Nylon 6/6: A Comprehensive Overview
Nylon 6/6 is a strong and resilient material. Find out its manufacturing advantages and how it’s used in various sectors.
Introduction
Nylon 6/6, also known as polyamide 6,6, is an engineered plastic in the nylon family. First created in the 1930s, nylons are prized for strength, longevity, and sustainability.
At our manufacturing company, helping customers select the right materials is important. One option we recommend is Nylon 6/6 due to its versatility and suitability for diverse applications.
What is Nylon 6/6?
Overview
Nylon 6/6 is a type of plastic made from two chemical building blocks, known as monomers: adipic acid and hexamethylenediamine. Each of these monomers contains 6 carbon atoms.
The "6/6" indicates the number of carbon atoms in the monomers. This specific composition gives Nylon 6/6 distinct properties that set it apart from other nylons, like Nylon 6 and Nylon 12.
Characteristics
Strength: Nylon 6/6 is generally stronger and stiffer than other nylon types.
Heat Resistance: It has higher heat resistance, making it suitable for demanding applications.
The "6/6" in the name refers to the number of carbon atoms in these two monomers. This specific chemical composition gives Nylon 6/6 its unique properties and characteristics, which make it different from other types of nylon, such as Nylon 6 and Nylon 12.
These characteristics make it a popular choice for many applications in industries like 3D printing, automotive, and electronics, where these properties are important.
What are Nylon 6, Nylon 66 and Nylon 12?
In addition to Nylon 6/6, there are a few other types of nylon that are important to understand, as they have some key differences compared to Nylon 6/6.
Nylon 6
Nylon 6 is another common type of nylon. It is made from a single monomer called caprolactam, which has 6 carbon atoms. This simpler chemical structure gives Nylon 6 some different properties compared to Nylon 6/6. Nylon 6 is generally considered to have lower strength and stiffness, as well as lower heat resistance, than Nylon 6/6.
Nylon 12
Nylon 12 is a versatile nylon material known for its excellent abrasion and chemical resistance, good impact strength and flexibility, as well as low moisture absorption. These properties make it well-suited for producing mechanical components, functional prototypes, and other parts that need to withstand demanding conditions. Nylon 12 is particularly popular for use in Selective Laser Sintering (SLS) 3D printing due to its ideal processability in that technology.
Nylon 66 (or Nylon 6,6)
Nylon 66, which is also sometimes called Nylon 6,6, is actually the same material as Nylon 6/6.
Nylon 6 vs. Nylon 12 vs. Nylon 6/6

Nylon 6/6 in 3D Printing
Nylon 6/6 is a popular material for 3D printing due to its excellent properties. Here are some common 3D printing technologies that use Nylon 6/6:
FDM Printing
In Fused Deposition Modeling (FDM) printing, Nylon 6/6 is made into a filament. The filament is fed through a heated nozzle, where it melts and is deposited layer by layer to create a 3D object. Its strength and heat resistance make it ideal for functional parts and prototypes.
SLS Printing
Selective Laser Sintering (SLS) printing uses a laser to fuse Nylon 6/6 powder particles together. This process allows for the creation of complex and durable parts. The chemical and thermal properties of Nylon 6/6 enhance its performance in SLS printing.
Nylon 6/6 Filament Production
Before using Nylon 6/6 in FDM 3D printing, it must be made into a filament. This involves melting the nylon and forcing it through a die to create a continuous filament. The filament is then cooled and wound onto spools for use in FDM printers.
High-quality and consistent Nylon 6/6 filament is crucial for achieving great 3D printing results. We prioritize sourcing and processing Nylon 6/6 to provide our customers with the best possible experience.
Advantages of Nylon 6/6

Challenges of Nylon 6/6
While Nylon 6/6 is excellent for 3D printing, there are some things to keep in mind:
1. Moisture Absorption
Nylon 6/6 absorbs moisture, which can weaken the material. To avoid this, the filament must be stored properly to prevent moisture buildup.
2. UV Sensitivity
Exposure to UV light, like sunlight, can damage Nylon 6/6, causing it to discolor or become brittle. Parts exposed to the sun may need extra protection.
3. Environmental Impact
Nylon 6/6 is recyclable but the process can be more complex than other plastics. For customers concerned about sustainability, recycled Nylon 6/6 or alternative materials might be better options.
Conclusion
Nylon 6/6 is a strong, flexible, and heat-resistant material, making it ideal for high-performance parts in 3D printing. It works well with both FDM and SLS 3D printing technologies.
