Material
FDM Nylon
FDM nylon is a tough, wear-resistant engineering plastic known for high impact resistance, low friction, and the ability to flex repeatedly without cracking, all of which make it ideal for functional, moving parts.
Manufacturing processes
About
FDM nylon – most commonly PA12 for 3D printing – is valued for excellent impact resistance, low friction, and outstanding wear resistance, which makes it a strong choice for parts that experience repeated motion or friction.
It can flex and bend significantly before breaking, therefore suiting snap-fits, living hinges, and other parts that need some give under stress. It also resists many oils, fuels, and solvents, though strong acids can degrade it over time.
Like other nylons, it absorbs some moisture from the air, which can gradually affect dimensional stability and mechanical properties, though PA12 specifically absorbs much less moisture than other nylon types like PA6.
FDM nylon suits gears, bearings, bushings, hinges, and functional parts that need to withstand friction, motion, and repeated stress.
