Revolutionizing Aerospace & Defense Through 3D Printing
Additive manufacturing offers clear benefits to the aerospace industry including improved design, reduced weight via topological optimization, enhanced performance, and more efficient production processes. Aerospace components often require intricate and complex shapes that are difficult or impossible to achieve using traditional manufacturing methods. AM allows the creation of highly intricate structures, such as generative designs for lightweighting, that can optimize aerodynamics and thermal management.
The defense sector can face supply chain disruptions due to geopolitical issues or emergencies. AM reduces lead times by eliminating the need for some tooling and enabling on-demand production. AM also offers the unique ability to produce critical components on-site or near the point of use, reducing dependence on external suppliers.
Better Surface Finish. Better Performance.
Aerodynamic efficiency and optimal thermal transfer between a source and fluid are key benefits additive manufacturing provides to applications in the aerospace industry. The FormUp 350 is capable of using a finer particle PSD and this coupled with our roller recoater technology allows for design complexity while achieving best-in-class surface finish, as printed. This is important for aerospace applications because the smooth finish facilitates and optimizes airflow, thereby maximizing heat transfer efficiency. Optimal surface finish also important because reduces surface irregularities, such as roughness, burrs, or surface defect, improving the fatigue strength and thermal integrity for many aerospace applications.
Topological optimization is often used to aid in weight reduction for aerospace applications. AddUp is experienced in optimizing parts for AM using this process. Additionally, AddUp’s technology allows for extreme overhang geometry while limiting the number of support structures needed. This greatly reduces post-processing required for support removal and subsequently overall production time.
In aerospace, manufacturers are constrained by rigorous qualification requirements. Safety and reliability are paramount, even the smallest details can have significant impact and dramatic consequences. AddUp is the experienced partner manufacturers can count on. Our experts are knowledgeable on qualifications and certifications required for the aerospace industry and can speed up the process of qualifying your part applications with our ISO certified facilities. The AddUp suite of in-process monitoring software directly answers the needs of the aerospace industry by providing confidence in part quality through every stage of the manufacturing process.

Key Applications in Aerospace & Defense
AddUp has expertise and experience optimizing aerospace applications to maximize performance while being safer and more reliable to meet the needs of such a highly regulated industry. Utilizing a fine powder with a roller recoater for controlled and uniform powder deposition, the FormUp 350 can achieve superior surface finishes to maximize heat transfer, improve engine performance, enhance fuel efficiency, reduce drag, and ensure the longevity and reliability of critical components.
As an expert of two different additive technologies, AddUp has the unique ability to optimize aerospace applications using both Powder Bed Fusion (PBF) and Directed Energy Deposition (DED). Where PBF is ideal for heat exchangers with thin walls and fine features, DED is ideal for larger scale propulsion components such as rocket nozzles.
Heat Exchangers
A key application in the aerospace industry, a heat exchanger is a device designed to transfer heat between two or more fluids that are at different temperatures. Best-in-class surface finish as printed, as low as 4um Ra, and fine feature resolution <200um from the FormUp 350 facilitates and optimizes airflow and maximizing heat transfer efficiency.
Impellers and Blades
Impellers are rotating components designed to increase or decrease the flow and pressure of a fluid in an engine. They are excellent applications for additive manufacturing thanks to the ability to create highly complex and customized blade designs to improve fluid dynamics, performance and efficiency. A smooth surface is essential for optimal performance in these applications. Superior surface finish from the FormUp 350 minimizes turbulence, pressure losses, and energy wastage. This enables optimal gas flow, which translates into improved engine power, fuel efficiency, and overall performance.
Propulsion Components
A propulsion component, such as a rocket nozzle, is used to generate thrust and propel an object forward. These types of applications require a performance material to ensure durability and longevity. AddUp’s DED technology is ideal for manufacturing propulsion components because it allows for the creation of near-net shapes with optimized geometry on a large scale. AddUp DED machines come equipped with house-designed nozzles for better meltpool control and precision.
Satellite and Antenna Supports
Traditional manufacturing methods like CNC machining have limitations in achieving intricate and lightweight designs without sacrificing structural rigidity. AM allows for design freedom, crucial for optimizing satellite components to meet specific performance, weight, and size requirements. AddUp’s fine powder and roller recoater allow for design complexity while achieving best-in-class surface finish, as printed, and limiting the number of supports required.
Pumps and Turbomachinery
Pumps are used to transfer fluids from one location to another by increasing the fluid’s pressure and flow rate. Additive manufacturing offers numerous advantages for turbomachinery including design flexibility and improved performance. Some of these applications require complex assemblies which can be consolidated into a single component using AM, reducing overall production costs. AM is also used for these types of applications to optimize internal structures leading to more efficient parts requiring less energy consumption.
Manifolds
A manifold is a component used for industrial applications to distribute, collect, or control the flow of fluids, gases, or other substances. Additive manufacturing allows for lightweight yet strong designs to optimize performance for these applications. AM also enables the integration of functional features directly into the manifold, such as valves, sensors, connectors, and brackets. This reduces the need for additional assembly steps and potential points of failure.
