Lockheed Martin Space Systems will use a turnkey electron beam additive manufacturing (EBAM) system from Sciaky Inc. in the production of titanium propulsion tanks. (Sciaky, Inc., a subsidiary of Phillips Service Industries, Inc. (PSI) and provider of large-scale additive manufacturing systems.)

Sciaky’s EBAM process combines computer-aided design (CAD), electron beam manufacturing technology and layer-additive processing. Starting with a 3D model from a CAD program, the fully-articulated, moving electron beam gun deposits metal (via wire feedstock), layer by layer, until the part reaches near-net shape. From there, the near-net shape part requires minor post-production machining. The 110 in. x 110 in. x 110 in. (L x W x H) build envelope allows Lockheed Martin to produce large titanium parts with virtually no waste.

Lockheed Martin Space Systems designs, develops, tests, manufactures and operates a full spectrum of advanced-technology systems for national security, civil and commercial customers. Chief products include human space flight systems; a full range of remote sensing, navigation, meteorological and communications satellites and instruments; space observatories and interplanetary spacecraft; laser radar; fleet ballistic missiles; and missile defense systems.

Besides offering innovative additive manufacturing solutions for metal parts, Sciaky provides state-of-the-art electron beam and advanced arc welding systems, as well as job shop/contract welding services, for manufacturers in the aerospace, defense, automotive, and healthcare industries. Sciaky’s welding equipment meets rigid military specifications to manufacture items such as airframes, landing gear, jet engines, guided missiles and vehicle parts.
