Is Your 3D Printing Filament Ruining Your Prints? The Ultimate Guide to Drying and Storage

This comprehensive guide tackles the often-overlooked issue of filament moisture in 3D printing. It details how hygroscopic filaments absorb moisture, leading to problems like stringing and poor adhesion. The guide covers different filament types and their hygroscopicity, symptoms of wet filament, and various drying methods, from dedicated dryers to oven drying (with strong cautions!). It also provides detailed storage solutions, emphasizing airtight containers with desiccants and vacuum-sealed bags. Proper desiccant care is also addressed, highlighting the need to periodically dry the desiccant itself.
