Sciaky sells four EBAM metal printers

Sciaky, which is a subsidiary of Phillips service industries, sold four of its metal additive manufacturing machines last month, which will be used to 3D print titanium structures for aerospace applications, as well as to produce large parts for ground-based military vehicles, and warships.

These machines use Sciaky’s Electron Beam Additive Manufacturing approach. This uses an electron beam that deposits metal (via wire feedstock), layer by layer, until the part reaches near-net shape and is ready for finish machining. It’s possible to create alloys by feeding two different wires into a single melt pool. In theory, metal wire should be cheaper than using powders as a raw material. This process can produce titanium, tantalum, and nickel-based alloys.

Sciaky claims that that its EBAM process has the fastest deposition rate of an additive metal machine, with gross deposition rates ranging from 3.18 to 9.07 kg of metal per hour, depending on the type of metal. It can be used to build parts up to 5.79 m x 1.22 m x 1.22 m or round parts up to 2.44m in diameter.

These printers use a real-time monitoring and control system called IRISS, or Interlayer Real-time Imaging and Sensing System. This is a closed-loop system that monitors and adjusts the metal deposition with a high degree of accuracy, which contributes to the consistent part geometry, mechanical properties, microstructure and metal chemistry of the parts produced.

Three of these new machines are the standard EBAM 110 model, while the fourth is a larger EBAM 150. This has a build area of 3708 x 1575 x 1575mm. All are due to be installed in the middle of this year.

Scott Phillips, president and CEO of Sciaky, commented: “Now, more than ever, manufacturers are looking for ways to reduce time and cost associated with producing large, high-value parts, and Sciaky EBAM systems have a proven track record of helping manufacturers achieve these business-critical goals.”

Sciaky has also hinted that there will be news of further sales later this month.
