Materials for the defense industry in additive manufacturing

Key technology in the defense industry

In recent years, additive manufacturing (AM) has made enormous progress and has become an indispensable part of many industries. Metal printing in particular has established itself as a key technology and is also playing an increasingly important role in the defense industry. But what makes this technology so attractive for the military sector?

Case studies

Spare parts printed locally

A key problem for military operations is the supply of spare parts. Thanks to metal printing, these can be produced directly in operational production units, which reduces logistical challenges and minimizes downtime.

Customized protective equipment

Metal printing is also used to manufacture individual protective vests and helmets with integrated metal reinforcements. These items of equipment can be adapted not only to the anatomy of the wearer, but can also be made with particularly light yet strong material structures.

Manufacturing complex weapon systems

Metal printing makes it possible to produce highly complex components for modern weapon systems. From small precision parts to large components such as gun barrels or armor, almost anything is possible. These parts can be designed to be lighter, stronger and more durable.

Key materials for metal printing

The defense industry uses numerous high-strength and resistant metal alloys that are suitable for additive manufacturing. Here are some of the most important:

• Titanium alloys (e.g. Ti-6Al-4V): Excellent strength-to-weight ratio, high corrosion resistance and biocompatibility.
• Aluminum alloys (e.g. AlSi10Mg): light, good mechanical properties and corrosion resistance. Often used for aerospace applications.
• Stainless steel (e.g. 1.4404): high strength and corrosion resistance, ideal for use in harsh environments.
• Nickel-based alloys (e.g. Inconel 718): Heat-resistant, corrosion-resistant and suitable for high-temperature applications.
• Cobalt-chromium alloys: Extremely hard and wear-resistant, often used for armor and protective materials.
• Copper alloys: Good electrical and thermal conductivity, often used in electronic components for military applications.

Future

Additive manufacturing has the potential to fundamentally change the defense industry. As printing technologies and materials continue to develop, even more high-performance components can be produced. In particular, hybrid approaches in which printed metal parts are combined with conventionally manufactured components could further increase efficiency.

Furthermore, research into new metal alloys and printable composite materials will further expand the fields of application. The integration of artificial intelligence into the printing process could also lead to even more precise and reliable components.

Our experience

We have already gained extensive experience in the application of additive manufacturing in various military areas. Here are some examples:

• Spare parts for vehicles: The rapid availability of printed metal components reduces downtime and improves operational readiness.
• Metal parts for weapon systems: Complex components with high precision and stability are successfully produced for various weapon systems.
• Plastic components (PA12) for military drones: Lightweight, durable polyamide parts improve the performance and flexibility of modern drone systems.
• Further applications: From individual protective parts to electronic housings, we have realized a wide range of other components using additive manufacturing.
