Toxic? Where to put printer?


All my surfaces are covered with polythene sheets which can be replace when necessary.


OMG, are you my great aunt? Now I know why all the couches were covered in plastic, she was really secretly into SLA printing!



told you I think I red somewhere on forum


The box it came in can act as an enclosure. Just place the printer on the floor and the box over the top of the printer when in use. Seal the holes in the box with some tape.

This is my temporary solution while i have this printer at home during the pandemic.


It’s pretty nasty, and some resins are worse than others. I’ve found the elastic to be unbearable, while the clear isn’t that big of deal.

It’s fine to visit it, but you’ll want to create at least a little bit of exhaust ventilation from the room its in. If you have something like a laundry room with an exhaust fan, that would be ideal. Make up a solution based on your available spaces, but you don’t want to sleep with the fumes!


I keep my Form 2 in a small room with my AeraMax air purifier turned on.
So no dust, no smell, everything is fine.


The resin is toxic to some degree and it’s not advisable to be in long contact with it - nobody can predict what will happen if you’re exposed on the fumes for long period of time. Plus - the resin smells bad.

Personally I placed my Form3 into a cabinet (single section wardrobe from IKEA), drilled a hole on top and placed weak air extraction (get standard 15W/220V extraction fan and place 330nF/630V capacitor in series with the fan to reduce the speed). The air extraction is taking the air from wardrobe out from the room through air corrugated aluminium pipe like this one:

This solution guarantees no smells from the resin in the surrounding area.

Keeping the printer in dark, sealed cabinet also prolongs the life of the resin:

  1. Prevents from dust
  2. Prevents from UV light - some UV light penetrates the printer cover and can semi cure the resin (this is well visible if you keep the printer next door to windows or under direct sunlight).


There is so much bogus info. going around about the toxicity of photopolymer resin that it’s a wonder we haven’t all turned green and croaked.

My advice is to download the MSDS for each resin you print and read it.

From what I’ve learned doing so… it can cause redness and irritation of the skin and if your sensitive to it, it can actually cause a rash. If you drink it on a regular basis, it can cause birth defects in your offspring.

So my take away…

  1. ware gloves
  2. don’t drink it
  3. if the smell bothers me, I open a window.

That said, we cover the unit with a box turned upside down when not in use… primarily to shut out all light and preserve the resin in the build tank.


Long (chronic) exposure on some chemicals can cause serious health problems in long term. The resin might be harmless (just irritation or redness) if you have accidental contact with it, but may accumulate and slowly deteriorate your health.
