I took a SolidWorks class and when I walked in, I met my first professional 3D Printer. They told me it was $14000. Mine was $700 and the Prusa Mendel I am building is in the $600 range (a guess at this point). So my first question was “Is this PRO printer 20X better than mine?” Short answer: NO. Don’t get me wrong, it is better in more ways than one, but I would rate the quality at 2-3X better.
