Abstract Scope |
Nylon is a commonly used thermoplastic material featured for its high resistance to heat, chemical, and impact. Nylon filaments that facilitate complex part manufacturing through the extrusion-based 3D printing process are widely used by industry and can be easily acquired from various vendors or suppliers. However, as a hygroscopic material, nylon directly absorbs moisture from the surrounding air at a fast rate. This study concentrates on evaluating the moisture absorption of nylon filament in a humid environment. Experiments are conducted to correlate the moisture content of nylon filament with its dwelling time in a humidity chamber. Test artifacts are printed to demonstrate the influence of moisture on nylon part quality. Mechanical testing is also carried out for analyzing the material property degradation due to increased moisture content. Suggestions on nylon filament usage and storage are discussed. |
