PA12 vs PA11: Which Nylon Material is Right for Your Project?
Compare the properties, applications, and benefits of PA12 and PA11 materials for SLS 3D printing to make the best choice for your needs.
PA12 vs PA11: Which Nylon Material is Right for Your Project?
Choosing the right material is crucial for successful SLS 3D printing. PA12 and PA11 are the two most popular nylon materials for laser sintering, each offering unique advantages.
PA12: The Industry Standard
PA12, also known as Nylon 12, has been the workhorse of SLS 3D printing for decades with excellent stiffness, dimensional stability, and chemical resistance.
Key Properties
Tensile Strength of 48 MPa, excellent dimensional stability, heat deflection temperature of 110°C, and outstanding resistance to oils and solvents.
PA11: The Sustainable Alternative
PA11 is a bio-sourced polyamide derived from castor oil, offering superior flexibility and impact resistance with 75% higher elongation at break than PA12.
Key Properties
Tensile Strength of 50 MPa, elongation at break of 35%, bio-based from renewable castor oil, and excellent fatigue resistance.
Material Selection Guide
Choose PA12 for maximum stiffness, best surface finish, chemical resistance, and cost-effective solutions for most applications.
Choose PA11 for flexibility, impact resistance, living hinges, bio-based sustainable materials, and better low-temperature performance.
Conclusion
Both materials excel in different applications. PA12 is ideal for most functional prototypes, while PA11 shines in specialized applications requiring flexibility and durability.
