Introduction
In recent years, 3D printing technology has revolutionized the manufacturing industry, offering a host of benefits such as reduced costs, increased customization, and faster production times. One company at the forefront of this technological advancement is Australian metal 3D printer manufacturer SPEE3D. They have recently launched their new Expeditionary Manufacturing Unit (EMU), a mobile additive manufacturing system optimized for defense applications. This article aims to provide a comprehensive overview of the SPEE3D EMU, including its background, capabilities, and benefits for defense applications.
Overview of SPEE3D
Background
SPEE3D is an Australian company specializing in metal 3D printing. They have developed innovative technology that utilizes a process known as cold spray 3D printing. This method involves using compressed air to propel metal particles at supersonic speeds, causing them to bond with the surface and rapidly build up layers to form a solid object. The cold spray 3D printing technique offered by SPEE3D has numerous advantages over traditional manufacturing methods, such as reduced production times, improved design freedom, and the ability to create complex geometries.
3D Printing Technology
3D printing, also known as additive manufacturing, involves creating objects by adding layer upon layer of material until the desired shape is achieved. This technology has gained popularity in various industries due to its versatility and potential for cost savings. In the case of SPEE3D, their cold spray 3D printing technology offers several unique features that set it apart from other additive manufacturing techniques.
Unlike traditional 3D printing methods that rely on heat to melt and fuse the layers of material together, cold spray 3D printing uses supersonic speeds to bond metal particles together without the need for high temperatures. This process not only speeds up production times but also allows for the use of a variety of metals, including aluminum, copper, and steel.

Expeditionary Manufacturing Unit (EMU)
Description
The Expeditionary Manufacturing Unit (EMU) developed by SPEE3D is a cutting-edge mobile additive manufacturing system designed specifically for defense applications. It combines the company’s XSPEE3D cold spray 3D printer with their SPEE3Dcell post-processing unit, creating a comprehensive solution for rapidly producing metal spare parts in remote locations.
The EMU is a self-contained unit housed within a transportable container, allowing it to be easily deployed to various locations. It is equipped with all the necessary equipment and components to carry out the entire 3D printing and post-processing process, minimizing the reliance on external infrastructure.
Optimization for Defense Applications
One of the main advantages of the EMU is its optimization for defense applications. Traditional supply chains for military spare parts often involve lengthy procurement processes, delays in shipping, and reliance on imports. The EMU overcomes these challenges by enabling defense forces to manufacture time-critical parts on-site.
By having the ability to produce spare parts in the field or on naval vessels, military forces can significantly reduce their dependence on external suppliers, ensuring they have access to essential equipment even in remote or hostile environments. This enhances operational readiness and reduces potential vulnerabilities in the supply chain.
Benefits of EMU for Defense Applications
Overcoming Supply Chain Challenges
The ability to manufacture spare parts on-site offers several benefits for defense applications. Firstly, it reduces the dependence on external suppliers, eliminating the potential delays and challenges associated with traditional supply chains. Regardless of the location or operational scenario, the EMU ensures that the necessary spare parts can be produced quickly and efficiently, minimizing the impact on critical missions and operations.
Furthermore, the EMU provides a solution to the logistical challenges faced by defense forces. Transporting spare parts to remote or overseas locations can be a time-consuming and costly endeavor. By having the ability to produce parts on-demand, the EMU significantly reduces the need for shipping, allowing resources to be allocated more efficiently.
On-site Production of Time-Critical Parts
In military operations, time is often of the essence. The EMU addresses this requirement by enabling on-site production of time-critical parts. Instead of waiting for parts to be sourced and shipped, defense forces can now have immediate access to essential equipment.
This capability is particularly crucial in remote or isolated environments where the availability of spare parts may be limited. The EMU ensures that military personnel have the tools and resources they need to carry out their mission effectively, reducing downtime and enhancing operational efficiency.
Development and Testing
To ensure the reliability and effectiveness of the EMU, SPEE3D has conducted rigorous testing and military trials with various defense forces.
Military Trials with US Navy
The EMU has undergone extensive military trials with the US Navy, validating its capabilities and performance in naval environments. The trials involved testing the system’s ability to produce and deliver critical spare parts while onboard naval vessels. The positive results of these trials have led to the adoption of the EMU by the US Navy, enhancing their operational readiness and reducing reliance on external suppliers.
Military Trials with Australian Army
The Australian Army has also conducted military trials with the EMU, evaluating its suitability for land-based operations. These trials focused on the system’s performance in remote and rugged environments, where the availability of spare parts can be a significant challenge. The EMU demonstrated its ability to produce high-quality parts quickly and effectively, ensuring the Australian Army’s operational capabilities remain uninterrupted.
Military Trials with British Army
The British Army has also recognized the potential of the EMU and has carried out military trials to assess its suitability for their operations. These trials focused on the system’s ability to produce large-scale, metal sand casted-equivalent parts, which are commonly used in military equipment. The EMU’s performance in these trials has been highly promising, showcasing its potential to revolutionize the logistics and maintenance capabilities of the British Army.
