to explore how emerging manufacturing technologies can be used to eectively process it. Additive manufacturing (AM) oers great design freedom. For the AM of metallic parts, several technologies are in use, including selective laser melt-ing (SLM), electron beam melting, laser engineered net shaping, and cold spray additive manufacturing.
Laser engineered net shaping (LENS), a laser beam deposition additive manufacturing method, has been utilized as a key technology in the direct manufacturing or repairing of metal parts. However, deposition defects such as pores, cavity, micro-cracks, residual stress, and uncertain microstructures always exist in the LENS fabricated parts ...
Laser engineered net shaping (LENS) has become a promising technology in direct manufacturing or repairing of high-performance metal parts. Investigations on LENS manufacturing of Inconel 718 (IN718) parts have been conducted for potential applications in the aircraft turbine component manufacturing or repairing. Fabrication defects, such as pores and heterogeneous microstructures, are ...
In 1995, Sandia National Laboratories developed a different approach to feed powder feedstock into DED with a laser heat source. This technology was first commercialised and trademarked as laser engineered net shaping (LENS), a sub-set of DED. The last major category of metal AM, Sheet Lamination, welds together sheets of feedstock to form 3D ...

Laser engineered net shaping advances additive manufacturing and repair free download shows the typical process layout. The deposition substrate or target is aligned to the desit point of the deposit. The powder feeder (s) feed the powder delivery nozzle assembly, which creates a powder stream that converges at the point of the deposit.
Additive manufacturing (AM) is causing a fundamental manufacturing paradigm shift that is changing how aircraft are now maintained and sustained. Sustaining an aging aerospace fleet is an enormous challenge. The U.S. Department of Defense maintains nearly $100 billion worth of spare parts and has to balance avoiding excess inventory [1] while ...
Laser Engineered Net Shape processing was evaluated as a means to repair scratched gas sample bottles and mis-machined test bases. Defects to be repaired were intentionally introduced. These defects simulated scratches and holes that had been either over bored or misaligned.
Laser Engineered Net Shaping {trademark} (LENS {reg_sign}) is a layer additive manufacturing process that creates fully dense metal components using a laser, metal powder, and a computer solid model. This process has previously been utilized in research settings to create metal components and new material alloys.
The process. A laser beam [1] created by a laser generator is focused through a lens [2] onto the workpiece. Metal powder [3], or metal wire, is introduced at the focus of the laser beam, where the metal powder and workpiece melt and thus building on the surface. An inert gas [4] is supplied to protect both the laser and the melt from ...
Laser powder forming, also known by the proprietary name ( laser engineered net shaping) is an additive manufacturing technology developed for fabricating metal parts directly from a computer-aided design (CAD) solid model by using a metal powder injected into a molten pool created by a focused, high-powered laser beam.
