For more than 20 years the most common computer file format for 3D printing and exchanging product design between Computer Aided Design (CAD) and CAM software systems (and computational environments such as Mathematica) is called “STL.

A new file format that allows you to design projects significantly more complex and uses files 1,000 times smaller is called AMF for “Additive Manufacturing File.” This new format was developed and endorsed by American Society for Testing and Materials in 2011. It is backward compatible with STL file format.

This new format also adds native support for color, materials, and collections of shapes called “Constellations.”

The new format is able to easily resolve details as small as a micron. Its use of curved triangles dramatically broadens its capabilities and reduces the error on curved surfaces by 3 magnitudes.

Several design programs have added support for files including Digital Factory, Sculpteo, Netfabb, Materialise Magics, Polygonica, and Uformia.

To make your life easier your Design software should support the AMF file format.
