They come in small packets with goods such as trainers and food products because they are amazing at absorbing moisture. Also, ovens have quite wide margins of error on their temperature, especially at the lower ranges so I wouldn’t completely rely on your oven’s settings unless you have tested your oven temperature accuracy separately. If the Tg is less than 80 degrees Celsius, you can try to dry the filament at a lower temperature of around 30-40 degrees Celsius, but perhaps leave it in there for longer. The higher the glass transition temperature, the higher heat you’ll need to implement to adequately take the moisture out of your filament. Many commonly used 3D printer materials tend to absorb water from the air, and this causes a number of negative effects when printed. Nylon etc..

Read on for your guide to storing filaments correctly so that you don’t end up losing money on filaments that give you low-quality prints. When I first put the filament in the PolyBox the humidity was at 50%, after about 12 hours (I checked the next morning) it was down to 10% and has stayed there since. Filament clips are cheap and not using them would be equivalent to taking a really unnecessary risk. Resin 3D printing can get quite messy, and even complicated to beginners, so anything that helps simplify that process is welcome. Any parts printed with this “wet” filament will not look as polished or pristine as you want them to. Some oven settings don’t actually go as low as 60°C, so in this case you’ll need to either use a friend’s oven, or use a different method. isn’t entirely accurate. The even flow of air means that warm air constantly circulates around the spool. Set your bed’s temperature to around 150°F  (65°C) and lay your filament down for around 6 hours and it should do the trick. The first step in keeping your filament dry is to keep it dry during storage. But if I was being a bit pedantic “Filaments used for 3D printing purposes are polymers, meaning they can be broken down in a process known as hydrolysis”. PLA does pretty well at humidities even around 50%, but some filament won’t work well at all at that level. It’s more of a way for long term storage. Use double-zipped vacuum bags with a valve for sucking the air out with a standard vacuum cleaner. To dry PLA filament, most people simply put it in an oven for a couple of hours at a temperature of 120°F (50°C) and it comes out just fine. 1 object.
