Filament Mate Temperature display Greatly reducing the speed of water absorption of the filament Preventing dust from contaminating the filament Transparent observation window Filament Mate has a built-in highprecision digital thermohygrometer and Physical desiccant to keep the humidity inside the box below 15%, which can effectively prevent the 3D printing filaments from absorbing moisture during printing and storage. It is suitable for all 3D printing flaments, especially such as Nylon,PVA,PVB,PEEK,etc. which are diffcult to store fora long time due to high moisture abs
