Abstract
A magnetic locking system for securing a printing platform to a print arm within a three-dimensional (3D) printing system is provided. First and second magnets are configured with an end of the print arm, and a locking plate formed of a material that is attracted to magnetic fields is configured with the printing platform. The magnets are configured with a moving assembly that toggles the magnets with respect to one another between a first position and a second position, thereby varying the overall magnetic force generated by the magnets. When in the first position, the magnet applies an attractive magnetic force to the locking plate that secures the printing platform. When in the second position, the attractive magnetic force is reduced or eliminated, and the printing platform is released. The system provides a consistent and repeatable magnetic locking force between a printer arm and a printing platform.
