Then i found outnhow much blood banks were making selling donated blood to hospitals and other places that nneded blood or plasma. It was discusting, not to mention the huge salaries that were supported basted on these fees. I think one story was based on the Central Florida Blood Bank. I think NPR's Planet Money did a show on this also. Do not believe all those " our reserves are low, donate now". Sorry, it was Radio Lab -

This then brings up the important question, how do you "...Restrict the use of a a 3D printer to make guns.."? Is it at the hardware level, with some analysis engine used to determine if the shape matches some predetermined "firearm" pattern? Is it in the 3D CAD software that flags weapon like designs? or does it get so bad that the purchase of any 3D printer (CNC machine, mill, lathe, drill press, sander, dremel, will also eventually fall into this category) will require the purchaser to jump through hoops similar to steps needed to purchase class 3 firearms? Afterward, the operator will have to be licensed to operate the machine and personally verify the design being generated.
