Nylon PA12 powder is a versatile and widely used material in the world of 3D printing. Its development marked a significant milestone in the evolution of 3D printing technologies, offering exceptional durability and versatility. PA12 is part of the nylon family, known for its high strength, durability, and resistance to wear and tear.

Material Composition

Nylon PA12 SLS powder is primarily composed of polyamide 12 (PA12), which is a synthetic polymer derived from dodecanedioic acid and 1,12-diaminododecane. These raw components are processed into a fine powder that serves as the feedstock for the SLS 3D printing process. This process involves selectively fusing the powder with a high-powered laser to create solid 3D objects layer by layer.
