Systems and methods for additive manufacturing are described. In some embodiments, a method of controlling the one or more laser energy sources of an additive manufacturing system may be based at least in part on a scan angle and/or desired energy density. Systems and methods for controlling melt pool spacing are also described.

Angled scanning of laser arrays in additive manufacturing

Laser control systems and related methods for controlling arrays of lasers are disclosed. A laser control system may include a first controller configured to generate a trigger signal based on a position of a laser array, and a second controller configured to send a firing signal to one or more lasers of the laser array upon receiving the trigger signal. The one or more lasers may be selected based on a desired pattern of laser energy to be formed at a particular position of the laser array.

Laser control systems for additive manufacturing

Aspects described herein relate to additive manufacturing systems and related methods. An additive manufacturing system may include two or more laser energy sources and associated optical fibers. An optics assembly may be constructed and arranged to form a rectangular laser energy pixel associated with each laser energy source. Each pixel may have a substantially uniform power density, and the pixels may be arranged to form a linear array of laser energy pixels on a build surface with no spacing between the pixels. Exposure of a portion of a layer of material on the build surface to the linear array of laser energy pixels may melt the portion of the layer.
