Polyamide 12 for 3D Printing

White polyamide 12 powder, also known as nylon, is the most tested material for additive manufacturing on the market. Parts made from nylon are robust, stable for long periods of time, chemically resistant and extremely versatile. EOS materials based on polyamide 12 are a high-performance alternative to plastics like ABS or PA6 that have proven their value in injection molding. The additively manufactured end products are just as strong, flexible and durable as molded parts.

Fields of application:
This cost-efficient general-purpose material is suitable for a variety of applications, including functional prototypes and qualified series production parts from the industry.

Alumide® – Polyamide 12 Filled With Aluminum

This metallic gray, aluminum-filled polyamide 12 powder is characterized by high rigidity, a metallic appearance and a range of useful post-processing options. The surfaces of Alumide parts can very easily be finished by grinding, polishing or coating. The chip-breaking effect of the aluminum filling simplifies machining. Another impressive property of Alumide® is its very high temperature resistance, which results in excellent dimensional stability at high temperatures. Parts made from Alumide® can therefore be used in functional applications at high temperatures.

Typical mechanical properties

Tensile modulus 3800 MPa
Tensile strength 48 MPa 
Elongation at break 4% Z

 

Thermal properties

Melting temperature (20°C/min) 176°C
