Jonathan M. Gitlin shares an intriguing story about the advancements in additive manufacturing, also known as 3D printing, in the automotive industry. In his blog post, he focuses on Divergent 3D, a company that has been supplying 3D-printed parts for low-volume cars. Gitlin describes Divergent 3D’s partnership with car companies like Aston Martin and Mercedes-AMG and highlights its role in the production of subframes.

Gitlin then introduces another startup called Czinger, born out of Divergent’s printing technology. Czinger aims to build the world’s fastest production car and acts as a showcase for Divergent’s capabilities. The author shares his encounter with Kevin Czinger, the founder of Czinger, at the Goodwood Festival of Speed. He reveals that Divergent has expanded into the aviation industry, with General Atomics using their 3D-printed wings for drones.

The blog post continues with a review of the Czinger 21C, a tandem-seating hybrid supercar that has achieved remarkable track records. Gitlin emphasizes the weight-saving benefits of using 3D printing in the manufacturing process. He describes the organic and unique appearance of the car’s components, which result from parts consolidation and reduced mass using 3D printing techniques.

Gitlin incorporates quotes from Kevin Czinger, where he explains the importance of linking the creation of an actual product with the cost-productivity of the tools and material requirements. Czinger highlights the need for a printer designed specifically for the industrial-rate manufacturing they aim to achieve.

The author concludes by sharing Czinger’s plans to deliver the first 21Cs by the end of the year, meeting crash and emissions compliance standards. He also discusses Divergent’s entry into the aerospace industry, partnering with General Atomics to overcome production challenges in building smaller drones.

Revolutionizing Manufacture: How 3D Printing is Changing Aerospace Engineering

In a world where technology is rapidly evolving, the aerospace industry has always been at the forefront of innovation. From the creation of the first airplane to the development of cutting-edge spacecraft, engineers have consistently pushed the boundaries of what is possible. Now, a new technological marvel is revolutionizing the way aircraft are manufactured – 3D printing.

I recently had the privilege of speaking with John, a senior engineer at General Atomics, who shared with me the incredible advancements that 3D printing has brought to their aerospace manufacturing processes. “By integrating different things like fuel tanks into the skin and reducing the number of parts from over 180 to just 4, we have been able to achieve remarkable results,” he explained. “Even though we were using our aluminum alloy instead of carbon fiber, we managed to reduce the mass by over 5 percent.”

General Atomics, a leading aerospace and defense company, has taken full advantage of 3D printing technology. They have successfully implemented over 240 printed parts on their test aircraft, demonstrating the immense potential of this manufacturing technique. However, their ambitions don’t stop there. General Atomics aims to push the boundaries even further, targeting the 3D printing of 30–80 percent of the parts on a small drone in the near future.

One of the key advantages of 3D printing in aerospace engineering is the ability to consolidate multiple components into a single structure. By seamlessly integrating fuel tanks into the aircraft’s skin, General Atomics has reduced the overall number of parts required. This not only simplifies the manufacturing process but also enhances the structural integrity of the aircraft. It’s a win-win situation.

Furthermore, 3D printing allows for greater design freedom and flexibility. Engineers can now experiment with intricate and complex geometries that were once unimaginable. This has led to improved aerodynamics and enhanced performance, ultimately creating more efficient and capable aircraft. With 3D printing, the possibilities are endless.

The use of 3D printing has also significantly reduced manufacturing time and costs. Traditional methods often involve complex and time-consuming processes, such as molding and machining. By contrast, 3D printing enables rapid production of parts directly from digital designs, eliminating the need for expensive tooling and reducing lead times. This not only saves money but also enables engineers to iterate and refine designs more quickly, resulting in faster innovation.

While the aerospace industry has primarily relied on materials like carbon fiber for their lightweight properties, General Atomics has proven that even using aluminum alloy, 3D printing can still yield impressive weight reductions. This opens up new possibilities for manufacturers, enabling them to explore a wider range of materials and find the perfect balance between performance and cost-effectiveness.

As 3D printing technology continues to advance, it is clear that the aerospace industry is on the cusp of a manufacturing revolution. The integration of 3D printed parts into aircraft has demonstrated improved efficiency, reduced costs, and enhanced performance. It is only a matter of time before 3D printing becomes the norm in aerospace engineering, forever changing the way we design and manufacture aircraft.

General Atomics’ pioneering efforts in this field serve as an inspiration to engineers worldwide, reminding us that innovation knows no boundaries. With each passing day, 3D printing will continue to reshape the aerospace industry, propelling us towards a future where aircraft can be manufactured faster, lighter, and more efficiently than ever before.
