Additive Manufacturing Trends in Aerospace Fasteners

Aerospace manufacturing is in a state of perpetual evolution, driven by the dual imperatives of improving quality and production efficiency. While past decades have seen the advent of various technologies and techniques that collectively improve the capabilities of production, the recent rise of additive manufacturing (AM) has emerged as a particularly revolutionary force. This is especially true for the vast array of fasteners that find use across aircraft and aerospace assemblies, with additive manufacturing now being common for the basic creation of flight-critical hardware.

For those who are less familiar with additive manufacturing and the impact it has on aerospace fasteners and other hardware, be sure to read on as we examine current trends. With this knowledge, you can better understand current shifts across the market and capitalize on emerging supply options that present improved quality and interchangeability.

What Is Additive Manufacturing?

Commonly referred to as 3D printing in many commercial and consumer spaces, additive manufacturing is a production process that centers around the idea of constructing individual components layer-by-layer from a digital CAD file. Unlike traditional, subtractive methods of production that involve a solid billet being carved and shaped to create a finalized item, additive manufacturing removes all material waste by only using what is necessary to establish the end product.

Notable Characteristics of Additive Manufacturing

Layer-by-Layer Fabrication: As stated before, the defining element of additive manufacturing is that parts are constructed through the sequential deposition of materials. While requiring specialized equipment and CAD files, this technique eliminates the need for many complex tools and molds.
Material Versatility: Many additive manufacturing systems can handle aerospace-grade titanium, superalloys, and high-performance polymers like PEEK for tailoring the mechanical properties of end products.
Digital Integration: To support engineers creating next-gen designs, additive manufacturing allows assets created in 3D modelling software to be directly translated into an equivalent item.
Process Repeatability: From AI-augmented sensors to monitor build quality in real-time to advanced electromechanical assembly parts for precision actuation and movement, many additive manufacturing systems offer a level of repeatability that ensures finalized fasteners and hardware meet necessary flight-safety standards.

How Is Additive Manufacturing Changing Aerospace Fastener Design?

While additive manufacturing is still limited to specific use cases at this time, its permeation into many standard production processes has introduced new design possibilities that were difficult to achieve through conventional methods. For example, some of the most notable developments in aerospace fastener design that are being driven by this additive manufacturing include:

Optimized Load Distribution: With the 3D software mentioned before, engineers can experiment with geometry changes that distribute stress more evenly across fastener bodies, helping end-products reduce localized structural stress.
Weight Reduction Opportunities: Layer-based production allows unnecessary material use to be avoided while preserving structural integrity, which can improve weight efficiency in performance-sensitive assemblies. For example, lattice structures and internal hollowing can result in fasteners that uphold reliable integrity while being half as heavy as their standard counterparts.
Material Integration With Advanced Alloys: Advanced alloys like titanium are often desirable for aerospace fasteners with their high strength and corrosion resistance, though they tend to be more expensive than other options. Through additive manufacturing and reduced material use, manufacturers can lower production costs for AM titanium aerospace fasteners and pass along savings to customers.
Specialized Assembly Applications: Additive fasteners may support niche configurations when conventional geometries are unable to fully match structural requirements.

With these various benefits, additive manufacturing continues to take off for the production of 3D printed aerospace fasteners and other core assembly items.

What Aerospace Fastener Buyers Should Keep in Mind

With the market facing an influx of options for aerospace fasteners that were produced through additive manufacturing techniques, teams looking to address project requirements should seek to determine whether such solutions are fitting for operations before making any investment. This generally comes down to an analysis of whether desired listings align with application requirements and constraints, as well as addressing any concerns for budget and timeliness. For a typical buyer looking to engage in aerospace sourcing, important considerations to keep in mind will include:

Specification Alignment: Confirm that all fasteners produced through additive manufacturing meet any required structural, dimensional, and installation specifications for their intended applications. While such hardware can even surpass the capabilities of conventional options, others may feature hollow designs or other characteristics that void their feasibility in the face of demanding requirements.
Material and Process Traceability: Just like any other fastener, hardware made through additive manufacturing should always come complete with traceability records and documentation on materials to satisfy compliance concerns.
Availability and Lead Time: Sourcing decisions often depend on whether any required fastener can be obtained within a practical procurement timeline, where the benefits offered by additive manufacturing may be outweighed in the face of longer lead times.

With careful evaluation of factors like these, buyers can best determine whether or not their operations can benefit from the continued rise of additive manufacturing.
