The process of removing moisture from 3D printing material is essential for optimal print quality. Hygroscopic filaments, such as nylon and certain polycarbonates, readily absorb water from the atmosphere. This absorbed moisture can lead to various printing defects, compromising the structural integrity and aesthetic appearance of the final product. An example includes placing spools in a low-humidity environment with controlled temperature to extract moisture.
The importance of this procedure stems from the detrimental effects of moisture on filament properties. Excessive moisture can cause stringing, popping, and weakened layer adhesion. Consequently, the finished prints may exhibit reduced strength, dimensional inaccuracies, and a rough surface finish. Historically, manufacturers and hobbyists have employed various methods, ranging from sunlight exposure to specialized drying equipment, to combat these issues and ensure reliable results.
