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 for generating fusion energy, much like the process powering stars.This innovative design represents a significant reduction in cost and time compared to […]
