Over the years, the possibilities offered by additive manufacturing technologies have had a significant influence on the automotive industry. For both global car manufacturers and small service workshops, the implementation of 3D printers has made it possible to cut costs, shorten lead times, or fabricate unavailable automobile parts. On top of that, 3D printing in the automotive has largely improved the workflow in such areas as custom designing, prototyping or producing tools required for the assembly lines. Here’s an overview of seven 3D printing applications in automotive which illustrate the impact of AM technologies on this sector.

3D Printed Custom Tooling in Toyota Factories

One of the largest automotive factories in Europe, which deals with assembling Toyota cars engines, has been using 3D printed custom tooling on its production lines for many years now. Multiple 3D printed jigs and fixtures help to optimize the workflow in huge processes that have significant production output. Because the engines are assembled from the parts delivered from other Toyota plants, the supervising engineers design and 3D print jigs, tools, and covers that make the whole work faster, and bring repeatable results. Some items 3D printed for the automotive factory are positioning jigs, which are used to confirm that individual components of an assembled part are in the correct position towards one another. There are also 3D printed seals which are used to protect the engine parts when they are moved between the workstations in the factory.



As Łukasz Kondek, a 3D printing engineer at the Toyota factory, says: “Jigs that are 3D printed in the automotive industry today used to be made by a separate tooling division equipped with CNC machines. Currently, over 95% of jigs are manufactured using the LPD technology on a Zortrax M300 Plus 3D printer.” The tooling and other spare parts can be 3D printed on demand, with designs that can be optimized for a given task. 3D printers in automotive can fabricate almost all possible geometries.

Industrial 3D Printing at an Automotive Manufacturing Plant - RM Motors 

Another example which shows how 3D printing can be employed at an automotive plant comes from RM Motors, a Polish manufacturer of cars' exhaust systems. By implementing an industrial 3D printer in their production hall, the company was able to customize other specialized machines with 3D printed models. The roll press, which is used for stamping thermal insulation on a daily basis by RM Motors engineers, has to be adjusted to produce specific shapes of the insulation with a die and a stamp. That's why, instead of having those components CNC-milled, which is expensive and time-consuming, the engineers simply modeled and 3D printed them. Having two Zortrax Endureal industrial 3D printers in their workshop allows the team to obtain any shape that is required to fabricate their products. In this case, 3D printing in automotive translates into utility projects which can significantly facilitate the workflow of the whole production. 3D printers can effectively replace CNC machines in areas where geometries necessary for production must be delivered quickly and flexibly.



Designing a Performance Motorbike by Vins Motors 

At an earlier stage of vehicle production, that is designing, 3D printing is equally useful. Vins Motors, an Italian company founded by former Ferrari engineers, has designed a performance motorbike, called Dueacinquanta, with a revolutionary 2-stroke engine and innovative approach to aerodynamics of the vehicle. With such a clear vision to produce an ultra-light motorbike with a carbon fiber chassis, in which each part had to perform at least two functions, the prototyping stage required a meticulous approach. All parts of both the chassis and the engine were designed in CAD software and 3D printed on Zortrax M300 out of filaments like ABS and HIPS. Vincenzo Mattia, the person who stands behind the idea for the motorbike, admits that “a 3D printer in automotive offers a completely automated process which became a natural way of communicating design ideas.” Mattia’s company 3D printed enough parts to build an entire full-scale model of the motorbike, which they used as a pre-production display prototype at motorcycles’ fair.   



3D Printing in a Project of an Electric Motorbike by Falectra

Another example of how additive manufacturing technologies have enabled the production of a two-wheeled vehicle comes from Poland. Falectra is the first Polish electric motorbike brand founded by Piotr Krzyczkowski who decided to enter the e-mobility sector with his idea for a green and economical urban transportation solution. However, for his start-up company to gain funds from investors, he needed something more than a virtual project. To fit the tight budget, he decided to employ 3D printing as one of the manufacturing methods for the prototype. Around 10 parts of the vehicle were made with the use of Zortrax M200 Plus and M300 Plus — the front gate, rear fender, side covers, air inlet for charging the battery and a mounting part of the front lamp. In half a year, Krzyczkowski created a fully functional prototype, consisting of mostly 3D printed parts, and evaluated the bike’s potential for mass production, which is the key factor when developing a product: “The whole process cost almost seven times less and we were able to show the world a functioning motorcycle,” says Krzyczkowski. 



3D Printing Spare Parts for Classic Cars: ABcars and Alfa Project

Yet another business model in the automotive sector where 3D printers are an indispensable tool is car restoration. Fabricating the parts that are damaged or missing in a vintage car usually involves working with old design documents, photographs, or any component that is left in a particular vehicle. In most cases, the additive manufacturing technologies make it possible to obtain elements which have been out of production for decades. One of the companies working in that field is ABcar Oldtimers from Poland. They used Zortrax Inkspire 3D printer to fabricate items of the steering wheel in a Ferrari 599 or elements of the dashboard in a vintage Mercedes Benz. Also, the M300 Plus and M200 3D printers helped the team restore a classic Porsche 911. “3D printing in automotive is incredibly helpful. It speeds up work and limits costs linked to prototyping individual parts. Additionally, elements 3D printed for cars work just fine and do not change their properties over time,” points out Bartłomiej Błaszczak, Design & Engineering Director at ABcar Oldtimers. 



Alfa Project is another company which has taken a similar approach with 3D printing in automotive. Through reverse engineering, they reproduce damaged and unavailable parts in classic Alfa Romeo cars. They 3D model and reproduce spoilers, bumpers, gear knobs, gearbox mechanism covers, mirror holders, and multiple elements of the dashboard, such as clock frames, air vents, AC control panels, or blanking plates. Since these plastic elements have been susceptible to damage through regular use, the team enhances each part’s design in CAD software. With features, such as strengthening ribs, Alfa Project continues the work on their Zortrax M300 Plus to 3D print high-quality ABS elements. “In printed plastic elements, ABS gives a satisfactory temperature resistance, and is adequately resistant to bending at the same time. It can be used in 3D models with fasteners or anchoring elements,” claims Mateusz Dziwisz from the team.

Customizing Cars with Durable 3D Printed Components - Indrė Zabielaitė

On the other end of the spectrum, there are hobbyists and true car enthusiasts who want to customize and upgrade their vehicles in a cost-efficient way. 3D printing is one the technologies that perfectly fits car-tuning projects. Indrė Zabielaitė from the 3D Creative team upgraded her MINI Cooper with a used bumper coming from the MINI’s newer edition. However, the air intakes in the bumper that she ordered were damaged and unfit for being installed in her car. Therefore, with the access to a 3D scanner and a Zortrax M300 Plus 3D printer, Indrė produced new intakes, which after some post-processing, were fully functional and nicely fitted the entire bumper. The elements she 3D printed for a car are durable enough to be used in changing conditions: “I drive this car daily, even in winter and the 3D prints still look amazing. I’m truly satisfied with the quality,” Indrė sums up. 3D printing allowed Indrė to realize her vision for a car upgrade while maintaining low costs of the job.
