Abstract: Systems, apparatus, and methods for weld tapering at a trailing edge using time multiplexing are disclosed. Systems, apparatus, and methods for control of an electron beam for welding using time multiplexing are disclosed. An example apparatus includes memory and at least one processor to execute instructions to at least: in a first portion of a line of an object being formed, control an energy beam at a first position at a first time to form a weld from a powder; and in a second portion of a line of the object being formed, control the energy beam to perform a dispersion sweep at a second position at a second time.
