3D Printer Air Filter

thingiverse

This is my attempt to design an air filter for my 3D printer housed inside the lack enclosure. I have yet to receive the parts yet so this is still work in progress As we know, printing certain plastics emits bad smells & VOCs. It is important to print in either a well ventilated area or have it enclosed. HEPA filters cannot filter out VOCs and bad smells and thus you would require some sort of activated carbon filter The idea is to have the filtered air circulate within the enclosure itself for 2 reasons - Extracting air will cause cold air to be sucked in, thus dropping the temperature and causing certain plastics to warp - HEPA filters with activated carbon layers have effectiveness that are questionable. I'd rather have the air circulating within the enclosed space I used the xiaomi car air purifier filter as it is pretty cheap and compact and comes with a activated carbon filter version. I added an extra container that can be filled with activated carbon which will enhance VOC removal What you need to buy - 4x PC Fan Flat Head Screws - 2x 7530 blower/centrifugal fan - Power Supply for your fans - Xiaomi Car Air Filter https://www.aliexpress.com/item/4000238653383.html
