Sciaky, Inc., a subsidiary of Phillips Service Industries, Inc. (PSI) and supplier of electron beam (EB) welding and metal additive manufacturing (AM) solutions, announced that demand for its Electron Beam Additive Manufacturing (EBAM) and EB welding solutions, has not been adversely affected by the global COVID-19 pandemic.
Over the past two months, Sciaky has reported a dozen new projects, ranging from high-level research and development (R&D) projects to production of prototype and production parts, mostly tied to the aerospace industry. Details of these projects are protected by nondisclosure agreements (NDAs), due to their confidential nature.
Many of the EBAM metal 3D printing projects involve a variety of high-value materials, such as titanium, Inconel, niobium, copper-nickel and stainless steel. In addition, the amount of material deposition is particularly high for titanium (1500 lbs. / 680 kg) and copper-nickel (1100 lbs. / 498 kg).
Sciaky’s EBAM metal 3D printing solution is a wire-based direct energy deposition (DED) process. Wire feedstock/raw material is available in titanium, tantalum, tungsten, Inconel, niobium, nickel-copper/copper-nickel, aluminum, molybdenum, zircalloy, and stainless steel. In many cases, wire feedstock is 50% cheaper (or more) than powder feedstock. In addition, wire feedstock is safer and easier to store than powder feedstock (the powder used in aluminum and titanium is known to be highly flammable).
Sciaky’s EBAM systems can produce parts ranging from 8 in. (203 mm) to 19 ft (5.79 m) in length. EBAM is also a fast deposition process with gross deposition rates up to 25 lb. (11.34 kg) of metal per hour. The IRISS –Interlayer Real-time Imaging and Sensing System– is a real-time adaptive control system that can sense and digitally self-adjust metal deposition with precision and repeatability.
