  • ❓ How can I convert SMD to STL?
    First you need to add file for conversion: drag and drop your SMD file or click the "Choose File" button. Then click the "Convert" button. When SMD to STL conversion is completed, you can download your STL file.
  • ⏱️ How long does it take to convert SMD to STL?
    Mesh conversion is pretty fast. You can change SMD to STL in a few seconds.
  • 🛡️ Is it safe to convert SMD to STL on AnyConv?
    Of course! We delete uploaded files immediately, and converted ones after 24 hours. No one has access to your files. File conversion (including SMD to STL) is absolutely safe.
  • 💻 Can I convert SMD to STL on Mac OS or Linux?
    Yes, you can use AnyConv on any operating system that has a web browser. Our SMD to STL converter works online and does not require software installation.

Information about SMD and STL file formats

Full name Valve Studiomdl Data format Stereolithography File Format
File extension .smd .stl
MIME type
Developed by Valve Corporation 3D Systems
Type of format
Description Source Engine (gaming engine that was used for developing such video games as Half-Life) 3D model file with the model saved using an ASCII text format. It can be compiled into the resulting MDL game model with Studiomdl command line tool and a QC script. STL is a file format native to the stereolithography CAD software created by 3D Systems. This file format is supported by many other software packages. It is widely used for rapid prototyping, 3D printing and computer-aided manufacturing. STL files describe only the surface geometry of a three-dimensional object without any representation of color, texture or other common CAD model attributes. The STL format specifies both ASCII and binary representations. Binary files are more common, since they are more compact.
Technical details An STL file describes a raw, unstructured triangulated surface by the unit normal and vertices (ordered by the right-hand rule) of the triangles using a three-dimensional Cartesian coordinate system. In the original specification, all STL coordinates were required to be positive numbers, but this restriction is no longer enforced and negative coordinates are commonly encountered in STL files today. STL files contain no scale information, and the units are arbitrary.
