FBX files are an open 3D file format developed by Autodesk for use with their Maya and 3Ds Max applications. An FBX file may contain any number of 3D objects, their associated geometry, materials, textures, animations, and more, all within a single convenient package.

The content of an FBX file is a mix of binary and ASCII text, producing a format that is both human-readable and compact. Due to their compact size, ease of use, and widespread support, FBX files are a popular choice for creating 3D animations and are also a staple in the videogame development scene.

The development of the FBX format continues to this day, with new features being included in each release. Along with being used within Autodesk's own editing solutions, FBX files can also be opened and edited in other popular 3D modelling applications, such as Blender.

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

ExtensionSTL

The STL, or Standard Triangle Language, file format has been around since the '80s and is supported by most modern 3D modelling applications. In particular, the STL format has become something of a standard format within the area of 3D printing, despite the rise of more modern formats such as 3MF.

STL files come in two flavours: binary or text format. The text format is human-readable, making it easy to perform manual edits, but can lead to very large file sizes. As you can imagine, the binary format is much more compact and represents the majority of the STL files you are likely to encounter.

The format itself is very simple; the 3D model is represented by a sequential list of triangles, with each triangle defined with 3 points consisting of their X, Y, and Z positions, along with an additional vector that contains the face normal (the direction the face is pointing). There is an additional attribute block for each triangle; however, this is largely unused and thus unsupported.

STL Converter Capabilities

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

Information for converting from FBX to STL

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