New Media Printmaking using the Makerbot

Printmaking is experiencing a Renaissance these days.
In January, 2013, I was introduced to some new work in the media involving CNC machinery to create relief blocks, and I thought – what about the 3d revolution? I am new to thingiverse, and my collaborator Dr. Jon Bath encouraged me to post my researches on this website.
Before I begin, I noticed a post has been made earlier which will serve as a much better introduction to experimentation in this new media, see Jasonwebb’s designs here:

I work in a format much larger than the Makerbot would allow, so I have integrated into my designs interlocking tabs (1/16” allowance) which allow for the creation of a puzzle-piece type assemblage. This technique could possibly be used to create larger blocks in a similar way. As my experiment progressed, I abandoned this technique and began to favor multiple press runs of the same block; inking and replacing the block for different colours, ori
