Take a look a this paper. Here's an excerpt from the abstract.

"Direct writing (DW), also known as digital writing or digital printing, is a family of flexible multi-length scale processes for the deposition of functional materials to form simple linear or complex conformal structures on a substrate. This paper provides an overview of key DW technologies and their process characteristics under a unified classification system."

You'll have to pay for it, of course, but it seems to be worth it.
