Sciaky, Inc., a subsidiary of Phillips Service Industries, Inc. based in Chicago, Illinois, USA, has announced it has introduced a patented closed-loop control system for its Electron Beam Additive Manufacturing (EBAM) systems. The Interlayer Real-time Imaging & Sensing System (IRISS) provides consistent process control for part geometry, mechanical properties, microstructure and metal chemistry for large-scale AM parts.
This innovative closed-loop control, which is claimed to be exclusive to Sciaky EBAM systems, monitors the metal deposition process in real time and makes adjustments to the process parameters that compensate for variation throughout the build process.
Sciaky’s EBAM systems utilise wire feedstock which is available in a variety of metals such as titanium, tantalum, niobium, tungsten, molybdenum, Inconel, aluminium, stainless steels, nickel alloys, and more. Sciaky can produce parts ranging from 203 mm to 5.79 meters in length.
EBAM is currently the fastest deposition process in the metal Additive Manufacturing market, with gross deposition rates ranging from 3.18 to 9.07 kg of metal per hour. The process also allows the use of a dual wire-feed option, where it combines two different metal alloys into a single melt pool to create custom alloy parts or ingots. In addition, you can change the mixture ratio of the two materials to create graded parts or structures.
“Sciaky’s IRISS closed-loop control is in a class by itself,” stated Mike Riesen, General Manager of Sciaky, Inc. “It is a big reason why EBAM is the most advanced metal Additive Manufacturing processes in the market for large-scale parts.”
