I was recently at HP labs and got to see the mono color printers in action. The process is very consistent, and they told me that the parts are very uniform. Given my own observation of a bunch of finished parts and the active process, it produces very consistent results. The pieces were pretty damn durable. (I couldn't break them by hand). They used either Nylon or Glass Fiber reinforced Nylon.
