Examples described herein provide a computer-implemented method that includes aggregating data. The method further includes filtering the data to eliminate objects known not to be suitable for additive manufacturing. The method further includes performing machine learning on the data to identify objects suitable for additive manufacturing. The method further includes generating, using additive manufacturing, at least one of the objects identified as being suitable for additive manufacturing.

Identifying candidate objects for additive manufacturing

A method of calibrating a laser of an additive manufacturing system involves processing a test pattern with the laser while varying one or more of laser power and/or scan speed. Thermal energy emitted from the resulting meltpool is measured while processing the test pattern. The power of the laser is calculated using a relationship between volumetric energy density and the thermal emissions, and the laser power is adjusted based on the calculated laser power. An additive manufacturing system for performing such a method may include a laser, a thermal sensor configured to measure meltpool thermal emissions, a processor configured to calculate a laser power based on the measured meltpool thermal emissions of the test pattern, and a controller configured to adjust the laser power based on the calculated laser power.

A process for producing a powder witness coupon including additively manufacturing a container simultaneously with a primary part, filling at least a portion of the container with a feed material employed for the part simultaneously with the additive manufacturing of the primary part, and sealing the container during the additive manufacturing of the primary part. An in-situ feed material powder witness coupon including a container additively manufactured simultaneously with a primary part, and a plurality of individual chambers within the container, at least one of the chambers being removable intact from the container. Further, a method for enhancing examination of feed material in an additively manufactured part including additively manufacturing a container simultaneously with a primary part, capturing feed material, density and environment in the container, and sealing the container.
