3D Printing Car Applications

3D printing is not just a prototyping tool; it’s a production powerhouse for car accessories and spare parts. The technology’s precision and versatility allow for the creation of a wide range of automotive components. Here are some examples of the car accessories and spare parts that can be 3D printed:

Custom Vents and Caps: Personalize your vehicle with custom-designed vents and caps that match your style.

Functional Pistons: Pistons are at the heart of your car’s engine, and 3D printing them can lead to improved performance and efficiency.

Dashboard Accessories: From smartphone holders to decorative elements, 3D printing allows you to customize your dashboard to your needs and tastes.

Replacement Knobs and Switches: Whether you’re restoring a classic car or updating your vehicle’s interior, 3D-printed knobs and switches are a perfect fit.

Door Handles and Hinges: These frequently used parts can wear out over time, but 3D printing offers a quick and precise replacement solution.

Custom Light Covers: Create unique light covers that enhance the aesthetic appeal of your car while ensuring safety on the road.

Prototypes for Testing: Before mass production, 3D printing allows for the creation of prototypes for aerodynamic testing and design verification.

3D Printing Car Advantages

Rapid Prototyping

3D printing accelerates the prototyping process, enabling manufacturers to move from concept to product quickly. This rapid prototyping capability significantly shortens the design and development lifecycle, allowing for faster innovation and speed-to-market.

Cost Reduction

Traditional prototyping methods like machining or injection molding can be costly and time-consuming. 3D printing reduces these costs by eliminating the need for expensive tooling and reducing material waste, making it a more economical option.

Design Freedom

Additive manufacturing allows for the creation of complex, organic shapes that are difficult or impossible to produce with conventional methods. This freedom in design enables engineers to explore more innovative and efficient car part solutions.


The ability to produce customized parts quickly and efficiently is a significant advantage of 3D printing. It opens up possibilities for personalized vehicle enhancements and made-to-order spare parts.

Sustainable Processes

With a focus on sustainability, 3D printing contributes to eco-friendly manufacturing practices by minimizing waste and enabling the use of recyclable materials.

On-Demand Production

The ability to print parts on demand aligns with lean manufacturing principles, reducing inventory costs and lead times and contributing to a more efficient supply chain.

3D Printed Car Parts Examples

1. Bugatti Bolide

The Bugatti Bolide is a remarkable example of how 3D printing technology is being utilized to push the boundaries of automotive design and performance.

4. BMW

The BMW Group is advancing the use of industrial-scale 3D printing within its production systems. The goal is to elevate additive manufacturing to industrial levels and integrate it systematically into vehicle development and production for economic benefits. This strategic move allows BMW to fully leverage the advantages of 3D printing, such as rapid component availability, flexible design, and the elimination of elaborate tooling for part manufacturing.

Since mid-2020, BMW has been using 3D printing to produce both metal and polymer parts for Rolls-Royce Motor Cars. These parts are used throughout the vehicle, including the body and passenger cell, and are known for their functionality and rigidity. The process was developed at BMW’s own Additive Manufacturing Campus, which also produces polymer parts through multi-jet fusion and selective laser sintering.

At BMW Group Plant Landshut, metal parts are created using laser beam melting, and these 3D-printed components are integrated into car bodies in an almost entirely automated process. The company also utilizes generative design in component development and employs artificial intelligence to screen components for additive manufacturability.
