What are some health and safety issues with bio printers?

Both of these materials emit numerous volatile organic compounds (VOCs), many of them toxic. In addition to VOCs, the printing process generates nano particles which pose a respiratory hazard. More novel applications involve the printing of biological scaffolds used to generate organs and other structures.
