Tim Gornet makes some interesting point about this technology. Namely the
time spent in setup vs. deposition. From what I've seen, LENS is a
near-net process that will require subsequent machining to produce a final
part. This is due to the fact that: 1) the metal must be deposited on a
substrate (usually a section that will be part of the final part), 2) the
surface finish is relatively coarse (scan deposition), and 3) some
distortion of large sections may result from residual stress.
Ti parts by this method are an attractive means to save on material cost.
One can make a part much closer to the final shape than a simple forging.
Stainless and aluminum are much cheaper and much easier to machine. The
benefits of LENS with these materials over conventional CNC machining are
not as stark.

Would anyone mind saying a few things about Laser Engineered Net Shaping?
What about the progress of AeroMet's application of Sandia research?
Where is this technology at, say with regard to commercial feasibility and
Why has development focused on the sintering of Ti? Would it be possible
use a process for fabricating in stainless or aluminum?
