An Overview of Additive Manufacturing in Aerospace and Defense

Additive manufacturing, often known as 3D printing, has captured the imagination of engineers and technologists worldwide. Initially seen as a novelty, it has matured significantly, making inroads into serious, high-stakes industries like aerospace and defense.

The Growth Trajectory

From its infancy to what’s now considered its “adolescence,” additive manufacturing has come a long way. The aerospace and defense sectors, in particular, have moved from experimental stages to limited applications. Yet, the goal remains mass adoption. This transformation is accelerating thanks to innovative technologies and strategic partnerships that aim to overcome existing challenges.

The Spotlight on EBM Technology

During our interview at RAPID + TCT 2024, Chris Schuppe shone a spotlight on electron beam melting (EBM) technology. He elaborated on its significant advantages for aerospace and defense applications, given its unique properties and capabilities.

Why EBM?

EBM uses an electron beam to melt and fuse material powder layer by layer, creating highly detailed and robust parts. The process happens in a vacuum or lower-pressure environment, conducive to excellent material properties. This makes it ideal for high-stress, critical applications like jet engine components and defense equipment.

What EBM Brings to the Table

EBM’s main value proposition lies in its ability to produce parts with superior mechanical properties, reduced residual stresses, and excellent geometric accuracy. These attributes are essential in aerospace and defense, where even the smallest error can lead to catastrophic failures.

New Product Introductions and Innovations

Colibrium Additive unveiled new EBM 3D printer models and an updated version of their additive manufacturing software. These new products promise to take support-free 3D printing to the next level, driven by technological innovations like Point Melt.

The New EBM Models

The latest models aim to offer higher productivity without compromising quality. They come with enhanced capabilities for precise melt pool control, enabling the production of complex parts with fewer supports.

The Role of Point Melt

Point Melt is a key innovation that Schuppe introduced. This technology improves control over the melt pool, making it easier to produce intricate parts without the need for additional support structures. The impact on both material efficiency and manufacturing speed is substantial.

Industry Challenges: Certification and DfAM

While the technology is groundbreaking, it doesn’t come without its challenges. Schuppe emphasized the significant hurdles that still need to be overcome, such as certification and the advancement of Design for Additive Manufacturing (DfAM).

Certification Woes

Achieving certification for 3D-printed parts is often a drawn-out process. Regulatory bodies require rigorous testing and validation to ensure that these parts meet the same stringent standards as their traditionally manufactured counterparts.

Designing for Additive Manufacturing

DfAM involves optimizing parts specifically for 3D printing. Unlike traditional manufacturing methods, additive manufacturing allows for more complex geometries and internal structures. However, designing for these methods requires a shift in mindset and substantial retraining for engineers.

Addressing These Challenges

Overcoming these barriers often involves strategic partnerships between technology providers and end-users. Working closely with regulatory bodies from the onset can also streamline the certification process.

Strategic Partnerships for Success

Colibrium Additive’s collaboration with GE Aerospace and various programs with the U.S. Department of Defense, including Pacer Edge, stands as a testament to the power of strategic partnerships.

Colibrium and GE Aerospace

The partnership aims to integrate advanced EBM capabilities into GE Aerospace’s manufacturing processes. This collaboration promises to result in parts that are lighter, stronger, and more energy-efficient.

Pacer Edge and DoD Collaborations

The Pacer Edge program exemplifies the synergy between Colibrium Additive and the Department of Defense (DoD). The initiative aims to produce spare parts for aging military equipment, thus enhancing operational readiness. This strategic partnership is instrumental in mitigating supply chain risks and ensuring that critical systems remain operational.

Overcoming Barriers to Adoption

Despite the progress, there are still barriers to widespread adoption in the aerospace and defense sectors. These primarily revolve around certification, consistent part quality, and the importance of in-situ monitoring.

Certification: A Hurdle to Leap

Getting a part certified is time-consuming and costly. The long lead times can deter companies from making significant investments in additive manufacturing technologies.

Part Quality Consistency

Achieving consistent quality across batches is another major challenge. Variations in the manufacturing environment can result in differences in material properties and part performance.

The Role of In-situ Monitoring

In-situ monitoring technologies are crucial for real-time quality assurance. By monitoring the manufacturing process from start to finish, these systems can detect deviations and prompt corrective actions, ensuring consistency and quality.

Technological Advances to the Rescue

The future looks promising, with continuous technological advancements driving the industry forward. Innovations like Point Melt and support-free 3D printing are paving the way for higher productivity and improved quality.

The “Laser Wars”

The industry is witnessing what Schuppe referred to as “laser wars,” a trend where various technologies compete to offer the most efficient and effective solutions. While the competition is fierce, it drives innovation, encouraging companies to push the boundaries of what’s possible.

A Balanced Approach: Productivity and Quality

Schuppe advocates for a balanced approach that doesn’t sacrifice quality for the sake of productivity. This philosophy is crucial for the aerospace and defense sectors, where parts must meet stringent performance criteria.

Future Outlook and Trends

As we look to the future, several trends and developments promise to shape the landscape of additive manufacturing in aerospace and defense.

Increased Automation

Automation is expected to play a larger role, reducing human intervention and minimizing errors. From automated design software to robotic arms handling parts, the industry is moving toward more automated, efficient processes.

Greater Material Diversity

Advancements in material science will lead to a broader range of printable materials. This diversity will enable the creation of parts with unique properties tailored to specific applications.

Sustainability Focus

Sustainability is becoming increasingly important. Additive manufacturing inherently reduces waste compared to traditional methods, but further advancements will focus on recycling and reusing materials.

Global Collaborations

International partnerships and collaborations will be crucial in addressing global challenges and driving innovation. By sharing knowledge and resources, companies can overcome barriers more effectively and accelerate the development of new technologies.
