It might actually be the most beautiful thing I have ever seen.” This sentiment perfectly articulates the profound impact of the E-Type and the exceptional quality of Eagle’s restorations.

Modern Methods for Timeless Machines: Eagle Embraces 3D Printing

While the cars Eagle restores are quintessential classics, the manufacturing methodologies employed by the company are anything but traditional. Recognizing the inherent challenges and limitations of conventional production techniques for bespoke vintage car parts, Eagle embarked on a journey into the world of 3D printing technologies four years ago. This strategic shift has allowed them to overcome obstacles such as the prohibitive costs and lengthy lead times associated with creating molds for low-volume, specialized components. For much of this period, Eagle has maintained a productive collaboration with Graphite Additive Manufacturing Ltd., a respected 3D printing service provider based in the UK, leveraging their expertise to bring complex designs to life. However, a significant evolution in their additive manufacturing strategy occurred recently with their decision to integrate HP’s cutting-edge technology, specifically the HP Jet Fusion 4200 system, into their workflow.

The Power of HP Jet Fusion: Tailored Solutions for Bespoke Parts

Graphite Additive Manufacturing, in partnership with Eagle, harnesses the advanced capabilities of HP’s Multi Jet Fusion (MJF) 3D printing technology to produce custom, one-off, or small batch parts essential for the intricate restoration of the vintage Jaguar E-Types. Components such as air conditioning and heating air ducts, which are often complex in geometry and critical for both function and aesthetics, are ideal candidates for this manufacturing approach. Given that Eagle typically re-manufactures only between four to five of these exquisite cars annually, the demand for bespoke parts is inherently low volume. In such scenarios, traditional manufacturing methods, which often necessitate the creation of expensive and time-consuming designated molds, would represent an enormous waste of resources – both financial and temporal. Additive manufacturing, in contrast, perfectly aligns with these low production requirements, offering a highly agile and cost-effective solution.
