Resin Odor

Just finished building my SL-1.  It went together very easily, nice jog Prusa!

My question is the odor associated with printing.  Does the SL-1's filters diminish it enough that I can use the printer in my home office?  I had a Peopoly Moai and had to use it in my basement because of the resin odor. 

 

Thanks

RE: Resin Odor

The filter does help diminish the smell while printing but not where it will be unnoticeable.   I find that the greatest source of odor is spread once the lid is open and you are handling the finished model for post-processing.  Even if you were to quickly move the part elsewhere to post-process, the odor will still permeate the area.

I would not recommend that you ever use a resin printer inside any home area.  Even though I have mine in my garage workshop (which has ventilation to the outside) the smell still lingers and travels into the room connecting to the garage.

The biggest source of odor when I first got it was the fresh Acrylic from the CW1. An air purifier with HEPA grade filters + carbon pre-filter should also be able to get rid of odors.

This!

I bought a desktop air purifier off amazon.  It's about the same size as a CW1 and I have it running simultaneously with any print I'm doing.  It decreases the odor a considerable amount.

RE: Resin Odor

I have made this box out of 3d pritned parts and plexiglass since I am using it in my home office and it almost solved the issue. It has a duct on the left side that goes directly to the intake on the left side of the printer. On the back there is a fan and a duct going to the window where I also have attached a fan to take care of the fumes appearing when handling the resin before and after the print. This reduces about 90% of the smell, but still smell a little bit and I cannot stay in the room for a prolonged amount of time. My guess this is because the solution in the window frame is not completly tight, but this is something I am working on. I am also looking into fitting a carbon filter or two on the duct going from the box to the window and maybe on the intake as well in case some air gets out that way. 

A consequence of having the box is also that it reduces the smell when poring the resin into the tank is reduced because of the fan in the back. 

I also think using a resin with less odor would be a good solution, but I do not have any spesific suggestions at the moment, but will try out a couple of alternatives in the weeks to come.

The setup is unremarkable, the air purifier is just sitting off to the side on the same table.  When I'm next to the printer I can smell the resin but a few meters away (where my desk is) I can't smell it.  The table is next to a window as well so I can always open that if necessary.
