All You Need to Know About Nylon for 3D Printing

3D printing nylon (polyamide) is a strong, stretchy artificial material made from synthetic polymers. Often fashioned into bristles, fabric, or sheets, and used especially in textiles and plastics, it is one of the most widely used polymers in the additive manufacturing sector, with popularity growing. The global market valuation for nylon 3D printing filament is projected to reach $7.82 billion by the end of 2034, with a Compound Annual Growth Rate (CAGR) of 18.8%, according to DiReports. This thermoplastic is available in powder or filament form for technologies such as SLS, Multi Jet Fusion or FDM. These plastics are classified according to their chemical composition, according to the number of carbon atoms they contain.

The most well-known on the 3D printing market are undoubtedly PA12 and PA11, as well as PA6 for FDM. What are the characteristics of nylon when used for 3D printing? What are the applications? And who are the manufacturers? Find out more in our complete guide below!

How is Nylon Produced, and What Are Its Characteristics?

Nylon first appeared in 1935 in the form of nylon 6.6. It was developed by Wallace Carothers who then worked for the chemist DuPont. This first material was patented in 1937, commercialized in 1938 and remains the most widely used today. Nylon is mainly found in the textile industry thanks to its flexibility and resistance. It was used in 1940 for the first time in the production of women’s stockings. Even in 3D printing, one of the most interesting characteristics of this material is its flexibility. Nylon 6, on the other hand, was first produced by Paul Schlack in the laboratories of IG Farben and patented in 1941. All other forms of nylon came later.
