How Automakers Are Using 3D Printers to Make Car Parts

Automakers are increasingly turning to 3D printing to develop vehicle components, improve manufacturing efficiency and reduce production costs. The technology, known as additive manufacturing, is changing how companies design, test and produce everything from small interior components to specialized metal parts and factory assembly tools.

Major automotive manufacturers, including General Motors, Ford and BMW, are investing in the technology as they look for faster, more flexible ways to build vehicles and improve production processes.

What Is 3D Printing in Automotive Manufacturing?

3D printing, also called additive manufacturing, is a process that creates physical objects from digital designs by building them layer by layer. Unlike traditional manufacturing methods that often involve cutting, drilling or removing material from larger pieces, additive manufacturing builds components by adding material only where it is needed.

Depending on the printer and application, manufacturers can use plastics, resins, metal powders and composite materials to create different components. The technology allows engineers to develop complicated shapes and customized designs that can be difficult or expensive to manufacture using traditional production methods. Automakers use 3D printing for everything from early vehicle prototypes and specialized manufacturing equipment to functional components installed in production vehicles.

General Motors Uses 3D Printing in Production Vehicles

General Motors has been using additive manufacturing for more than 30 years, initially focusing on prototypes and engineering development. The company has increasingly expanded its use of the technology into manufacturing facilities and production vehicles.

In January 2025, GM reported completing more than 5,400 new additive manufacturing projects during 2024. Its applications included early component prototypes, manufacturing tools, production fixtures and equipment designed to make assembly-line work easier.

One example involved GM’s Lansing Delta Township Assembly plant in Michigan. Workers previously used metal fixtures weighing approximately 14 pounds to hold vehicle hoods in position during assembly. GM developed a lighter 3D-printed replacement to make the process easier and address workplace ergonomic concerns.

The company has also incorporated 3D-printed components into the Cadillac CELESTIQ, its hand-built luxury electric sedan. According to GM, the vehicle features more than 130 components produced through additive manufacturing.

These include a metal steering wheel center and a specially designed seat belt adjustable guide loop. The steering wheel component uses metal laser powder bed fusion, a process that builds parts by fusing successive layers of metal powder with a laser.

BMW Expands 3D Printing Across Its Manufacturing Operations

BMW has also made additive manufacturing an important part of its production strategy. The automaker has used 3D printing since 1991 to develop prototypes, specialized vehicle components and manufacturing equipment.

In October 2024, BMW reported producing more than 400,000 3D-printed parts annually across its global operations. The company also highlighted how the technology is being used to manufacture specialized robot grippers and other equipment used on production lines.

Some of these components are designed to be significantly lighter than traditionally manufactured alternatives. This can help robots operate more efficiently, reduce energy consumption and improve manufacturing speeds.

In July 2026, BMW announced additional plans to expand additive manufacturing through increased automation and new production systems. The company said it expects to begin series production using Wire Arc Additive Manufacturing technology in 2027. This metal-printing process uses an electric arc to melt wire and build components layer by layer. BMW’s investment reflects a broader effort to move 3D printing beyond prototypes and into larger-scale industrial manufacturing.

Ford Uses 3D Printing for Racing and Vehicle Components

Ford is exploring additive manufacturing for both motorsports and conventional vehicle production. In February 2025, the automaker revealed that its manufacturing team had already produced approximately 1,000 3D-printed components for its partnership with Red Bull Powertrains ahead of the 2026 Formula One season.

The components include specialized metal and polymer parts designed for demanding racing conditions. Engineers subject the parts to extensive testing, including mechanical strength evaluations, X-ray inspections and CT scans. The technology allows engineers to produce complicated components that would be difficult to create using conventional manufacturing techniques.

Ford has also explored ways to make 3D printing more sustainable. In a 2021 collaboration with HP, the company developed a process to recycle used 3D-printing materials into injection-molded fuel-line clips for Ford Super Duty F-250 trucks. According to Ford, the recycled-material components were 7% lighter and cost 10% less than conventional versions.

How 3D Printing Could Change the Automotive Industry

One of the biggest advantages of additive manufacturing is the ability to produce specialized components without relying on expensive traditional tooling for every design. Engineers can make adjustments to digital designs and produce updated parts relatively quickly. This can shorten development timelines, support customized vehicle designs and help manufacturers test new ideas before committing to larger production runs.

The technology can also reduce material waste in certain applications because components are built using the material required for their designs rather than cutting away excess material.

However, 3D printing is not expected to replace traditional automotive manufacturing entirely. Cost, production speed, material performance and safety requirements still determine whether a component is suitable for additive manufacturing.

For high-volume vehicle components, conventional manufacturing methods can remain more economical. Every production part must also meet the automaker’s engineering, durability and safety requirements.

The Future of 3D-Printed Car Parts

As printing technology advances, automakers are finding more ways to incorporate additive manufacturing into vehicle development and factory operations. From specialized steering wheel components and lightweight robot grippers to motorsports equipment and assembly-line tools, 3D printing is already playing a role in modern automotive production.

With companies such as GM, Ford and BMW continuing to invest in the technology, additive manufacturing could become an increasingly important part of how future vehicles are designed, tested and built.

The biggest change is that 3D printing is no longer limited to creating experimental prototypes. Automakers are increasingly finding practical ways to use it in real manufacturing operations.
