US nuclear fusion project uses 3D printing to create a Hollywood-like replica

Engineers at the Princeton Plasma Physics Laboratory are using 3D-printed models to prepare for the assembly of a critical magnet system in their fusion energy device, NSTX-U. The full-scale magnet bundle, currently under construction in Spain, will arrive in fall 2025. The 3D models allow engineers to pre-fit components and cooling systems, reducing risks and accelerating the project timeline. This innovative approach is saving time and money while ensuring a smoother construction phase for this pivotal fusion energy machine.
