The present disclosure generally relates to methods and apparatuses for additive manufacturing with improved powder distribution capabilities. Specifically, the methods and apparatuses of the present disclosure incorporate powder distribution vanes to improve the lateral deposition of powder from a hopper. Such methods and apparatuses have the potential to reduce powder overhead costs, mitigate associated health and environmental risks, and increase manufacturing efficiency.

Modified frame and recoating system

A method, apparatus, and program for additive manufacturing. In one aspect, the method and program comprises forming an at least partially solidified portion within a first scan region by irradiating a build material at a first energy density value along a first irradiation path. A second at least partially solidified portion is formed within a second scan region that is spaced with respect to the first scan region, wherein the solidified portion within the first scan region is formed by irradiation a build material at a second energy density value along a second irradiation path. The space between the first scan region and the second scan region is at least partially solidified by irradiating a build material at a third energy density value that less than the first energy density value and the second energy density value.

Scanning strategy for perimeter and region isolation

A method of characterizing gas flow within a housing includes: positioning one or more gas flow sensors in the housing; introducing a gas flow into the housing; using the one or more gas flow sensors to generate two or more gas flow measurements at spaced-apart locations within the housing; and recording the two or more measurements to create a gas flow map.
