Polymers for industrial 3D printing: Polyamide 12

Polyamide 12 in 3D printing

White polyamide 12 powder, also known as nylon, is the best-proven material on the market. Components made with it are robust, have long-term stability and are chemically resistant and extremely versatile. The polyamide 12-based materials from EOS are a high-performance alternative for plastics that have proven themselves in injection molding, such as ABS or PA6. The additively manufactured end products are just as strong, flexible and durable as injection molded products.

Areas of application:
This low-cost general-purpose material is suitable for a wide range of applications such as functional prototypes or qualified series production parts from industrial sectors.

Material Alumide® - Polyamide 12 filled with aluminum for industrial 3D printing

Alumide® - Polyamide 12 filled with aluminum

The metallic gray, aluminum-filled polyamide 12 powder is characterized by high stiffness, a metallic appearance and good post-machining capabilities. The surfaces of Alumide components can be very easily refined by grinding, polishing or coating. Machining is simplified by the chip-breaking effect of the aluminum filling. Alumide® is also characterized by its very high temperature resistance, which is reflected in its excellent dimensional stability at high temperatures. Parts made of Alumide® can therefore be functionally used at high temperatures.
