Custom Aerospace Fasteners with Additive Manufacturing
Aerospace fasteners serve as critical joining components that secure structural assemblies and maintain load paths across a wide variety of aircraft systems. As manufacturing demands continue to evolve for such components, additive manufacturing is increasingly being explored as a complementary approach to traditional machining and forming methods. In this blog, we will explore how additive manufacturing can improve aerospace fastener design and production, examine the primary processes used to create custom components, and review key constraints that procurement teams should consider when evaluating such solutions.
How Does Additive Manufacturing Improve Fastener Production?
For procurement teams evaluating where additive manufacturing aerospace fasteners can offer value, several distinct advantages should be considered, including:
- Design Flexibility: Some additive manufacturing processes support the development of aircraft fasteners with specialized geometries that are difficult or impractical to achieve with conventional machining processes.
- Lead Time Reduction: By reducing reliance on dedicated tooling and setup processes, additive manufacturing can shorten development and production timelines for certain fastener designs.
- On-Demand Production: Digital manufacturing workflows enable fasteners to be produced in smaller quantities as needed, allowing procurement teams to reduce inventory burdens.
- Material Efficiency: Additive manufacturing processes can reduce excess material waste when working with high-value aerospace alloys, as material is deposited only where needed rather than removed from a larger stock.
How Is Powder Bed Fusion Used To Fabricate Aircraft Fasteners?
Powder bed fusion (PBF) is among the most widely recognized additive manufacturing methods employed for the development or limited production of aircraft fasteners. In this approach, high-energy sources like lasers or electron beams selectively fuse fine metal powders layer by layer, allowing for the creation of complex geometries that are often difficult or resource-intensive to achieve through traditional manufacturing techniques. To ensure that resulting components meet required performance criteria, produced fasteners typically undergo controlled build parameter management and may be subject to post-processing steps like heat treatment or hot isostatic pressing.
What Key Constraints Affect the Use of Additive Manufacturing for Aerospace Fasteners?
While additive manufacturing offers several advantages, its use for aerospace fasteners is often shaped by a range of technical and purchasing constraints. One key challenge lies in certification and qualification processes, as some components produced through additive methods require additional testing, documentation, and approval under established regulatory frameworks before they can be accepted for flight-critical applications. In addition, variability in material properties or surface finish can arise if quality controls are not tightly managed across production batches.
