Hi Adrian:

Something very close has been done. Neil Hopkinson and Poonjolai
Erasenthiran at Loughborough Univ have used carbon-blacked nylon for an object material,
and white nylon powder for support in a technique they call High Speed

They envision selectively jetting the black stuff, or jetting an energy
aborber on the surface of the stack as you describe - among other implementations.
Already has a UK patent and I'm guesing a search would turn up additional
prior art.

See this page for the abstract of their SFF '04 paper:
