Engineers use unique 3D printed models for assembly of nuclear fusion device

Engineers at the Princeton Plasma Physics Laboratory (PPPL) in the U.S. are preparing for the assembly of the fusion research device National Spherical Torus Experiment-Upgrade (NSTX-U) expected to begin operations in 2026.  To ensure precise alignment of components, they have created over 50 3D printed prototypes. Central to the NSTX-U is a magnet bundle that […]
