Closed-loop control for metal 3D printing systems

Sciaky, Inc., a subsidiary of Phillips Service Industries, Inc. (PSI) and  provider of metal additive manufacturing (AM) solutions, announced today that it has introduced a patented closed-loop control, called IRISS™, for its industry-leading Electron Beam Additive Manufacturing (EBAM) systems.

IRISS, which stands for Interlayer Real-time Imaging & Sensing System, provides consistent process control for part geometry, mechanical properties, microstructure, and metal chemistry for large-scale 3D printed parts. This innovative closed-loop control, which is 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. EBAM systems utilize wire feedstock, which is available in a variety of metals such as titanium, tantalum, niobium, tungsten, molybdenum, Inconel, aluminum, stainless steels, nickel alloys, and more.

"Sciaky's IRISS closed-loop control is in a class by itself," said 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."

As the most widely scalable metal 3D printing solution on the market (in terms of work envelope), Sciaky's EBAM systems can produce parts ranging from 8 inches (203 mm) to 19 feet (5.79 meters) in length. EBAM is also the fastest deposition process in the metal additive manufacturing market, with gross deposition rates ranging from 7 to 20 lbs. (3.18 to 9.07 kg) of metal per hour. Plus, with a dual wirefeed option, you can combine 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.
