Eplus3D, a leading global provider of metal additive manufacturing (AM) solutions, has supported Young-Will Aerospace in completing laser powder bed fusion process validation for a nickel-copper alloy using the EP-M400 metal PBF system. Through process parameter development and scanning strategy optimization, the project achieved crack-free forming of nickel-copper alloy components. The printed parts reached a tensile strength of 570 MPa, representing an 18% improvement compared with conventionally forged parts.
This result not only demonstrates the formability potential of nickel-copper alloys in metal additive manufacturing, but also highlights the value of EP-M400 in special alloy process development. For aerospace applications, material performance, structural integrity, and manufacturing reliability often determine whether a component can withstand complex operating conditions. With a stable industrial metal additive manufacturing system, Eplus3D helped support the transition of this high-value alloy from material potential toward a validated manufacturing route.
From Printability to Process Validation
Nickel-copper alloys are known for corrosion resistance, stable medium-temperature strength, and good processability, making them suitable for demanding aerospace-related applications such as fuel pipelines, hydraulic components, landing gear parts, aircraft engine combustion chambers,fasteners, rocket engine pipe joints, and sealing parts.
For metal additive manufacturing, however, material potential is only the starting point. Nickel-copper alloys require careful control of crack formation, elemental segregation, part density, and mechanical performance during the laser powder bed fusion process. Although copper segregation at grain boundaries is difficult to avoid completely, its impact can be reduced through precise process control.
This is where the value of EP-M400 was reflected in the project. By supporting the coordinated optimization of equipment capability, process parameters, and scanning strategy, EP-M400 helped establish a stable process foundation for nickel-copper alloy additive manufacturing.

EP-M400 Supports Nickel-Copper Alloy Process Window Development
In this project, Young-Will Aerospace needed to validate a laser powder bed fusion process route for aerospace-oriented nickel-copper alloy components. Eplus3D supported the project with the EP-M400 system, which served as the process development and part manufacturing platform.
Using the EP-M400 system, the team optimized process parameters and scanning strategies around the forming characteristics of the nickel-copper alloy, gradually establishing a stable processing route for the material. As a result, the project successfully produced crack-free nickel-copper alloy components and achieved a tensile strength of 570 MPa, 18% higher than that of conventionally forged parts.

This result was supported by the industrial capability of EP-M400. Developed by Eplus3D for medium-to-large metal part production, which offers a build chamber of 400 × 400 × 450 mm, up to six lasers, and a maximum build rate of 210 cm³/h. With its build capacity, flexible laser configuration, and high productivity, EP-M400 provides a stable platform not only for complex structural parts and batch production, but also for special alloy process development.

From Process Validation to Complex Structural Applications
For aerospace fluid, sealing, and low-temperature-related components, conventional manufacturing often involves multiple machining, welding, and assembly steps. The more manufacturing steps involved, the greater the need to manage structural complexity, joint reliability, and potential leakage risks.
LPBF provides a new manufacturing route for these applications. It gives nickel-copper alloys the opportunity to be formed into integrated complex structures, supporting future development of fuel pipe joints, valve components, sealing structures, and low-temperature storage and transfer-related parts.
The EP-M400-based validation was more than a single material printing trial. It established a process foundation by matching powder behavior, equipment capability, process window, scanning strategy, and final part performance. In doing so, the project connected material potential, application requirements, and manufacturing feasibility, moving nickel-copper alloy from its potential as a material toward proven process feasibility.
This also reflects Eplus3D’s system value in special alloy application development. Through industrial metal additive manufacturing equipment and continuously optimized process routes, Eplus3D helps customers turn material potential into a more concrete manufacturing path, supporting the development of complex structural parts in high-value industries such as aerospace, energy, and chemical engineering.

Further Expansion for Aerospace Applications
As aerospace systems place higher requirements on structural integration, material reliability, and manufacturing efficiency, classic alloys such as nickel-copper alloys are gaining new application opportunities.
Nickel-copper alloys show potential in areas such as liquid hydrogen storage and transfer systems, rocket engine fuel pipe joints, and valve sealing components. Metal additive manufacturing is expected to further promote their use in complex structural parts.
For Eplus3D, this case once again shows that the value of metal additive manufacturing is not limited to printing parts. It lies in helping customers complete the critical transition from material validation and process development to application exploration.
Moving forward, Eplus3D will continue to support high-value manufacturing fields such as aerospace, helping more special alloy materials move toward complex structural applications and providing customers with reliable, scalable metal additive manufacturing solutions.
