One of the most obvious signs of prosperity in the s was the growth of the automobile industry. Henry Ford dreamed of making an inexpensive car that almost anyone could afford to buy. Ford decided to apply to car manufacturing a method of mass production that was being used in some industries. Ford set up an assembly line that ran from one end of a building to another. At first, the line did not move. The workers walked along it, adding parts to the automobiles.

New developments in additive manufacturing processes will likely benefit production within the automotive industry as well as alter traditional manufacturing and supply chain pathways. Significant advances in additive manufacturing AM technologies, commonly known as 3D printing, over the past decade have transformed the potential ways in which products are designed, developed, manufactured, and distributed.
While automotive original equipment manufacturers OEMs and suppliers primarily use AM for rapid prototyping, the technical trajectory of AM makes a strong case for its use in product innovation and high-volume direct manufacturing in the future. New developments in AM processes, along with related innovations in fields such as advanced materials, will benefit production within the automotive industry as well as alter traditional manufacturing and supply chain pathways.
Visit the 3D Opportunity collection. Register for our upcoming course. In this report, we not only look at how AM can improve the competitive position of automakers but also explore the four paths OEMs and suppliers can take to more broadly apply AM.
We also explore the drivers supporting the use of AM and the potential challenges impeding its large-scale adoption in the automotive industry. For a detailed view on the different groups of technologies under the AM umbrella, refer to The 3D opportunity primer: The basics of additive manufacturing. Together, product innovation and supply chain transformation have the potential to alter the business models of automotive companies.
The extent to which the potential offered by AM is harnessed depends on the path chosen by individual companies. Four possible paths and their impact are described in the following framework figure 1.
The value from AM is in its ability to break two fundamental performance trade-offs: Capital versus scale and capital versus scope. On the other hand, AM facilitates an increase in flexibility and increases the scope, or variety of products that a given capital can produce. Achieving scale with less capital has the potential to impact how supply chains are configured, while achieving greater product scope with less capital has the potential to impact product designs. Our view of the strategic impact of AM relies on understanding the ways in which the technology breaks trade-offs between capital and economies of scale and scope.
Based on this understanding, we have developed an AM framework that identifies the tactical paths companies can follow as they seek business value using AM. This framework is summarized in figure 1. AM is an important technology innovation whose roots go back nearly three decades. Its importance is derived from its ability to break existing performance trade-offs in two fundamental ways. First, AM reduces the capital required to achieve economies of scale.
Second, it increases flexibility and reduces the capital required to achieve scope. Capital versus scale: Considerations of minimum efficient scale shape the supply chain.
AM has the potential to reduce the capital required to reach minimum efficient scale for production, thus lowering the barriers to entry to manufacturing for a given location. Capital versus scope: Economies of scope influence how and what products can be made.
Changing the capital versus scale relationship has the potential to impact how supply chains are configured, while changing the capital versus scope relationship has the potential to impact product designs.
These impacts present companies with choices on how to deploy AM across their businesses. The four tactical paths that companies can take are outlined in the framework below:. Path I: Companies do not seek radical alterations in either supply chains or products, but may explore AM technologies to improve value delivery for current products within existing supply chains.
Path II: Companies take advantage of scale economics offered by AM as a potential enabler of supply chain transformation for the products they offer. Path III : Companies take advantage of the scope economics offered by AM technologies to achieve new levels of performance or innovation in the products they offer.
Path IV: Companies alter both supply chains and products in the pursuit of new business models. Within the automotive industry, AM has largely been utilized to break the capital versus scope trade-off to enhance performance. High-volume automotive OEMs and suppliers have long applied AM to enhance overall manufacturing capabilities and reduce costs—which categorizes them as following path I of our framework.
AM has the ability to produce prototypes without creating tools, thus accelerating design cycles and lowering costs. Today both OEMs and suppliers use AM to enhance existing operations: to support decision-making at the product design stage, to establish quality at the preproduction stage, to develop custom tools, and to reduce the overall time to market.
Accelerating the product design phase of new product development: In the product design stage, companies go through several iterations before deciding on the final design.
Interestingly, the prototypes benefit the company by not only customizing options based on OEM needs but also enabling brand differentiation: The physical models give the company an advantage over competitors who may be limited to design specifications and plans alone when sharing new products with their OEM customers.
Enhancing quality via rapid prototyping : By using AM to create prototypes well before the final production, automakers are able to test for quality ahead of actual production schedules.
Given the design flexibility of AM, companies can build and test a large variety of prototypes. GM, for example, uses the AM technologies of selective laser sintering SLS and stereolithography SLA extensively in its preproduction and design processes across its functional areas—design, engineering, and manufacturing—with its rapid prototyping department producing test models of more than 20, components.
Another example is Dana, a supplier of driveline, sealing, and thermal management technologies for OEMs. It uses a combination of rapid prototyping and simulation to create prototypes that can be tested for form and fit. Customized fabrication of tooling: 10 For automakers, tooling plays a prominent role on the assembly line by producing consistent, high-quality products. AM allows for the fabrication of customized tools to enhance productivity on the shop floor.
BMW, for example, has used AM in direct manufacturing to make the hand tools used in testing and assembly. Reducing tooling costs in product design: For some automotive components, tooling and investment castings are prepared for specific designs prior to production runs. This means that with every design change, tooling has to be appropriately adjusted or remade—a time-consuming and expensive process.
OEMs have reduced their dependence on tooling and casting in the design phase by using AM. By additively manufacturing prototypes of components such as cylinder heads, intake manifolds, and air vents, the company also cut down drastically on the time that would usually be required to create investment castings.
Most automakers today operate on path I—which offers them ample scope to improve their AM strategies. However, this route also includes product innovation typically associated with path III. The automotive business model of the future will likely be characterized by OEMs working closely with a smaller, more tightly knit supplier base and supporting faster refresh rates for automobiles with innovative characteristics.
With AM, automakers can significantly shorten the development phase of the product life cycle and expand the growth and maturity phases. AM capabilities along this path break the traditional capital versus scope trade-off, driving down the capital intensity required for innovation.
A critical advantage in the near term of using AM is the potential production of components with lower weight, leading to vehicles with improved fuel efficiency. Over the longer term, AM-enabled part simplification and associated reductions in the complexity of assembly could fundamentally change design-development-assembly processes.
More complex designs that drive weight reduction : Automakers are constantly seeking ways to improve the fuel efficiency of vehicles—not only because of increasing demand for compliance with fuel standards such as Corporate Average Fuel Economy but also as a way to grow revenue by delivering greater value to consumers. One of the routes that automakers are taking to improve mileage is through weight reduction in automobiles. Over the years, OEMs have sought to incorporate lighter materials such as carbon fiber and aluminum into the vehicle body.
The Ford F is a good example. The ability of AM to create complicated configurations plays an important role in reducing the weight of parts using lattice structures without compromising structural strength. Reducing assembly and production cost through part simplification : Conventional manufacturing techniques impose design limitations that can proliferate the number of parts required to produce a component.
As the number of parts increases, the length and complexity of the assembly process also increase. Fewer parts translate into a shorter assembly process, and consequently there is less chance that a quality problem will arise. Some auto companies are already making use of these attributes of AM, albeit in a limited fashion. Delphi, a tier 1 automotive supplier, currently uses selective laser melting SLM instead of traditional machining of aluminum die castings to make aluminum diesel pumps.
Producing pumps as a single piece also helped Delphi avoid several postprocessing steps, resulting in a final product that is less prone to leakage. Greater application of AM freeform capability in the future can simultaneously reduce assembly time and cut down on assembly costs, with the integration of individual parts such as flow control valves, mounts, and pumps into a single-part design.
This way, even complicated systems such as complete engine blocks can be built as a single part, with integrated electrical and cooling channels. The optimized engine design can improve fuel efficiency and lower weight. The eventual path for automotive OEMs is business model evolution through a combination of product innovation, rapid turnaround, and market responsiveness, leading to AM-supported supply chain disintermediation.
Business model innovation will incorporate the current-use path I advantages of AM—improved design and reduced time to market—along with the intermediate product innovation path III advantages—part simplification, reduced need for assembly, and weight reduction of components—that we have previously discussed; it can then combine these with a more geographically distributed supply chain to alter business models in important ways related to market responsiveness and supply chain disintermediation.
Customization and improved market responsiveness : Advances in AM technology and adoption are leading to product innovations that will transition AM from a product-design support tool to a conduit for the direct production of high-performance parts with fast turnaround.
While automotive companies have conventionally used modularity and postponement to support customization, AM provides greater flexibility. An interesting segment of the auto industry that has already adopted AM is the ultraluxury segment. In this segment, where production runs are small, AM is being used to customize and manufacture parts for use in final assembly. Some ultraluxury car makers already use AM to deliver designs specialized to customer requirements.
Bentley, for example, used its in-house AM capabilities to customize the dashboard in a case where manual modification would have been time consuming. Using AM for the rapid turnaround of application-specific parts is presently prominent in the proving ground of new auto technologies—motor sports.
With lead time becoming a precious commodity, lessons learned in motor sports can be applied to mass production to reduce turnaround times—a competitive capability that will likely become increasingly critical for all automakers. One of the best motor sports examples comes from Joe Gibbs Racing, which used AM to produce a duct outlet and reduced the design and machining time from 33 to just 3 days.
The question is how to transfer the advantages of AM from the small scale of motor sports and ultraluxury segments to mass-market vehicles. In this regard, the experience of the medical technology medtech industry offers important lessons.
Yet they can be produced on a large scale using AM. An important effect of AM may be shortening and simplifying the enormous automotive supply chains that currently operate. OEMs work with thousands of suppliers to source the different components in cars. Owing to the fact that supply chain management is a massive planning and logistics exercise, consuming time, effort, and cost, OEMs are constantly seeking ways to trim their supply chains.
Ford, for example, was working with over 1, suppliers in In October it announced intentions to cut this number by as much as 40 percent. Conventionally, OEMs outsource the manufacturing for most components.
OEMs accounted for about 35 percent of total value created, while suppliers accounted for the rest in A greater role for OEMs could represent a major shift in the industry, causing a ripple effect on lower-tier suppliers, who might see a smaller role and greater consolidation in the future. An important but highly fragmented part of the automotive supply chain is the aftermarket parts and accessories industry, which is likely to follow a different path from the OEMs see sidebar.
Using AM, automotive suppliers can produce components on demand and at locations closer to the point of use. This affords them the added benefit of balancing demand and supply and drastically lowers the cost of inventory.
In addition, maintenance and repairs of automobile parts can be done in entirely new ways using newer AM technologies, which can potentially reduce long lead times to get cars back on the road. Reducing service, spare, and aftermarket part inventory: Delivery time and parts availability is an important basis of competition in the aftermarket segment of the automotive industry.
Owing to high costs of carrying inventory, most automotive part distributors and retailers hold only commonly sold parts, maintaining stockpiles of low-demand or expensive components only at more remote, consolidated locations.
Yes, it halted completely. No cars, commercial trucks, or auto parts were made from February to October As a temporary measure, local rationing boards could issue permits allowing persons who had contracted for cars before January 1st to secure delivery. It superseded the Office of Production Management.

Studies have shown that in the US , Europe , and in China , producing an electric vehicle creates more greenhouse-gas emissions than producing an equivalent gas-powered vehicle. The biggest reason for that disparity is an electric vehicle's battery, which can account for about a quarter of its weight, Colby Self, the managing director at the Automotive Science group, told Business Insider. Electric-vehicle batteries are bigger than those used in gas-powered cars and feature a different kind of chemistry.
