CHAPTER 1: Aerospace & Defense
Pioneering the Adoption of 3D Printing
The aerospace and defense industry has been at the forefront of 3D printing adoption since its inception in the late 1980s. Major players in the industry, including GE, Airbus, Boeing, Safran, and GKN, have recognized the immense value that 3D printing brings to their operations. As a result, the aerospace and defense sector currently represents a significant share of the $10.4 billion additive manufacturing market.
Beyond Prototypes: Functional Parts Taking Flight
While 3D printing started as a tool for rapid prototyping, it has now advanced to the point where functional parts are being 3D printed and used in aircraft. The technology allows for the production of complex geometries without the need for expensive tooling equipment. Examples of 3D-printed aerospace components include air ducts (SLS), wall panels (FDM), and even structural metal components (DMLS, EBM, DED).
The Benefits of 3D Printing in Aerospace & Defense
The aerospace industry, with its requirement for highly complex parts produced in low volumes, greatly benefits from 3D printing. The technology enables cost-effective production of small batches of parts without the need for extensive tooling. Additionally, 3D printing allows for weight reduction, which is crucial for improving aircraft performance and reducing fuel consumption. The process also minimizes material waste, offers part consolidation opportunities, and facilitates maintenance and repair operations.
Real-World Applications
One remarkable example of 3D printing in the aerospace industry is the production of rocket components. Engineers are leveraging 3D printing, particularly with metals, to innovate the design and manufacture of rocket parts, significantly reducing production time. For instance, ArianeGroup, a joint venture of Airbus Group and Safran, developed a 3D-printed injector head for the Ariane 6 launcher, reducing 248 components down to a single 3D-printed part. This achievement resulted in a cost reduction of 50% and a production time decrease from three months to just 35 hours.
