About
PA / Nylon
Nylon a.k.a Polyamide (in short PA) filament is an incredibly strong, durable, and versatile 3D printing material. Flexible when thin, but with very high inter-layer adhesion, nylon lends itself well to things like living hinges and other functional parts. Its low friction coefficient and high melting temperature make it an excellent choice for things like 3D printed gears.


3D Printing
PA / Nylon
Nylon is very hygroscopic which means it readily absorbs water from the air. Nylon can absorb more than 10% of its weight in water in less than 24 hours. Successful 3D printing with nylon requires dry filament. When you 3D print with nylon filament that isn’t dry, the water in the filament explodes causing air bubbles during printing that prevents good layer adhesion and greatly weakens the part. It also ruins the surface finish. Nylon filament storage becomes very important and requires special attention.
