How 3D Printing is changing the Car Industry

Mar 23, 2023 | Automotive, Design, Development, Manufacturing, News, Performance

Although 3D printing has been a vital part of the automobile development process for cars for years, it has recently gained a foothold throughout manufacturing.

Also known as additive manufacturing, 3D printing has added enormous value to the industry whether it be manufacturing parts or reducing time spent.

As 3D printing technology continues to advance, it is expected to play an increasingly important role in the car industry, revolutionising the way cars are designed, manufactured, and customised.

Here are the ways 3D printing is changing the car industry.


Same-Day Prototypes

Many 3D printing technologies are used to create prototypes with short turnaround times. This is the case at Ford’s Rapid Technology Centre in Merkenich, Germany.

Instead of sending out a job to a shop with a several-week lead time, engineers and designers are able to get their designs in a matter of hours. At the Rapid Technology Centre, designers are able to produce same-day prototypes.

According to Bruno Alves, additive manufacturing expert at Ford, physical prototypes can offer advantages over digital models. For example, Formlabs 3D printers were used to prototype the lettering on the back of the Ford Puma. This allowed designers to see how the lines and shadows would appear in various lighting conditions.

Alves says: “The printer is so fast, and so effective for this kind of lettering, that we could supply the designers the option to iterate. It’s a thing that you can see it in CATIA or other software, you can simulate lighting, but it’s different to feel, to touch, and to see all the reflections when you put the lettering on the car.”


Turning Concept Cars into Reality

When it comes to 3D printing in the motoring industry, more concept cars are turning into reality. One company doing such things is the UK-based Vital Auto.

When the original equipment manufacturers (OEMs) do not have time for experimentation themselves, they come to Vital to turn ideas, initial sketches, drawings, or technical specifications into a fully realised physical form.

Anthony Barnicott, Design Engineer in charge of additive manufacturing, says: “We’ve used 3D printing from day one. We wanted to introduce it to our manufacturing processes, not only to reduce costs but to give the customer more diversity with their designs and their ideas.”

“We use these printers for all areas of our concepts and designs. Typically, we use the Fuse 1s for our production-based parts and we use our Form 3Ls for our concept-based parts. Not only does 3D printing help create better products faster but it also attracts new business.

Barnicott added: “The progression in technology and 3D printing over the last 10 years is phenomenal. When I first started, producing low-volume, niche vehicles, some of the products that we produce today would simply have been inaccessible.

“And not only am I able to produce these parts today, but I’m also able to produce them very cost-effectively, very quickly.”


Lightweight Car Parts

IGESTEK is an automotive supplier in Spain that develops lightweight solutions using plastics and composite materials. The company uses 3D printing throughout the product development process.

They also use 3D printing to manufacture rapid tooling, such as inserts for plastic injection moulds or thermoforming tools for composites.

For one suspension mount, the team developed a multi-material architecture that combines metal 3D printing based on generative geometries and lighter composite materials to offer the best performance, in a 40% lighter package than current solutions on the market.


Improved Engine Performance

Following the release of the Toyota Yaris GR, the engineers at Forge Motorsport noticed a few ways to improve the inlet duct design. They reverse-engineered the OEM part using 3D scanning. Using SOLIDWORKS, they were able to simulate airflow.

Once they had a workable 3D model, they prototyped it in fast-printing Draft Resin, which they used to confirm that the new location for the airbox opening would work as intended and that the overall increased size of the part wouldn’t interfere with other components or cables.

With basic fit confirmed, they reprinted the part in Tough 1500 Resin, a strong and impact-resistant material, painted it black to resemble the final part, and gave it to a customer to test.

Over a five-month period, the 3D-printed part produced a lower intake air temperature and there were reduced fluctuations. The company moved forward by using carbon fibre to manufacture the final production part.


3D printing is revolutionising the car industry by offering a range of benefits that were previously impossible. This technology is enabling faster and more cost-effective product development through rapid prototyping, allowing manufacturers to test and refine designs more efficiently.

By facilitating the creation of customised parts and accessories, 3D printing is also enabling car manufacturers to offer a higher level of personalisation to their customers.

As 3D printing technology continues to evolve, its impact on the car industry is likely to become even more significant, transforming the way cars are designed, manufactured, and customised in the future.
