PEKK (Polyetherketoneketone) is a high-performance thermoplastic used in 3D printing for its exceptional mechanical strength, chemical resistance, and high-temperature stability. It belongs to the PAEK family and offers superior wear resistance, low moisture absorption, and excellent flame retardancy. PEKK is ideal for aerospace, automotive, and medical applications where durability and heat resistance are critical. Its slower crystallization rate compared to PEEK allows for better printability and layer adhesion, making it a preferred choice for demanding engineering applications.
