Nylon is a resilient, durable, and strong plastic material with great chemical resistance.
Functional prototypes and small industrial parts are some of the ideal applications for 3D printing in nylon.

About Nylon

Nylon is a polymer from the synthetic Polyamides family, known for its high durability, strength and flexibility. This 3D printing material is commonly found in the variants PA 12 and PA 11, although other variants (PA 6 or PA 2200) are also available for 3D printing. In addition, nylon is often reinforced with fibers and particles from other materials to improve thermal and mechanical properties such as stiffness or abrasion resistance.

Due to offering outstanding mechanical properties, and good chemical, impact and heat resistance, 3D printing in nylon is ideal for functional parts and prototypes. Another advantage of this material is its relatively low cost.

Parts that are 3D printed in Nylon can be easily post-processed in any color. That is because Nylon exhibits hygroscopic properties which make it possible to change its physical characteristics by being exposed to moisture. However, being susceptible to absorb atmospheric moisture can also affect its performance. Nonetheless, this all-round material is a perfect choice for a wide number of applications such as connectors and hinges, medical prosthetics and small-series production of functional parts.
