Note:
NASA Marshall Space Flight Center (MSFC) works to develop additive manufacturing (AM) for propulsion systems to produce complex and optimized components from an array of materials with numerous advantages over traditional manufacturing. Among AM technologies, Directed Powder Energy Deposition (LP-DED) technology is an AM process in which metal powder is injected into the focused beam of a high-power laser under tightly controlled atmospheric conditions. The focused laser beam melts the surface of the target material and generates a small molten pool of base material. Powder is delivered into this same spot and is absorbed into the melt pool, thus generating a deposit. The resulting deposits may be used to Freeform or Repair metal parts for a variety of applications. Many refractory alloys are reactive and highly susceptible to oxygen pick up in processing, leading to embrittlement or knock down in material properties. The tightly controlled environment of the LP-DED has shown the ability to reuse any of the powder not captured in a prior build, further gaining cost benefits from an already costly material. LP-DED technology has shown repeatable quality in the deposit from multiple use refractory powder and plays a key role in advancing the large-scale parts that can also consider use of refractory alloys.
