I've had my FT-5 for about a year now. Been mostly using PLA, but recently got into some PETG.
I'm looking to get into some Nylon (910) and possibly bridge from Taulman. I may even look at polycarbonate, but need to upgrade the thermistor in my hot end to be able to handle the 290+ hot end temps.
The printing fumes haven't bothered me or anyone in our house. I usually print maybe 2-3 things a week. The printer is in our laundry/storage area in our basement adjacent to our office/craft/hobby room. So, for the most part it's not in a typically busy part of the house.
However, I have been thinking about fumes more and more. Searching the internet gets mixed results, from those that are completely indifferent to the people who go all out. Ultimately, in my mind there is enough evidence that something should be done to help minimize the risk of exposure.
These are my current options, open for other suggestions:
These are all assuming that I will have some sort of immediate enclosure around the printer.
Vent the printer out the dryer vent
This would likely be simple and effective, but I live in Minnesota, and right now it's about 10 degrees F outside. Printers and materials are already susceptible to temperature changes, I don't like this option.
Put a room air purifier in by the printer and run it when printing
Purifiers run around $50-100
Mount this or build something similar(Compatible with 24V) into the top panel of enclosure
off the shelf small air purifier
I can purchase the filters for the small portable air purifier for 10 bucks, and a 24V, 120mm turbiune fan for another 10-12 bucks. 3D print a housing for it and put it in the top panel, vent it out the back. The unit specifies that it's suitable for a 10 M^2 room.
From what I've read, a hepa filter backed with active carbon filter will be helpful in eliminating the smell and possibly cutting down on the number of ultra fine particles in the air surrounding the printer.
What do you think? I'm leaning towards the 3rd option. Not necessarily because of cost, but because it will help with the fumes right away as they are being produced, and doesn't create more problems with the printer being drafty. I can also tie it right into the printer, and have it turn on with the printer.
Has anyone else considered air quality around the printer with exotic filaments, what are you doing to combat it?
