Polyamide 12 (PA 12), also known as Nylon 12, is a high-performance thermoplastic polymer widely used in Selective Laser Sintering (SLS) 3D printing for producing functional prototypes, industrial parts, and end-use components. Known for its exceptional mechanical strength, thermal stability, and chemical resistance, PA 12 is the preferred choice for automotive, aerospace, medical, engineering, and consumer product manufacturing.

This material is ideal for high-precision 3D printed parts requiring durability, dimensional accuracy, and long-term performance under mechanical stress, wear, and harsh environments. Its low moisture absorption and smooth surface finish make it especially suitable for tight-tolerance assemblies, snap-fit components, and aesthetic prototypes.

 Key Properties and Characteristics of PA 12

• High tensile and flexural strength – Ideal for durable, load-bearing, and impact-resistant components

• Excellent chemical resistance – Resists oils, fuels, greases, solvents, and cleaning agents

• Heat resistance – Performs reliably in high-temperature environments, up to 170°C

• Low water absorption – Maintains stability and strength even in humid or wet conditions

• Superior wear and abrasion resistance – Suitable for gears, hinges, and moving parts

• Smooth surface finish – Easily post-processed for polished, painted, or coated finishes

• High dimensional accuracy – Enables complex geometries with tight tolerances and fine details

• Lightweight yet tough – Perfect for replacing traditional plastic or metal parts in demanding use-cases
