Thanks Mr.E
Looks like Z Corp is in the 3 D printer business as well, but they are not public. Do patents expire after awhile? The 3D technology is not new at all. Just wondering what market share DDD curently holds. I know were not the only game in town. I understand the technology has been around for 30 years, just very expensive and probably slow.
Thanks
