Nylon or Polyamide (PA) is a strong and durable 3d printing filament. Known for being tough and strong, Nylon has great mechanical properties and high chemical and abrasion resistance. With high strength-to-weight ratio, high flexibility, low friction and corrosion resistance, PA is good for 3d printing tools, end-use parts and functional prototypes. SLS is most suitable printing technology for Nylon. Nylon 3d printing is more difficult with FDM and MJF (multi-jet fusion).
