Very good points, Terry. I just read it very quickly I guess and focused on the patent expiration part. Still, many of the patents have already expired or will very soon. Say hello to the Chinese! Pretty soon Walmart will be selling these (and the consumables too). G. Sachs ________________________________ From: Terry Wohlers <> To: G.

That’s certainly not the case, nor does Formlabs sell a desktop laser-sintering machine. Charles Hull founded 3D Systems, not Stratasys. Scott and Lisa Crump were the founders of Stratasys. The final laser sintering patent (5,639,070) at the University of Texas at Austin expires in June 2014.   Terry   ******** Terry Wohlers Wohlers Associates, Inc. 970-225-0086     ________________________________ [] On Behalf Of G.
