Powders
◦ Alumide is a blend of Polyamide (SLS) with Aluminum powder. While
the Polyamide provides properties of a rigid plastic material, the
Aluminum gives off a matte and metallic-looking surface that can also
resist high temperatures and is slightly porous. Alumide is printed
with Laser Sintering technology. It works by spreading a very thin layer
of powder on the surface of the machine bed, and a laser
successively melts thin lines in the powder that bond together to form
the layers of the model.
◦ Polyamide (Nylon) with its strength and flexibility, polyamide allows for
high levels of detail on a 3D-printed product. The material is especially
suited for joining pieces and interlocking parts in a 3D-printed model.
Polyamide is used to print everything from fasteners and handles to toy
cars and figures.
