Hello guys, I'm developing a powder bed metal 3D printer, here is my work:

I would like to get feedback and ideas about the following issues:
Eye protection
Respiratory protection

Those printers use very volatile powders and I would like to make a product that will not need the operator to be in any way exposed to the powder. The eye protection could be pretty easy but I'm still thinking of a cheaper way than a camera and a screen outside the box.
