The Evolution of 3D Printing in Aerospace

Early Adoption and Development

The Aerospace and Defence (A&D) industry was among the earliest adopters of 3D printing technology. This early adoption has significantly contributed to the development and evolution of 3D printing. While some aerospace companies started experimenting with 3D printing in the 1980s, the technology has seen a significant increase in adoption over the following decades. Today, 3D printing is utilized in all phases of the design workflow in the aerospace industry.

Prototyping and Design Communication

One of the primary applications of 3D printing in aerospace is in prototyping. The ability to quickly produce prototypes at a lower cost is invaluable in an industry where innovation and precision are crucial. From full-size landing gear enclosures using low-cost FDM (Fused Deposition Modelling) to high-detail, full-color control board concept models, 3D printing caters to every prototyping need. Engineering materials used in 3D printing also allow for comprehensive testing and validation of prototype performance.

Manufacturing of Low-cost Rapid Tooling

3D printing has proven to be disruptive and valuable in producing low-cost rapid tooling for various manufacturing processes, including injection molding, thermoforming, and the creation of jigs and fixtures. In aerospace, this capability allows for the quick production of tooling at a lower cost, facilitating the manufacturing of low to medium runs of parts. This application is expected to drive the growth of the global aerospace 3D printing market.

Production Capabilities

While traditionally used for prototyping, advancements in 3D printing technology have made it a viable option for medium-sized production runs, especially for high-end interior build-outs. The technology is particularly impactful when the cost of producing intricate and unique components is justified by significant improvements in aircraft performance. Common 3D printing applications in aerospace include the creation of jigs and fixtures, surrogates, mounting brackets, and high-detail visual prototypes.

Enhancing Performance and Reducing Weight

Aerospace applications often require sophisticated engineering materials and complex geometries to reduce weight and enhance performance. 3D printing excels in producing intricate, lightweight, and highly stable structures, which is crucial for aerospace components. The technology allows for the creation of parts with internal channels, conformal cooling, thin walls, and complex curved surfaces, leading to topological optimization and the integration of functional features into a single element.

Surface Finish and Post-processing

Surface finish is vital in aerospace applications. 3D printed parts can be post-processed to achieve a very high degree of surface finish, meeting the stringent requirements of the aerospace industry. Processes such as SLS (Selective Laser Sintering), SLA (Stereolithography), DMLS/SLM (Direct Metal Laser Sintering/Selective Laser Melting), and Binder Jetting are commonly used in aerospace applications, utilizing materials like Glass-filled Nylon, Standard Resin, Nylon 12, Titanium, and Aluminium.

Adoption by Leading Aerospace Companies

Leading aerospace companies have recognized the benefits of 3D printing and have incorporated the technology into their production processes.

Airbus

Airbus has been a major proponent of additive manufacturing in the aerospace industry. The company installed the first titanium 3D-printed component for a serial production aircraft and has continued to integrate more 3D-printed parts into its aircraft. For example, the Airbus A350 XWB features over 1,000 3D printed parts. Airbus has also partnered with Swiss OEM Liebherr-Aerospace to source more serially produced 3D-printed components.

Boeing

Boeing has also been a significant adopter of 3D printing technology. In 2019, Boeing created the first 3D printed metal satellite antenna for Spacecom, an Israeli company. The antenna, used in the AMOS 17 satellite, replaced several parts in a large assembly with a single 3D printed part, reducing the weight and manufacturing time. Such advancements demonstrate the potential of 3D printing to revolutionize aerospace manufacturing.
