sciaky, inc., a subsidiary of phillips service industries, inc. psi and leading provider of metal additive manufacturing am solutions, has developed a new electron beam additive manufacturing ebam systems. the expanded lineup of ebam 3d printing systems includes new options for medium, large, and extralarge part applications, making ebam the most widely scalable metal 3d printing solution on the market in terms of work envelope for parts ranging from 203 mm 8 inches to 5.79 meters 19 feet in length.these systems all combine computeraided design cad, electron beam directed energy deposition, and layeradditive processing. starting with a 3d model from a cad program, sciaky&39s electron beam eb gun deposits metal via wire feedstock in successive layers until the part reaches nearnet shape. each system&rsquos vacuum chamber ensures the highest part integrity, while the eb gun maximizes material deposition rates by a range of 7 to 20 lbs. of metal per hour, which is the fastest and most efficient metal deposition process on the market. in addition, many ebam systems offer dual wirefeed arrangements to increase deposition efficiency, as well as to simplify the process of switching to different deposition materials. minor finish machining is required after the part reaches nearnet shape.sciaky&rsquos patented closedloop control clc system automates the ebam process. the clc system monitors the metal deposition process in real time and makes adjustments to the process parameters that compensate for changes that occur over time. ebam is the fastest deposition process in the metal 3d printing market, with gross deposition rates ranging from 3.18 to 9.07 kg 7 to 20 lbs. of metal per hour. with help of a dual wirefeed option, one can combine two different metal alloys into a single melt pool to create &ldquocustom alloy&rdquo parts or ingots. in addition to that the mixture ratio of the two materials can be changed to create &ldquograded&rdquo parts or structures. sciaky&rsquos ebam technology utilizes wire feedstock, which is available in materials such as titanium, tantalum, niobium, tungsten, molybdenum, inconel, aluminum, stainless steels, nickel alloys, and more.
