Ford Motor Company is exploring how large one-piece auto parts, like car spoilers, could be printed for prototyping and future production vehicles, as the first automaker to pilot the Stratasys Infinite Build 3D printer.
Capable of printing car parts of practically any shape or length, the Stratasys Infinite Build system could be a breakthrough for vehicle manufacturing, providing a more efficient and affordable way to produce tooling, prototype parts, or components at low volumes, like Ford Performance vehicles, or for personalized car parts.
“With the Infinite Build technology, we are now able to print large tools, fixtures, and components, making us more nimble in design iterations,” said Ellen Lee, Ford technical leader for additive manufacturing research. “We’re excited to have early access to Stratasys’ new technology in order to help steer the development of large scale printing for automotive applications and requirements.”
The new 3D print system is located at Ford’s Research and Innovation Center in Dearborn.
An emerging technology for manufacturing
As 3D printing becomes increasingly efficient and affordable, companies are employing this emerging technology for manufacturing applications in everything from aerospace, to education, to medicine. Wider adoption in 3D printing has been driven by recent technology advances, new areas of application and government support, according to Global Industry Analysts Inc. By 2020, the global market for 3D printing is expected to reach $9.6 billion, the organization reported.
In the future, 3D printing could have immense benefits for automotive production, including the ability to produce lighter-weight parts, which may help improve fuel efficiency. A 3D-printed spoiler, for instance, may weigh less than half of its metal-cast equivalent.
Additionally, 3D printing is a more cost-efficient way to produce parts only needed at low volumes, like prototypes and specialized parts for racecars. Further, Ford also may use the technology to make larger printed tooling and fixtures as well as personalized components for customers.
How it works
Specifications for the part are transferred from the computer-aided design program to the printer’s computer, which analyzes the design. Then, the device goes to work, printing one layer of material at a time – in this case, plastic – and then gradually stacking the layers into a finished 3D object.
When the system detects that the raw material or supply material canister is empty, a robotic arm automatically replaces it with a full canister. This allows the printer to operate for hours or days while unattended.
Benefits of 3D printing
Though 3D printing isn’t yet fast enough for high-volume production manufacturing, it is a more cost-efficient way to produce parts only needed at low volumes, like prototypes and specialized parts for racecars. In addition, when not limited by the constraints of mass production processes, components can be designed to function more efficiently.
Using traditional methods, an engineer would create a computer model of the part and wait for months for prototype tooling to be produced. With 3D printing, Ford can print the same part in days at a significantly reduced cost. For example, a prototype for a new intake manifold could be produced over a couple of days as opposed to several months, at an order of magnitude lower cost.
Two-thirds of adults ready for cars that drive themselves
The latest Looking Further with Ford Trends Report reveals that behaviour is changing across key areas of our lives
Self-driving cars are a hot topic today, but if you had to choose, would you rather your children ride in an autonomous vehicle or drive with a stranger? You may be surprised to learn that 67 per cent of adults globally would opt for the self-driving car.
That insight is one of many revealed in the 2019 Looking Further with Ford Trend Report, released last week. The report takes a deep look into the drivers of behavioural change, specifically uncovering the dynamic relationships consumers have with the shifting landscape of technology.
Change is not always easy, particularly when it is driven by forces beyond our control. In a global survey of 14 countries, Ford’s research revealed that 87 per cent of adults believe technology is the biggest driver of change. And while 79 per cent of adults maintain that technology is a force for good, there are large segments of the population that have significant concerns. Some are afraid of artificial intelligence (AI). Others fear the impact of technology on our emotional wellbeing.
“Individually and collectively, these behavioural changes can take us from feeling helpless to feeling empowered, and unleash a world of wonder, hope and progress,” says Kuda Takura, smart mobility specialist at Ford Motor Company of Southern Africa. “At Ford we are deeply focused on human-centric design and are committed to finding mobility solutions that help improve the lives of consumers and their communities. In the context of change, we have to protect what we consider most valuable – having a trusted relationship with our customers. So, we are always deliberate and thoughtful about how we navigate change.”
Key insights from Ford’s 7th annual Trends Report:
Almost half of people around the world believe that fear drives change
Seven in 10 say that they are energised by change
87 per cent agree that technology is the biggest driver of today’s change
Eight in 10 citizens believe that technology is a force for good
45 per cent of adults globally report that they envy people who can disconnect from their devices
Seven out of 10 consumers agree that we should have a mandatory time-out from our devices

At last, cars talk to traffic lights to catch ‘green wave’
By ANDRE HAINZLMAIER, head of development of apps, connected services and smart city at Audi.
Stop-and-go traffic in cities is annoying. By contrast, we are pleased when we have a “green wave” – but we catch them far too seldom, unfortunately. With the Traffic Light Information function, drivers are more in control. They drive more efficiently and are more relaxed because they know 250 meters ahead of a traffic light whether they will catch it on green. In the future, anonymized data from our cars can help to switch traffic lights in cities to better phases and to optimise the traffic flow.
In the USA, Audi customers have been using the “Time-to-Green” function for two years: if the driver will reach the lights on red, a countdown in the Audi virtual cockpit or head-up display counts the seconds to the next green phase. This service is now available at more than 5,000 intersections in the USA, for example in cities like Denver, Houston, Las Vegas, Los Angeles, Portland and Washington D.C. In the US capital alone, about 1,000 intersections are linked to the Traffic Light Information function.
Since February, Audi has offered a further function in North America. The purpose of this is especially to enable driving on the “green wave”. “Green Light Optimized Speed Advisory” (GLOSA) shows to the driver in the ideal speed for reaching the next traffic light on green.
Both Time-to-Green and GLOSA will be activated for the start of operation in Ingolstadt in selected Audi models. These include all Audi e-tron models and the A4, A6, A7, A8, Q3, Q7 and Q8 to be produced from mid-July (“model year 2020”). The prerequisite is the “Audi connect Navigation & Infotainment” package and the optional “camera-based traffic sign recognition”.
Why is this function becoming available in Europe two years later than in the USA?
The challenges for the serial introduction of the service are much greater here than, for example, in the USA, where urban traffic light systems were planned over a large area and uniformly. In Europe, by contrast, the traffic infrastructure has developed more locally and decentrally – with a great variety of traffic technology. How quickly other cities are connected to this technology depends above all on whether data standards and interfaces get established and cities digitalise their traffic lights.
On this project, Audi is working with Traffic Technology Services (TTS). TTS prepares the raw data from city traffic management centres and transmits them to the Audi servers. From here, the information reaches the car via a fast Internet connection.
Audi is working to offer Traffic Light Information in further cities in Germany, Europe, Canada and the USA in the coming years. In the large east Chinese city of Wuxi, Audi and partners are testing networks between cars and traffic light systems in the context of a development project.
In future, Audi customers may be able to benefit from additional functions, for example when “green waves” are incorporated into the ideal route planning. It is also conceivable that Audi e-tron models, when cruising up to a red traffic light, will make increased used of braking energy in order to charge their batteries. Coupled with predictive adaptive cruise control (pACC), the cars could even brake automatically at red lights.
In the long term, urban traffic will benefit. When cars send anonymised data to the city, for example, traffic signals could operate more flexibly. Every driver knows the following situation: in the evening you wait at a red light – while no other car is to be seen far and wide. Networked traffic lights would then react according to demand. Drivers of other automotive brands will also profit from the development work that Audi is carrying out with Traffic Light Information – good news for cities, which are dependent on the anonymised data of large fleets to achieve the most efficient traffic management.
In future, V2I technologies like Traffic Light Information will facilitate automated driving.
A city is one of the most complex environments for an autonomous car. Nevertheless, the vehicle has to be able to handle the situation, even in rain and snow. Data exchange with the traffic infrastructure can be highly relevant here.
