1. A magnetic locking system for use in securing a print arm to a printing platform within a three-dimension (3D) printing system, the magnetic locking system, comprising:
a member configured with the printing platform and comprising a material that is attractable to magnetic forces;
one or more magnets configured with the print arm and configurable to apply attractive magnetic force to the member;
a magnet moving mechanism including one or more activation mechanisms, wherein the magnet moving mechanism is configured to repeatably apply a moving charge to repeatably toggle at least one of the one or more magnets between a first position and a second position and provide a repeatable and releasable locking force;
wherein when in the first position, the one or more magnets provide a repeatable first attractive magnetic force with respect to the member, and when in the second position, the one or more magnets provide a repeatable second attractive magnetic force with respect to the member; and
wherein the repeatable first attractive magnetic force holds the member at an interface between the member and the one or more magnets, and the repeatable second attractive magnetic force releases the member from the interface.
