Abstract: The present disclosure generally relates to powder packing for additive manufacturing (AM) methods and systems. Conventional powder packing methods are manual and non-standardized, and they result in operator fatigue and potentially product inconsistencies. Powder packing according to the present disclosure improves standardization and reduces turnaround time, with the potential to lower the cost of AM.

Abstract: The present disclosure relates generally to methods and apparatuses for additive manufacturing using reduced amounts of powder-based built materials. Such methods and apparatuses mitigate several drawbacks of conventional power-based methods, including high powder overhead, increased costs, ergonomic strain on machine operators, health risks, and risk of short powder feeds.

Abstract: A method, apparatus, and program for calibrating an additive manufacturing apparatus. In one aspect, a method is disclosed for calibrating an additive manufacturing apparatus. The method includes forming a first solidified portion within a first scan region, wherein the solidified portion within the first scan region is formed by irradiating a build material while a build unit is in a first location. The method further includes forming a second solidified portion within a second scan region, wherein the second solidified portion within the second scan region is formed by irradiating a build material while a build unit is in a second location different from said first location. An alignment of the additive manufacturing apparatus determined based on the detected alignment of the first solidified portion and the second solidified portion.
