The Cadillac Celestiq Features GM’s Biggest 3D Printed Metal Part So Far

Advances in GM’s additive manufacturing – otherwise known as 3D printing – are showcased in the $340,000 EV halo sedan of its luxury brand, the 2025 Cadillac Celestiq, with the biggest single 3D-printed part yet to appear in a General Motors vehicle.

GM Authority has already covered how the Cadillac Celestiq features about 115 additively manufactured parts, which helps to make it more readily customized during its bespoke production process.

Now, GM has revealed that the Cadillac Celestiq steering wheel center is its biggest single 3D printed part across the whole range. The specific method used to create this component – which surrounds various buttons and other openings in the steering wheel in a single continuous piece – is metal laser powder bed fusion, which GM says makes “durable parts with geometries that are impossible to produce through traditional manufacturing processes.”

Designers considered several different ways of producing the steering wheel center. However, “additive won out because it can make a delicate, detailed, and compact part” according to Brennan White, a technical specialist. White said that 3D printing “allowed us to consolidate several parts into one continuous piece,” he remarked that “not only is it effortlessly beautiful, but the part is also incredibly strong.”

Some of the parts in the Cadillac Celestiq made using 3D metal printing include not only the steering wheel center, but also grab handles, structural components, and window switches among other components. The seat belt guide loop is a metal piece that is additively manufactured and GM’s “first 3D printed metal safety component.”

Both cost and function are considered when choosing whether or not to use 3D printing to produce a component for the Cadillac Celestiq. Additively manufactured parts are also appearing in the Cadillac V-Series Blackwing vehicles such as the Cadillac CT5-V Blackwing high-performance luxury sedan.

Brennan White also notes that “additive gave us something that we never could have achieved otherwise,” pointing out how 3D printing technology opens up new possibilities by creating continuous shapes that couldn’t be produced by even the most sophisticated older manufacturing techniques.

As a reminder, the 2025 Cadillac Celestiq is underpinned by the GM BEV3 platform, with power provided by the 111 kWh GM battery pack. The GM Global Technical Center in Warren, Michigan is the site of production for the highly customizable model.
