Aerospace and Defense

Aerospace and defense companies use best-in-class software like CATIA, SOLIDWORKS and many other adjacent technologies. Popular organizations like NASA, SpaceX and Lockheed Martin use CATIA and SOLIDWORKS.

In addition to CAD software, these companies also use data management solutions, simulation and analysis tools and MES (Manufacturing Execution Software.)

Data management solutions are ideal for any company. For the aerospace industry, these solutions provide one common documentation system, allowing teams to easily trace every approval and person who operated on the aircraft — down to a single bolt.

Having a well-documented system also helps product development teams meet strict regulatory requirements set by top aviation authorities like the Federal Aviation Administration (FAA) or the European Union Aviation Safety Agency (EASA).

Aerospace engineers can benefit from various simulation software because they have numerous study types that help ensure designs and parts meet safety and performance requirements.

One of the most challenging aspects of aerospace engineering is designing for extreme conditions, such as high altitudes, low temperatures, high speeds and harsh environments. These conditions affect the performance, durability and safety of aerospace systems and components, and require careful consideration of factors, such as aerodynamics, thermodynamics, materials and structures.

For example, aerospace engineers need to design aircraft and spacecraft that can withstand high dynamic pressures, thermal stresses, vibration, shock and fatigue, while also minimizing drag, weight and noise. To achieve this, aerospace engineers use advanced computational tools, simulation models and experimental methods to analyze and optimize their designs, and test them in various facilities, such as wind tunnels, vacuum chambers and flight simulators.

Additive manufacturing for aerospace and defense organizations helps organizations create complex geometries, reduce weight, and improve functionality. In this sector, additive manufacturing is transforming the way components and parts are designed and manufactured for space flight, satellites, propulsion systems, heat exchangers and electric engines.

Aerospace and defense companies who are early adopters of additive manufacturing range from smaller organizations who use it to lightweight drone parts to large, global companies that use it across their manufacturing lines.

Here are some examples:

• Boeing uses SLS printing to make 150 different parts for the F/A-18E Super Hornet aircraft which is used by air forces around the globe.
• Cabin Management Solutions and the U.S. Department of Defense both leverage 3D printing to replace low-volume, high-value parts for aircraft at lower costs and accelerated lead times.
• Hangar One Avionics saves 30 minutes per part using part inspection software which makes traceability for FAA compliance easier.

Hawk Ridge Systems recommends the Markforged FX10 and FX20 and the HP Multi-Jet Fusion 5200 as the best-in-class 3D printers for aerospace and defense organizations. These printers are used by companies like Boeing, Cabin Management Solutions and Ascendance Flight Technologies.

Additive manufacturing helps the propulsion and space launch industry by offering the ability to consolidate multiple subcomponents into a single 3D-printed component.

This consolidation not only reduces the costs of manufacturing, but also contributes to weight reduction and improved system performance. By leveraging additive manufacturing and consulting services, aerospace manufacturers can optimize their production processes and achieve significant cost savings.

Implementing additive manufacturing can result in a strong return on investment (ROI) for aerospace manufacturers. By reducing costs, improving efficiency and enhancing performance, additive manufacturing offers significant financial advantages for aerospace and defense companies.

One of the key advantages of additive manufacturing in aerospace and defense is the ability to produce lightweight brackets. By leveraging advanced direct metal printing and topological optimization, aerospace manufacturers can design highly complex brackets that maintain or even improve material strength while reducing operational costs. This not only enables greater fuel efficiency, but also contributes to overall weight reduction, fewer bolted and welded joints, and improved system performance.

Traditionally, investment casting patterns required expensive injection molding tooling. However, additive manufacturing offers a cost-effective alternative by enabling the production of 3D printed molds in a fraction of the time and cost. Aerospace parts manufacturers can now move directly from CAD to casting patterns, with fewer design limitations and the ability to create hollow patterns with greater design complexity. This advancement in additive manufacturing technology accelerates production timelines and reduces costs.

Additive manufacturing has been primarily limited to non-essential aerospace parts such as interior components where mechanical stresses are minimal. But with advances in metal 3D printing, additive manufacturing has become one of the most significant aerospace manufacturing technologies. It enables aviation companies to leverage low-volume production runs cost-effectively
