3D Printer Filament Storage
The thermoplastic filaments used for 3D printing are more or less hygroscopic, meaning they absorb moisture from the air. High levels of moisture in the filament can ruin a print by affecting extrusion quality, cooling behavior, and layer adhesion. Furthermore, UV light can cause discoloration and brittleness. In short, we want to store filaments dark… Continue reading 3D Printer Filament Storage
