Many common 3D printing problems, it turns out, can be chalked up to one thing: moisture. Your filament may look and feel perfectly dry, but most 3D printing filaments are hydrophilic, meaning that they love moisture and enthusiastically absorb it from the air. When moisture builds up too much inside the material, that's when you start hearing those disturbing snap-crackle-pop sounds during your print job and probably see some spectacular failures. The makers of PrintDry were sick of it, so they decided to do something about it, and after a great deal of research, the PrintDry Filament Dryer was born. The PrintDry. which is now on Kickstarter, is a small appliance in which spools of filament are placed and exposed to a consistent flow of hot, dry air that can run for up to 40 continuous hours. With temperature settings that range from 35°C to 70°C (95°F to 160°F), even the oldest, soggiest filament can be dried. Read more at 3DPrint.com: https://3dprint.com/153248/printdry-filament-dryer/
