What is ISO/ASTM 52915 about?

ISO/ASTM 52915 provides the specification for the Additive Manufacturing File Format (AMF), an interchange format to address the current and future needs of additive manufacturing technology.

ISO/ASTM 52915 specifies the requirements for the preparation, display and transmission for the AMF.

When prepared in a structured electronic format, strict adherence to an extensible markup language (XML) schema supports standards-compliant interoperability.

NOTE- A W3C XML schema definition (XSD) for the AMF is available from ISO and from ASTM. An implementation guide for such an XML schema is provided in Annex A.

Who is ISO/ASTM 52915 for?

ISO/ASTM 52915 on specification for additive manufacturing file format (AMF) Version 1.2 is useful for:

CAD programs developer
Additive manufacturing technology company
3D designer printing companies

Why should you use ISO/ASTM 52915?

ISO/ASTM 52915 helps the users with the detailed description of an interchange format to address the current and future needs of additive manufacturing technology. For the last three decades, the stereolithography (STL) file format has been the industry standard for transferring information between design programs and additive manufacturing equipment. An STL file defines only a surface mesh and has no provisions for representing colour, texture, material, substructure and other properties of the fabricated object.

As additive manufacturing technology is evolving quickly from producing primarily single-material, homogeneous objects to producing geometries in full colour with functionally defined gradations of materials and microstructures, there is a growing need for a standard interchange file format that can support these features.

The Additive Manufacturing File Format (AMF) has many benefits. ISO/ASTM 52915 describes an object in such a general way that any machine can build it to the best of its ability, and as such is technology independent. It is easy to implement and understand, scalable and has good performance. Crucially, it is both backwards compatible, allowing any existing STL file to be converted, and future compatible, allowing new features to be added as advances in technology warrant.
