Abstract: 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.

Abstract: 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.

Abstract: A method, apparatus, and program for build surface mapping and recovery for additive manufacturing. The method may include fabricating an object by additive manufacturing wherein the topology of a build surface is determined. An additive manufacturing process may be modified based on the topology determination. The topology of the surface may be determined by marking the surface with a first mark using a converging energy source; determining a dimension of the mark using a camera; and determining a height of the first mark based on the dimension of the mark.
