3D printing has also made it possible to create parts that could not be made in any other way.

Bugatti's monobloc brake caliper is a prime example. For some components, Bugatti would have preferred titanium due to its high performance, but processing this metal with traditional methods is expensive and difficult. 3D printing has allowed Bugatti to produce a titanium alloy brake caliper. Due to the thin walls, the caliper turned out to be very light - almost two times lighter than forged aluminum. At the same time, the strength of the 3D-printed monoblock is superior to that of aluminum. The 3D printed titanium monoblock has a tensile strength of 1250 N/mm2. This means that a force of just over 125 kg will be applied per square millimeter of this titanium alloy without tearing the material. The new titanium caliper is 41 cm long, 21 cm wide and 13.6 cm high and weighs only 2.9kg compared to currently used aluminum, which weighs 4.9 kg.

3. Tool making

Various devices help to facilitate and speed up the production and assembly processes, improve the safety of workers. Automotive factories and component suppliers use a large number of non-standard tooling that is specifically designed and optimized for end use. As a result, a lot of non-standard equipment and tools are made, which increases production costs.

This 3D protective wheel disc was purchased for 800 euros but can now be printed for just 21 euros. Tool development time has been reduced from 56 to 10 days.

Delegating custom tooling and fixtures to service providers who machine parts from solid metal or plastic stock can delay production by weeks.

For example, the development and prototype of a commutator motor using traditional manufacturing methods can take up to four months and cost about half a million dollars. Thanks to 3D printing, Ford was able to develop several variants in just 4 days and 99.4% cheaper - only $3,000.

Additive technologies allow you to complete the task in a few hours and significantly reduce costs compared to ordering from a third-party enterprise. Since increasing the complexity of a 3D printed model does not incur additional costs, products can be better optimized for their application. New elastic materials for 3D printing in many cases allow you to print plastic parts instead of metal or create prototypes on a 3D printer to test the tool before using it in production

Gradually, the production of 3D printed accessories and tools is becoming one of the largest applications of additive technologies.

For example, Pankl Racing Systems uses a stack of multiple Formlabs SLA 3D printers to make critical manufacturing tools. The multi-stage production of parts for transmissions on automatic lathes requires a series of fixtures and tools designed for each specific part.

With the help of 3D printing, Pankl's engineers have reduced the production time for the aids by 90%, from 2-3 weeks to around 20 hours. Costs were also reduced by 80-90%, saving $150,000.

The transition to 3D printing has enabled Volkswagen Autoeuropa to cut tooling development costs by 91% and cut tooling times by 95%.

4. Troubleshooting spare parts

Spare parts have always been a problem for the automotive industry. The demand for them is either there or not, so the production of spare parts is not economically viable, and the storage of pre-fabricated replacement components is also costly. But if there are no repair parts available, difficulties arise and the main product becomes less valuable.

3D printing could solve the problem of parts in the automotive industry in many ways. The main factors are printed materials, which can match the characteristics of traditional materials used in parts and be cost-effective. There are prerequisites for this.

Using computer-aided design, drawings of all parts can be stored digitally, so there is no need to store the parts themselves. The parts needed by the client can be printed on a 3D printer right in the workshop.

Even obsolete parts whose drawings have not survived can in principle be recreated by making a 3D scan of existing parts of this type and applying reverse engineering (reverse engineering). You can read more about this on our blog. Old projects can take on new life. There are many lovers of vintage cars, with the help of 3D printing it would be possible to create parts for them.

5. Production of standard parts

As 3D printers and materials for 3D printing become more affordable, a gradual transition to the production of mass-produced automotive parts using additive technologies is possible.

3D printing makes it possible to combine components into a single whole. Let's say there is a mechanism assembled from six or seven car parts that can be combined into one printed part. It will save time and assembly costs. With 3D printing, it is also possible to reduce the weight of the combined assembly, as a result, the car will use fuel more efficiently.

3D Systems has developed an advanced exhaust pipe for a sport bike. In the image below, you will see 20 sheet metal and hydroformed parts needed to assemble the original exhaust pipe. On the right is a monolithic exhaust pipe that does not require assembly, made using metal 3D printing.

The 3D printed tube was produced using Grade23 titanium in just 23 hours, compared to three weeks for traditional production. Design development time reduced from 6 weeks to 6 days. Additive manufacturing also eliminates the need for tooling, fixtures, multiple welding and multiple inspections.

Geometry optimization has reduced the amount of material needed for maximum productivity. All elements of the original exhaust are included in the new design and, when printed at a typical wall thickness of 0.5mm, the 3D printed exhaust is about 25% lighter than the original.

A wide range of 3D printing materials is beginning to meet the requirements of various vehicle components. Since additive methods reduce costs compared to traditional methods (such as molding and injection molding), it makes a lot of sense from a production and financial point of view to further introduce 3D printing into the production of basic parts.

Volkswagen, one of the world's largest and most innovative car manufacturers, is using an HP Metal Jet 3D printer to produce high-performance functional parts with special design requirements, such as shift knobs and mirror mounts. Volkswagen's long-term plans to work with HP include accelerating the production of mass-customized parts such as key rings and exterior nameplates.

You can't buy a fully 3D printed car at a car dealership yet, but additive technologies have been used in car design for many years. Every year, especially in recent years, 3D printing is taking an increasingly important place at all stages of production. This is evidenced by the rapid growth of 3D printing market share in automotive manufacturing, which is projected to reach $2.5 billion by 2023.

For example, luxury car companies including Bentley, Porsche, BMW and Ferrari are using 3D printing to create custom car interior parts. GM, Volvo, Ford are using 3D printing to produce tooling to save money, improve designs and reduce delivery times.

3D printing is constantly emerging new opportunities, it is becoming more accessible. If the first 3D printers cost about $20,000, now you can find 3D equipment for $100. Now companies can, with the help of additive technologies, produce the necessary components directly at their own enterprises and not depend on suppliers.

With new materials, 3D printers can print high-precision, functional end parts. Additive technologies facilitate the production of custom products and increase productivity.

But this is only the beginning of the journey. Here are five key ways 3D printing is driving innovation in the automotive industry, from car design to manufacturing. Plus one bonus.

1. Changing the prototyping process

It was with the production of prototypes that the use of 3D printers in the automotive industry began. 3D printed prototypes took much less time than traditional methods required.

Using Raise3D 3D printers and ideaMaker software, Crazy Grandpa Garage was able to automate the process of creating custom car parts. Production costs have been reduced by 50%, design reliability has improved significantly, and lead time has been reduced by 83%. The parts now come out very well fitted to the car.

Using 3D printing, car designers can quickly prototype individual parts or assemblies, from interior detail to dashboard, or even full-size car models. Thanks to 3D prototyping, the initial idea quickly turns into a physical embodiment of the concept - a conceptual model. The concept can then be developed into full-featured, high-fidelity prototypes, and after several validation steps, mass production begins. For the automotive industry, getting through these steps quickly is vital, and the entire downtime of an automobile production line in just an hour is very costly for the company.

For example, the assembly plant of the US car manufacturer General Motors claims to have saved more than $300,000 by purchasing a 3D printer in 2016.

For example, General Motors has partnered with Autodesk to produce low cost, lightweight automotive parts using 3D printers. Tools, fixtures and fittings can now be produced at a fraction of the cost, according to Autodesk. For example, a 3D printed tool used to align engine and transmission ID numbers costs less than $3 at General Motors. A traditionally produced instrument will cost $3,000. In addition, downtime due to faulty tools can be significantly reduced as new tools are produced in-house.

2. Creating custom and complex parts

Daihatsu, the oldest car manufacturer in Japan, launched a project in 2016 to customize its Copen model.

In Europe, the BMW MINI brand also uses 3D printing to create personalized car parts. Since the beginning of 2018, MINI customers have been able to personalize various trim elements such as the dashboard, LED treadplates and illuminated bumpers, as well as choose from different colors and textures. These parts are then 3D printed using a range of technologies from DLS Carbon to SLS.

Large companies are merging 3D printing technologies with traditional manufacturing methods. Volkswagen has recreated its iconic 1962 Microbus by replacing the petrol engine with a 120-hp electric one. The Type 20 concept electric minivan has received many improvements using 3D printed parts. These improvements include cast aluminum wheels. Even the wheel hubcaps, while looking like stamped steel, are actually printed on a Formlabs SLA 3D printer, then electroplated and polished.

3. Tool and fixture making

A variety of fixtures help make manufacturing and assembly processes easier and faster, and improve worker safety. Automotive factories and component suppliers use a large number of non-standard tooling that is specifically designed and optimized for end use. As a result, a lot of non-standard equipment and tools are made, which increases production costs.
