General Motors (GM) has been leveraging additive manufacturing for many years to expedite vehicle development by producing functional prototypes. Recently, the company has advanced its approach by integrating 3D printing into automobile production, specifically for low-volume models such as the Cadillac CELESTIQ. GM made a significant investment of $81 million in additive manufacturing dedicated to the CELESTIQ a few years ago, and the vehicle has now been launched featuring several 3D printed components.<\/p>\n
The CELESTIQ is a luxury electric sedan designed to elevate the Cadillac brand’s prestige. It distinguishes itself as one of GM’s most customizable models, incorporating over 130 3D printed components. This technology’s precision and adaptability make it an excellent fit for crafting unique, high-quality parts.<\/p>\n
A standout feature of the CELESTIQ is its flywheel hub, produced using laser powder bed fusion (L-PBF). This innovative technique enables the creation of complex and durable metal parts that would be beyond the capabilities of traditional manufacturing. The steering wheel component is not only elegant but also integrates LED backlighting visible through the material, enhancing the vehicle\u2019s sophisticated feel. To date, this component represents the largest metal part mass-produced by GM employing 3D printing.<\/p>\n
Another notable 3D printed element is the adjustable seat belt guide ring, marking GM’s inaugural use of a 3D printed metal safety component. These parts are primarily manufactured at GM’s Additive Industrialization Center (AIC) in Warren, Michigan, a facility opened in December 2020 with over 20 machines capable of printing in both polymeric and metallic materials across 1,400 square meters.<\/p>\n
Brennon White, a technical specialist at GM, remarked, \u201cWhen considering additive manufacturing, we assess if it meets functional requirements and is economically feasible. If both criteria are met, we target additive manufacturing. That\u2019s what we did with CELESTIQ, as additive provided us capabilities we never could have achieved otherwise.\u201d Other components, including window switches, handles, decorative console elements, and internal structures, were initially developed at AIC and later produced by specialized suppliers. This model has the highest concentration of 3D printed components in GM’s lineup, reflecting the company’s commitment to innovation.<\/p>\n
