I'm still VERY&HIGHLY skeptical of MC's business prowess. NOT, of the product. From the way I read it, with the exception of very few systems, Sigma has GIVEN AWAY nearly all of the Printrite3d systems for evaluation. Was there a clause(s) that there is a time frame for evaluation? Either returning the complete system or else purchasing a license when the evaluation time allotment expires (just look at GE-not a word from them in months and months - so much for lock step). Was there a clause that prevents use for production runs?Since it is an evaluation system. A lot of unanswered questions for me to even think of further purchases. I'm in hold pattern for now - leaning to sell if they don't get an actual paying sale soon.
