Anshuman, yes, the BPM approach was truly 3-D in nature and was the first
non-layer-based fabber concept. Today's laser deposition techniques (LENS,
Optomech, POM, etc.) are variations on that theme. Although they currently
work in flat layers, they are not limited to staying that way and I don't
think they will.
