The Princeton Plasma Physics Laboratory (PPPL) has developed a small, experimental nuclear fusion reactor , constructed largely with 3D-printed and off-the-shelf parts. This compact reactor—roughly the size of a kitchen table—uses a glass tube surrounded by 3D-printed nylon and nearly 10,000 rare-earth magnets to contain superheated plasma, the basis […]
