The mtl file extension is related to Wavefront. Wavefront Technologies was a computer graphics company that developed and sold animation software used in Hollywood motion pictures and other industries. It was founded in 1984, in Santa Barbara, California, by Bill Kovacs, Larry Barels, Mark Sylvester.

They started the company to produce computer graphics for movies and television commercials, and to market their own software, as there were no off-the-shelf computer animation tools available at the time. In 1995, Wavefront Technologies was purchased by Silicon Graphics and merged with Alias Research to form Alias / Wavefront. It is now is owned by Autodesk.

Material library files contain one or more material definitions, each of which includes the color, texture, and reflection map of individual materials. These are applied to the surfaces and vertices of objects. Material files are stored in ASCII format and have the .mtl extension.

An mtl file differs from other Alias / Wavefront property files, such as light and atmosphere files, in that it can contain more than one material definition (other files contain the definition of only one item).
