Yes, great technology. We have one of the FDM (fused deposition modeling)
machines.
But one wonders, why did they go to all the trouble of laser scanning the part
and creating a plastic rendition when they could have simply used the old part
as a pattern to sand cast the new part?
If they really wanted to show off, they would have fabricated a new part from
the CAD data using an SLS process (selective laser sintering - Wiki it).
Think of a similar process to FDM, but uses powdered metal that is fused
together in layers using a laser. Strong enough for gears or tooling, and
certainly much stronger than a cast iron D valve.
