Aerospace Corp. has released a new technical paper based on the results of their independent study of PrintRite3D®’s in-situ monitoring for process optimization and microstructure control in their additive manufacturing process.
In the study, the raw data stream from a commercial in-situ monitoring system based on thermal emission sensing was assessed for its ability to detect laser powder-bed process variations and relate those to physical characteristics of the material and the parts for a nickel-based superalloy.
Variation in sensor data due to part geometry, support structure and build plate location were assessed, showing that the system can detect very fine changes in thermal characteristics, including scanning strategy, laser spot eccentricity, and air flow within the printer. The analysis also showed that nominally identical builds were printed using different laser scanning histories.
