Nylon (Polyamide) is a highly durable material that is resistant to abrasion, making it ideal for technical parts. It has excellent layer adhesion and, while it is mechanically strong in large volumes, it remains flexible in thinner layers. Its coefficient of friction is low, melting temperature is high. However, polyamide is hygroscopic, so it is necessary to keep it dry (airtight with desiccant). Improper storage can lead it to absorb water weighing up to 10% of filament weight. Polyamides emit a strong odor with potentially dangerous ultrafine particles (UFPs) so printing in a well-ventilated room or in an enclosure is a must. Recommended printing temperatures are 285°C for the nozzle and 110°C for the bed.
