Not sure, I quickly read an article at work the other day about HP had an impact on the 3d printing hitting DDD the hardest and its sister S**S not as hard but her earnings forecast dropped her today %10.8 today. I like the patents portfolio the two have. Hey, I wonder what patents ONVO are using to print their 3d organ tissues, they are working on printing whole organs next. Not looking for the answer but I will DD that one given more time. But that ones on my radar too.
DDD
