Time would be against this issue. Every business tries to pay short term liabilities with long term assets fails. Rinos take up more space than 3D printers. And when was the last time one herd of a 3D printer the size of a large freezer charging at a person?
I can think of something just as good, have the 3D printed product have a superior result using the same testing on 'natural' stuff. At a cheaper price, for a better procduct? Folks have a mass tendency to always purchase the cheaper product that is better. After a short while, who needs to even go out into the bush to deal with harvesting issues.
