My recent writing has been leading me down strange research paths, including metallurgy in general and Damascus steel in particular.

The technique for making Damascus steel was lost, but people keep trying to recreate it and getting close but not all the way there.

So I was interested to run across this attempt, which involved 3d-printing with lasers.
