PA12

PA12 Nylon - Engineered for Demanding Applications

When printed parts need to withstand repeated mechanical loads, friction or impacts, PA12 offers a combination of toughness, flexibility and durability that makes it particularly useful for engineering applications.

Unlike more rigid and brittle materials, PA12 can absorb mechanical stress through limited deformation without easily cracking or breaking.

Compared to PA6, PA12 generally absorbs less moisture, resulting in better dimensional stability and more consistent mechanical properties under changing humidity conditions. It also offers good chemical resistance to many oils, lubricants and fuels.

Common Applications for PA12 Filament

PA12 is frequently used in applications where long-term mechanical performance matters:

• Gears and moving components - parts exposed to friction and repeated movement.
• Brackets and connectors - durable components for mechanical assemblies.
• Robotics - moving parts, mounts and mechanical elements.
• Manufacturing tools and fixtures - jigs, production aids and functional prototypes.
• Protective enclosures - impact-resistant housings for electronics and technical equipment.

Printing PA12 Successfully

Nylon filament requires relatively high nozzle temperatures, a heated print bed and preferably an enclosed printing environment.

Although PA12 absorbs less moisture than many other polyamides, proper filament drying and storage remain important. Moisture can cause inconsistent extrusion, surface defects and reduced mechanical performance.

For reliable results, PA12 should be dried according to the manufacturer's recommendations and kept in a sealed, dry environment before and during printing.

PA12 is particularly suitable for experienced users producing durable functional parts rather than decorative models. Browse our PA12 nylon filaments and order online with delivery across Europe.
