Closed-loop control developed for additive manufacturing systems

Sciaky Inc., a subsidiary of Phillips Service Industries Inc., has developed the patented IRISS℠ (interlayer real-time imaging and sensing system) closed-loop control to power its Electron Beam Additive Manufacturing (EBAM™) systems.

The closed-loop control provides consistent process control for part geometry, mechanical properties, microstructure, and metal chemistry for large-scale, 3-D printed parts. This technology monitors the metal deposition process in real time and makes adjustments to the process parameters that compensate for variation throughout the build process.
