Last time I was near one, I could clearly smell the unpleasant burning plastic.
- esskay 4y agoI know that smell, and rather annoyingly newer PLA's have somehow eliminated it. Which personally I dont see as a good thing. You used to know when someone was printing with PLA as it emitted a smell that was a mixture of a sweet popcorn and burning toast. These days they have little to no odour but I suspect its still putting out the exact same (if not worse) fumes.
- hot_gril 4y agoAh, that's unfortunate.
- Filligree 4y agoSome printers also come with full enclosures and HEPA filters, which do well at removing the smell -- and no doubt some of the larger fragments -- but do not actually remove the VOCs. A good, recirculating activated carbon filter can do that. But then you need to swap it once per week (whether or not you've been printing), and you need the right type of carbon.
