The STL file format has its roots in the 1980's and is the native file format for 3D Systems stereolithography CAD software. The format defines a triangulated mesh with vertices and faces and is a popular format for sharing 3D printable model files.

There were several formats that attempted to extend the STL format namely SolidView and VisCAM whose formats included limited 15-bit color information for each mesh face which is often ignored by most modern 3D software. The STL format can be either Text or Binary, our tools will support both formats.

When converting 3D Model/Mesh files using our [ey] converter we will attempt to convert color materials into a suitable format for use in the converted file.

ExtensionAMF

The AMF or Additive Manufacturing File format is an open standard 3D file format primarily used within additive manufacturing processes such as 3D printing. The initial release version of the file was in 2011 and the format continues to be developed today.

As this is a 3D file format the contents which are Xml based describe one or many 3D objects broken down into solid volumes defined with vertices and triangles. The format has support for color and texture materials.

AMF Converter Capabilities

When converting your STL to AMF our tool will attempt to accurately convert any color/material information.

Information for converting from STL to AMF

Your STL file will be converted to a AMF file using our unified 3D model and mesh conversion tool. Our STL 3D tool performs accurate conversions of 3D elements such as vertices, faces, normals and relevant material information. As both STL and AMF support color material information our tool will also attempt to convert the color information too.
