File format information for STL and STL

ExtensionSTL

Type3D Model
Mime Typeapplication/vnd.ms-pki.stl
FormatText
Opens WithBlender, MeshLab, CAD Assistant, DAZ Studio

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

Information for converting from STL to STL

Your STL file will be converted to a STL 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 STL support color material information our tool will also attempt to convert the color information too.
