AMF was introduced as an alternative to the STL file format to address many of the pitfalls of the current popular file format. STL files introduce errors such as leaks and inconsistences, and also does not support color, material choice, or orientation. Furthermore, STL files rely on triangle subdivision to account for curvature. As the STL file scales in size, retaining resolution means introducing significantly more triangles. For example, a 10cm sphere at 10 micrometer resolution requires 20,000 triangles. Scaling up the 10cm sphere at the same resolution would significantly increase the amount of triangles, resulting in a much larger file. AMF seeks to address these issues by redesigning the way a 3D object is digitally stored.
