Alternative file format exports are also required to support depiction of complex organic geometry , whilst allowing multiple-material and mono/multicolour capabilities ; the development of STL 2.0 or Additive Manufacturing file Format ( AMF ) is promising , particularly for the composition of complex geometries and multiple-material .
