Cadillac Celestiq: The Future of Additive Manufacturing

Automotive additive manufacturing has been relatively slow to catch on since the technology emerged in the 1980s. It was readily adopted in the medical and aerospace industries much faster, but challenges regarding scalability and testing led to a slow start in the automotive industry. Regardless, this industry has gradually adopted additive manufacturing. Three-dimensional printing is accelerating changes in the industry and has the potential to generate as much as $9 billion in additional revenue by 2029.

Although you may not be able to drive an entirely 3D printed automobile yet, 3D printing has become an essential part of auto development. The technology adds tremendous value by speeding up the prototyping phase, smoothing supply chain challenges, and facilitating large-scale customization.

In 2024, the Cadillac Celestiq will make automotive history as the vehicle with the greatest number of 3D printed components. It also represents the automaker’s most technologically advanced vehicle, with 115 3D printed parts. The Cadillac Celestiq’s unveiling signals the potential for the future of 3D printing in the automotive industry.

ITS provides additive manufacturing testing solutions that help propel the technology forward and enable the expansion of ways to use additively manufactured parts. This gives us a unique window into this exciting new dimension in the automotive world.

Cadillac Celestiq Relies on 3D Printed Critical Parts

The Celestiq isn’t the first vehicle to use 3D printed components. However, with 115 3D printed components slated for its design, it will become the car with one of the highest numbers of 3D printed parts. Remarkably, many manufacturers use additively manufactured parts for non-critical components, such as trim, but Cadillac is using the technology for critical parts. Some of the outstanding features include:

General Motors’ First 3D Printed Safety-Related Part

GM intends to use 3D printed seat belt adjustable guide loops. These parts will be the manufacturer’s first safety-related parts created with additive manufacturing. The 114 other 3D parts will include grab handles, console décor, and window switches.

Celestiq Features GM’s Largest 3D Printed Part

This game-changing luxury automobile will use the largest sand 3D printer in the world to produce many of its components. The printer allows it to use an additively manufactured steering wheel center, which will be the company’s largest 3D printed metal part in production.

Celestiq Promises Personalized, Customized Luxury

Cadillac has a history of innovation, and the Celestiq promises to be the automaker’s latest example. In addition to being one of the first electric luxury vehicles that uses additive manufacturing, it will also be ultra-personalized and feature design touches and décor that traditional technology would never allow. In fact, the Celestiq’s embrace of additive manufacturing will allow it to deliver otherwise unprecedented personalization. No two vehicles will be alike because buyers will work with dealers and designers to create the vehicle of their dreams.

Additive Manufacturing Trends Drive the Auto Industry

Additive manufacturing and the auto industry have had a symbiotic relationship for decades. Ford bought the third 3D printer in existence, and many automakers and original equipment manufacturers (OEMs) have embraced the technology on a small scale.

In 2014, the industry began using additive manufacturing for large parts too. The now defunct Local Motors created the first 3D printed vehicle, the Strati. In the years since then, additive manufacturing has allowed for an acceleration of change. For example, additive manufacturing allows makers to deliver the following:

Actualization of Concept Cars

Not only does 3D printing bring experimental designs to life, but it also allows manufacturers like Lotus, Volvo, Nissan, and TATA to transform ideas into reality. Additive manufacturing reduces costs and increases the possibilities that are available in design.

Fast Prototyping

In addition to making designs more accessible, 3D printing speeds up the prototyping process. What could take weeks or months can be accomplished in a matter of hours with 3D printing. For example, Ford has a Germany-based Rapid Technology Center where the engineering team can produce same-day prototypes.

Lightweight Parts

One way to increase energy efficiency of a vehicle is through the use of lightweight materials. The Department of Energy estimates that for every 10% reduction in a vehicle’s weight, fuel efficiency increases by up to 8%. A Spanish automotive supplier uses 3D printing as part of its strategy to develop lightweight automotive products and rapid tooling using composite materials and plastics.

Cadillac Celestiq Is Just the Beginning

Automotive additive manufacturing allows Cadillac to provide unprecedented customization and handcraftsmanship in the Celestiq. At the same time, the question of whether the technology will reach mass production levels remains. The lack of reliable non-destructive testing methods has proven to be a stumbling block to the widespread adoption of 3D printing.

Innovation in testing is essential to ensuring 3D printed parts perform reliably. That’s where ITS shines, thanks to a full suite of testing solutions. We also customize testing to validate the use of 3D printed parts, which can help move the technology into the future.
