, about to go mainstream in a big way. Most executives and many engineers don’t realize it, but this technology has moved well beyond prototyping, rapid tooling, trinkets, and toys. “Additive manufacturing” is creating durable and safe products for sale to real customers in moderate to large quantities.
The beginnings of the revolution show up in a 2014 PwC survey of more than 100 manufacturing companies. At the time of the survey, 11% had already switched to volume production of 3D-printed parts or products. According to Gartner analysts, a technology is “mainstream” when it reaches an adoption level of 20%.
Among the numerous companies using 3D printing to ramp up their production are GE (jet engines, medical devices, and home appliance parts), Lockheed Martin and Boeing (aerospace and defense), Aurora Flight Sciences (unmanned aerial vehicles), Invisalign (dental devices), Google (consumer electronics), and the Dutch company LUXeXcel (lenses for light-emitting diodes, or LEDs).
Watching these developments, McKinsey recently reported that 3D printing is “ready to emerge from its niche status and become a viable alternative to conventional manufacturing processes in an increasing number of applications.”
In 2014 sales of industrial-grade 3D printers in the United States were already one-third the volume of industrial automation and robotic sales. Some projections have that figure rising to 42% by 2020.
Rise of 3D Printing In The Future Will Change The World
More companies will follow as the range of printable materials continues to expand. In addition to basic plastics and photosensitive resins, these already include ceramics, cement, glass, numerous metals, and metal alloys, and new thermoplastic composites infused with carbon nanotubes and fibers. Superior economics will eventually convince the laggards. Although the direct costs of producing goods with these new methods and materials are often higher, the
greater flexibility afforded by additive manufacturing means that total costs can be substantially lower.
With this revolutionary shift already underway, managers should now be engaging with strategic questions on three levels:
1. Sellers of tangible products should ask how their offerings could be improved, whether by themselves or by competitors. Fabricating an object layer by layer according to a digital “blueprint” downloaded to a printer allows not only limitless customization but also for designs of greater intricacy.
2. Industrial enterprises must revisit their operations. As additive manufacturing creates myriad new options for how, when, and where products and parts are fabricated, what network of supply chain assets and what mix of old and new processes will be optimal?
3. Leaders must consider the strategic implications as whole commercial ecosystems begin to form around the new realities of the rise of 3D printing in the future. Much has been made of the potential for large swaths of the manufacturing sector to atomize into an untold number of small “makers.” But that vision tends to obscure a surer and more important development: To permit the integration of activities across designers, makers, and movers of goods, digital platforms will have to be established. At first, these platforms will enable design-to-print activities and design sharing, and fast downloading, soon they will orchestrate printer operations, quality control, real-time optimization of printer networks, and capacity exchanges among other needed functions. The most successful platform providers will prosper mightily by establishing standards and providing the settings in which a complex ecosystem can coordinate responses to market demands. But every company will be affected by the rise of these platforms. There will be much jockeying among incumbents and upstarts to capture shares of the enormous value this new technology will create.
These questions add up to a substantial amount of strategic thinking, and still another remains: How fast will all this happen? For a given business, here’s how fast it can happen: The U.S. hearing aid industry converted to 100% additive manufacturing in less than 500 days, according to one industry CEO, and not one company that stuck to traditional manufacturing methods survived. Managers will need to determine whether it’s wise to wait for this fast-evolving technology to mature before making certain investments or whether the risk of waiting is too
great. Their answers will differ, but for all of them, it seems safe to say that the time for strategic thinking is now.
Additive’s Advantages From The Rise Of 3D Printing In The Future
It may be hard to imagine that this technology will displace today’s standard ways of making things in large quantities. Traditional injection-molding presses, for example, can spit out thousands of widgets an hour. By contrast, people who have watched 3D printers in action in the hobbyist market often find the layer-by-layer accretion of objects comically slow, but recent advances in technology are changing that dramatically in industrial settings.
Some may forget why standard manufacturing occurs with such impressive speed. Those widgets pour out quickly because heavy investments have been made upfront to establish the complex array of machine tools and equipment required to produce them. The first unit is extremely expensive to make, but as identical units follow, their marginal cost plummets.
Additive manufacturing doesn’t offer anything like that economy of scale. However, it avoids the downside of standard manufacturing—a lack of flexibility, because each unit is built independently, it can easily be modified to suit unique needs or, more broadly, to accommodate improvements or changing fashion and setting up the production system in the first place is much simpler, because it involves far fewer stages. That’s why 3D printing has been so valuable for producing one-offs such as prototypes and rare replacement parts. But additive manufacturing increasingly makes sense even at a higher scale. Buyers can choose from endless combinations of shapes, sizes, and colors, and this customization adds little to a manufacturer’s cost even as orders reach mass production levels.
A big part of the additive advantage is that pieces that used to be molded separately and then assembled can now be produced as one piece in a single run. A simple example is sunglasses: The 3D process allows the porosity and mixture of plastics to vary in different areas of the frame. The earpieces come out soft and flexible, while the rims holding the lenses are hard. No assembly is required.
Printing parts and products also allows them to be designed with more complex architectures, such as honeycombing within steel panels or geometries previously too fine to the mill. Complex mechanical parts—an encased set of gears, for example, can be made without assembly. Additive methods can be used to combine parts and generate far more interior detailing. That is why GE Aviation has switched to printing the fuel nozzles of certain jet engines. It expects to churn out more than 45,000 of the same design a year, so one might assume that conventional manufacturing methods would be more suitable, but printing technology allows a nozzle that used to be assembled from 20 separately cast parts to be fabricated in one piece. GE says this will cut the cost of manufacturing by 75%. Additive manufacturing can also use multiple printer jets to lay down different materials simultaneously. Thus Optomec and other companies are developing conductive materials and methods of printing micro-batteries and electronic circuits directly into or onto the surfaces of consumer electronic devices. Additional applications include medical equipment, transportation assets, aerospace components, measurement devices, telecom infrastructure, and many other “smart” things.
The enormous appeal of limiting assembly work is pushing additive manufacturing equipment to grow ever larger. At the current extreme, the U.S. Department of Defense, Lockheed Martin, Cincinnati Tool Steel, and Oak Ridge National Laboratory are partnering to develop a capability for printing most of the endo- and exoskeletons of jet fighters, including the body, wings, internal structural panels, embedded wiring and antennas, and soon the central load-bearing structure. So-called big area additive manufacturing makes such large-object fabrication possible by using a huge gantry with computerized controls to move the printers into position. When this process has been certified for use, the only assembly required will be the installation of plug-and-play electronics modules for navigation, communications, weaponry, and electronic countermeasure systems in bays created during the printing process. In Iraq and Afghanistan, the U.S. military has been using drones from Aurora Flight Sciences, which prints the entire body of these unmanned aerial vehicles—some with wingspans of 132 feet—in one build.
This brief discussion of additive manufacturing’s advantages suggests how readily companies will embrace the technology—and additional savings in inventory, shipping, and facility costs will make the case even stronger. The clear implication is that managers in companies of all kinds should be working to anticipate how their businesses will adapt on the three strategic levels mentioned above.
Product strategy is the answer to that most basic question in business, What will we sell? Companies will need to imagine how their customers could be better served in an era of additive manufacturing. What designs and features will now be possible that were not there before? What aspects can be improved because restrictions or delivery delays have been eliminated?
For example, in the aerospace and automotive industries, 3D printing will most often be used in the pursuit of performance gains. Previously, the fuel efficiency of jet fighters and vehicles could be enhanced by reducing their weight, but this frequently made them less structurally sound. The new technology allows manufacturers to hollow out a part to make it lighter and more fuel-efficient and incorporate internal structures that provide greater tensile strength, durability, and resistance to impact. And new materials that have greater heat and chemical resistance can be used in various spots in a product as needed.
Want to know how fast is the rise of 3D printing in the future coming?
In other industries, the use of additive manufacturing for more-tailored and fast-evolving products will have ramifications for how offerings are marketed. What happens to the concept of product generations—let alone the hoopla around a launch—when things can be upgraded continually during successive printings rather than in the quantum leaps required by the higher tooling costs and setup times of conventional manufacturing? Imagine a near future in which cloud-based artificial intelligence augments additive manufacturing’s ability to change or add products instantly without retooling. Real-time changes in product strategy, such as product mix and design decisions, would become possible. With such rapid adaptation, what new advantages should be core to brand promises? And how could marketing departments prevent brand drift without losing sales?
Operations strategy encompasses all the questions of how a company will buy, make, move, and sell goods. The answers will be very different with additive manufacturing. Greater operational efficiency is always a goal, but it can be achieved in many ways. Today most companies contemplating the use of the technology do a piecemeal financial analysis of targeted opportunities to swap in 3D equipment and designs where those can reduce direct costs. Much bigger gains will come when they broaden their analyses to consider the total cost of manufacturing and overhead.
How much could be saved by cutting out assembly steps? Or by slashing inventories through production only in response to actual demand? Or by selling in different ways—for example, direct to consumers via interfaces that allow them to specify any configuration? In a hybrid world of old and new manufacturing methods, producers will have many more options; they will have to decide which components or products to transition over to additive manufacturing, and in what order.
Additional questions will arise around facilities locations. How proximate should they be to which customers? How can highly customized orders be delivered as efficiently as they are produced? Should printing be centralized in plants or dispersed in a network of printers at distributors, at retailers, on trucks, or even in customers’ facilities Perhaps all of the above. The answers will change in real-time, adjusting to shifts in foreign exchange, labor costs, printer efficiency and capabilities, material costs, energy costs, and shipping costs.
Indeed, given all the potential efficiencies of highly integrated additive manufacturing, business process management may become the most important capability around. Some companies that excel in this area will build out proprietary coordination systems to secure a competitive advantage. Others will adopt and help to shape standard packages created by big software companies.
The Platform Opportunity From the Rise of 3D Printing In The Future
One position in the ecosystem will prove to be the most central and powerful—and this fact is not lost on the management teams of the biggest players already in the business of additive manufacturing, such as eBay, IBM, Autodesk, PTC, Materialise, Stratasys, and 3D Systems. Many are vying to develop the platforms on which other companies will build and connect. They know that the role of platform provider is the biggest strategic objective they could pursue and that it’s still very much up for grabs.
Platforms are a prominent feature in highly digitized 21st-century markets, and additive manufacturing will be no exception. Here platform owners will be powerful because production itself is likely to matter less over time. Already some companies are setting up contract “printer farms” that will effectively commoditize the making of products on demand. Even the valuable designs for printable products, being purely digital and easily shared, will be hard to hold tight. (For that matter, 3D scanning devices will make it possible to reverse-engineer products by capturing their geometric design information).
Everyone in the system will have a stake in sustaining the platforms on which production is dynamically orchestrated, blueprints are stored and continually enhanced, raw materials supplies are monitored and purchased, and customer orders are received. Those that control the digital ecosystem will sit in the middle of a tremendous volume of industrial transactions, collecting and selling valuable information. They will engage in arbitrage and divide the work up among trusted parties or assign it in-house when appropriate. They will trade printer capacity and designs all around the world, influencing prices by controlling or redirecting the “deal flow” for both. Like commodities arbitrageurs, they will finance trades or buy low and sell high with the asymmetric information they gain from overseeing millions of transactions.
Digital History Replicated
Thinking about the unfolding revolution in additive manufacturing, it’s hard not to reflect on that great transformative technology, the internet. In terms of the latter’s history, it might be fair to say that additive manufacturing is only in 1995. Hype levels were high that year, yet no one imagined how commerce and life would change in the coming decade, with the arrival of Wi-Fi, smartphones, and cloud computing. Few foresaw the day that internet-based artificial intelligence and software systems could run factories—and even city infrastructures—better
than people could.
The future of additive manufacturing will bring similar surprises that might look strictly logical in hindsight but are hard to picture today. Imagine how new, highly capable printers might replace highly skilled workers, shifting entire companies and even manufacturing-based countries into people-less production. In “machine organizations,” humans might work only to service the printers.
And that future will arrive quickly. Once companies put a toe in the water and experience the advantages of greater manufacturing flexibility, they tend to dive in deep. As materials science creates more printable substances, more manufacturers and products will follow. Local Motors recently demonstrated that it can print a good-looking roadster, including wheels, chassis, body, roof, interior seats, and dashboard but not yet drivetrain, from bottom to top in 48 hours. When it goes into production, the roadster, including the drivetrain, will be priced at approximately $20,000. As the cost of 3-D equipment and materials falls, traditional methods’ remaining advantages in
economies of scale are becoming a minor factor.
3D Printed Microfluidic Devices
Three-dimensional (3D) printing has revolutionized the microfabrication prototyping workflow over the past few years. With recent advances in 3D printing and 3D computer-aided design (CAD) technologies, highly complex microfluidic devices can be fabricated via single-step, rapid, and cost-effective protocols as a promising alternative to the time-consuming, costly, and sophisticated poly (dimethylsiloxane) (PDMS) molding and traditional clean room-based fabrication. Microfluidic devices have enabled a wide range of biochemical and clinical applications, such as cancer screening, micro-physiological system engineering, high-throughput drug testing, and point-of-care diagnostics. Using 3D printing fabrication techniques, the alteration of design features is significantly faster and easier than with traditional fabrication, enabling agile iterative and modular design, 3D printing services and marketplaces, and rapid prototyping. Biocompatible resins for 3D printing are now available that, contrary to PDMS, feature very low drug absorption and are thus very good material candidates for building complex 3D organ-on-a-chip systems in the future. These advances will make microfluidic technology more accessible to researchers in various fields and will accelerate innovation in the field of microfluidics.
Here’s what we can confidently expect: Within the next five years; we will have fully automated, high-speed, large-quantity additive manufacturing systems that are economical even for standardized parts. Owing to the flexibility of those systems, customization or fragmentation in many product categories will then take off, further reducing conventional mass production’s market share.
Smart business leaders aren’t waiting for all the details and eventualities to reveal themselves. They can see clearly enough that additive manufacturing developments will change the way products are designed, made, bought, and delivered. They are taking the first steps in the redesign of manufacturing systems. They are envisioning the claims they will stake in the emerging ecosystem. They are making the many layers of decisions that will add up to
the advantage in a new world of 3D printing.
