High Performance Polymers

Ultrafuse® ASA


General Information

Ultrafuse ASA is a high-performance thermoplastic with similar mechanical properties as ABS. ASA offers additional benefits such as high outdoor weather resistance. The UV resistance, toughness, and rigidity make it an ideal material to 3D-print outdoor fixtures and appliances without losing its properties or color. When also taking into account the high heat resistance and high chemical resistance, this filament is a good choice for many  types of applications.
