1. An additive manufacturing system for processing a material layer into a workpiece, the system comprising:
a plurality of modules, each module having a fiber tip, a lens, and a micro-scanner, the micro-scanner being configured to selectively change a position of at least one of the fiber tip and the lens in at least one dimension;
a laser source being configured to selectively provide laser power to the fiber tips of the modules; and
one or more processors in operable communication with the modules and the laser source, the one or more processors being configured to:
determine, for each of the modules, a set of cell-specific operations configured to process the material layer in a cell of a build surface for the workpiece that corresponds to that module; and
operate, for each of the modules, the laser source and the micro-scanner based on the set of cell-specific operations to process the material layer within the corresponding cell.
