What is an .AMF file?

.AMF is Additive Manufacturing File

An AMF file is an additive manufacturing file used by CAD programs to describe objects for 3D printing purposes. It contains one or more objects, which include the geometry, color, and material of the volumes that make up the object(s). AMF files also store the constellation (arrangement) of multiple objects and metadata that specifies the author, name, copyright, and special instructions for the object(s).

Since the 1980s the .STL format has been the industry standard for storing and transferring information between CAD programs and additive manufacturing tools. Now, with the rise of 3D printing, more capable formats are needed to store and transfer all the necessary 3D object information for 3D printing. This need has led to the increased popularity of the .3MF and AMF formats.

The AMF format is an open format developed by the American Society for Testing and Materials (ASTM) released in 2013. The format is designed to be a unifying solution for storing 3D object information much like the .PDF format is for storing documents. It is XML-based and was designed to be simple, scalable, and backwards and future compatible. The format uses triangle meshes for describing surfaces, whether they are curved or non-planar edges on 3D surfaces. Colors are specified using RGBA (red, green, blue, and alpha channels) values.

You can export 3D object information to the AMF format using programs such as Dassault Systemes SOLIDWORKS and Autodesk applications. 3D printers that support the format include Materialise and Shapeways. You can view AMF files with the free cross-platform Autodesk Meshmixer application.

How to solve problems with AMF files

  • Associate the AMF file extension with the correct application. On :
    Windows: Right click on any AMF file and then click "Open with" > "Choose another app". Now select another program and check the box "Always use this app to open *.AMF files". Mac: Right click (or Ctrl-click) the AMF file, then click "Open with" > "Other...". Then choose another program and check the "Always Open With" box. Linux: Right click on the file, and select "Open with" and choose another program. iPhone: Tap the file. If you do not see an app to open the file, then tap Share "Share" and choose an app. Alternatively, save the file. Then open the Files app Files app. There long-press on the file, then release your finger. You will see a black menu bar. Then tap "Share" and select an app. Android: Tap the Settings icon on your smartphone, then tap on the Apps section. There tap the Options icon in the top right-hand corner of the screen to change the default apps.
  • Update your software that should actually open .AMF is Additive Manufacturing File. Because only the current version supports the latest AMF file format. Search, therefore, e.g. on the ASTM manufacturer website after an available .AMF is Additive Manufacturing File update.
  • To make sure that your AMF file is not corrupted or virus-infected, get the file again and scan it with antivirus software.
