Study says that 3D printers can emit hazardous micro or nano particles which can embed themselves in your lungs permanently.
Ventilation is the key.

@aniket An even time-wise closer example would be asbestos.
@aniket I always wondered about that. Microplastics are everywhere anyways. In the far future we will be seen as we now see the ancient Romans who used lead in everything, even edibles.
