1. An additive manufacturing system for metals, the system comprising:
a. a laser source, for providing a working laser beam;
b. a Digital Mirror Device in optical communication with the laser source, whereby the laser source can propagate the working laser beam along a first laser beam path to the Digital Mirror Device;
c. a control system, in control communication with a memory device; in control communication with a GUI; in control communication with the Digital Mirror Device; in control communication with the laser source; and, in control communication with a stage;
d. the memory device comprising a plurality of image segments of an entire image of an object to be built;
e. the stage comprising a motor and the Digital Mirror Device;
f. wherein the Digital Mirror Device is configured to project the working laser beam in a predetermined pattern along a second laser beam path to a target area, wherein the target area comprises a powder;
g. wherein the predetermined pattern comprises the image segments;
h. the control system comprising instructions, wherein the instructions synchronize the movement of the stage and the projection of the image segments to the target area;
i. whereby the image segments are projected to the target area to deliver the working laser beam in the image of the entirety of the object to be built; thereby building the object from the powder.
