Nylon 6,6 is a polyamide polymer that is has been commercially produced since the 1930s. Nylon boasts one of the most versatile lists of properties of any 3D printing filament and can be used to produce some very functional 3D printed products. There are many different types of nylon. Nylon 6,6 is the most common type of nylon for use in the plastics and textile industry. the '6,6' refers to the fact that Nylon 6,6 is made from two monomers, each containing 6 carbon atoms: hexamethylenediamine and adipic acid. Another common type of Nylon is Nylon 6.

Nylon 6,6 is very strong and has an excellent durability to flexibility ratio. As well as being very flexible it also has great layer to layer adhesion, this makes it ideal for products that include living hinges (thin layers of flexible material that link two parts of the same material) and gears.

Nylon 6,6 absorbs water very well meaning that it can be easily coloured however it also needs to be stored very carefully. You can read our blog article on how to store you filaments for more information about this.

Nylon 6,6 has a printing temperature between 240°C and 260°C and will usually require a heated bed of around 75°C to ensure good bed adhesion. Nylon 6,6 prints with low warp although will warp if cooled too fast. Nylon has a great finish with very few rough edges requiring little post-processing.

With excellent, versatile properties and relatively easy printing Nylon 6,6 is a great choice if you need a durable and flexible 3D printing filament. Here at you can select the right Nylon 6,6 filament using our constantly updated list of suppliers and our comprehensive search tool!
