I do full stack myself, from electronics design, part design, software, and qa. I have an associates degree for drafting/3d design along side a specialty in plastics. My hunch was that thermoplastics was going to take off after the expiration of the patent in '09. Lo and behold... No, I would love a 3d printer that would only take seconds to make a part. However, with ABS, we're effectively limited to about a 200mm/s@.35mm is about the top end of printing. Obviously we can add in more hotends and other tricks, but the flow of ABS itself is the limiting factor. And about the supports, I've usually approached them more from a metal casting way. Making a sprue network isn't difficult; the only weirdness is to design the 'infill' in the STL, rather than let the slicer handle it. Because usually, I want a 5% rectilinear infill for the sprues and something better (say, 30% honeycomb) for the part. Ideally, I'm working on a way to delineate areas that I want different infill on slic3r. That would be pretty spiffy. Also, have you seen Antimony on the CAD front? http://www.mattkeeter.com/projects/antimony/3/ http://www.mattkeeter.com/projects/antimony/3/ Pretty neat idea, similar to the system in Blender.
