Dear Carl,
Apart from the SFF symposiums where i noticed there were an increasing no. of contributions in this area, your student could look at former research projects in this area, conducted in the UK too. I myself had worked on this topic for my research. Also one of the conferences held in April 2002 named "Metal powder deposition for rapid manufacturing" in Texas, USA which i attended then, had some interesting contributions in this area based on the LENS method of processing. A copy of that proceeding could be found with Loughborough's Rapid Manufacturing Research Group.

One thing he should definitely look at is biological materials. Almost every
organsim uses this trick (because it's so easy to do if you're building
bottom-up). Substances of particular note are bone, wood, insect cuticle, and
nacre (mother of pearl).
