Nylon stands out as one of the most robust materials in FDM 3D printing. It may be familiar to many due to its widespread use in the clothing industry, where it is prized for its high tensile strength. However, it is also highly favored in industrial part manufacturing under the synonym PA (Polyamide).

Indestructible

Nylon components are nearly indestructible when it comes to mechanical toughness and exceptional layer adhesion. Instead of breaking, Nylon tends to deform when subjected to excessive force. Nevertheless, it maintains remarkable dimensional stability. Thanks to these qualities, Nylon is an excellent choice for load-bearing and mechanically demanding parts. Additionally, it boasts outstanding abrasion resistance, making it suitable for applications such as bearings and guiding components. Its high toughness also renders it suitable for parts that must withstand heavy impacts, such as end stops and protective coverings.

Stringing Phenomenon

After printing, Nylon components undergo annealing to enhance their mechanical properties. However, in thin-walled structures, this process can lead to warping. Thin sections of Nylon are also flexible, making it suitable for flexible hinges or film hinges. Since Nylon is heated significantly during the printing process, it can sometimes leave behind stringing artifacts on the printed object. These artifacts may not always be fully removable, potentially giving the print a somewhat "unclean" or even "fuzzy" appearance.

Printing Small to Medium-Sized Nylon Components

For very large parts, Nylon might not be the best choice due to its substantial shrinkage tendencies, which can lead to warping and detachment from the print bed. Nylon is most suitable for end-use components that require durability, along with a degree of flexibility and toughness.

Nylon is a versatile material widely employed in various industries, including aerospace, automotive, and manufacturing, for producing durable, resilient, and mechanically robust components. Its unique combination of strength and flexibility makes it a preferred choice for applications that demand the utmost performance.
