Abstract
A method, apparatus, and program for additive manufacturing. The additive manufacturing method may include solidifying at least a portion of a first layer (601) of build material (416) within a first scan region (902A). At least one of a build unit (400) and a build platform (310) may be moved to solidify at least a portion of the first layer (601) of build material (416) within a second scan region (902B). A second layer (602) of build material (416) may be provided over at least a portion of the first scan region (902A) and the second scan region (902B). A second layer (602) of build material (416) may be solidified within at least a portion of the third scan region (902C), the third scan region (902C) may at least partially overlap and may be offset with relation to the first scan region (902A).
