Hey guy, how are you exhausting your printer when printing ABS or ASA. I have my duct from my exhaust fans at the back of the printer to my window which is about 4 feet away. Also I have the exhaust fan at 30% chamber, temp stays about 38 through out the 5 hour print. Oh I also have a 24v 120mm fan between the printer and the window which is running about 40%.
Important:
I’ve got many health issues when printing ABS using the wrong enclosure, and ended up having an operation to fix it.
I’ve used a DIY enclosure made of wood and tiles. I’ve added the first layer of wood and enclosed all of its sides. Then added marble tiles to the floor, sides and top side.
The exhaust fan was placed onto the top with a proper cutout that was sealed with heat-resistant silicon. This exhaust was then connected with a custom-made adapter (made it myself) and then to the beautiful world.
The door was sealed to prevent air from escaping to the room. I truly suggest that you place it somewhere away from you where you don’t normally sit.
Additionally, you could, if you have the money for it, build a proper room divider that makes a small space only for printers and put a sliding door for it. This way you isolate it.
Thank for the response, I thought exhaust it to a window was good enough. Outside the house I can feel the warm airflow out so I thought the fumes were extracting out. It’s cold her in NYC so I can’t print in my garage.
I’d really advise against using the printer in the same room. I had a full one year exposure to ABS and it messed up my whole body.
The cheapest options are really installing tiles onto the wood panels so that it doesn’t get humid and/or doesn’t get inflamed if something goes wrong.
The full sealing with a proper sealer is really advised. Something similar to windows sealing, with an open/close mechanism. Otherwise, you would still have low risk of getting exposed to it via the small gaps in between the panel frame and the enclosure body.
For your specific situation, consider the following:
- Install plug-n-play adapter with right & left exhausts (1 input / 2 outputs).
- Each side should be closeable, so that when the wind changes direction, you just open the other one.
- Make the exhaust far away from your actual intake airflow, so that you don’t throw the dirty air out and scoop it again (warm goes high, but if the temps are equal, and the wind is strong?)
- Seal the panels of the enclosure with proper window sealer and make it sturdy enough to hold the air and be air-tight.
- Connect the hose between the enclosure and outside adapter.
- When the 3d printer is not in use, the hose needs to be disconnected and the adapter hole should be closed so that the particles don’t go out.
- It’s advised to install proper carbon filters.
- Buying air purifier is also recommended, put it near it so it purifies the air.
