The Grey Pro resin stinks. I think probably too many people are breathing the fumes and not using gloves when they touch the resin. I want to be as safe as possible so I use the machine next to a fume hood.
The problem I found having the machine actually inside the hood area was that the machine got really dusty. It was sucking all the dust in the entire room through that hood and the dust was sticking to the machine. I used a plastic spray cleaner that helped with the static on the Form 2 cover, but really that should be made of glass or an anti-static PC. So I moved the machine next to the opening instead of under. I still keep the resins and trays and Form Wash under the hood. Seems to work well. You just want a slight movement of air really so the room isn’t full of stagnant air.
