Open STL File

The STL file extension, which stands for Stereolithography or Standard Tessellation Language, is widely used in a range of fields such as 3D printing, Computer-Aided Design (CAD), and even video games. This wide application is largely due to the file format's ability to hold information about 3D models, including the coordinates of vertices and normal vectors. As such, STL files are a cornerstone in industries that require the creation, modification, and sharing of 3D object designs.

3D Printing with STL files

If you've ever explored the world of 3D printing, you've likely come across STL files. They are the most commonly used file type for this purpose because they give detailed representations of the surface geometry of 3D objects without color, texture, or other attributes. To open and use STL files in 3D printing, you will need software like Ultimaker Cura or Simplify3D.

STL Files in Computer-aided Design

STL files also play an important role in Computer-Aided Design (CAD). Virtually any CAD software can generate an STL file of a design. Common CAD programs like AutoCAD, SolidWorks, or Fusion360 can open STL files allowing for measurements, modifications, and sharing of designs.

STL Files in Video Games

STL file format is also useful for developing video games. Game designers may use STL files when creating 3D character models or environments. For example, Unity and Unreal Engine can both import STL files, although they may require conversion to a different format for optimal use.

STL File Important Information

It's necessary to remember that while STL files are formatted for the express purpose of providing information about 3D objects, they lack the ability to provide color, texture, or other aesthetic information. Furthermore, please note that while there exist both ASCII and binary versions of STL files, binary files are markedly smaller and quicker to load.

Typical STL application file locations:

  • %SystemRoot%\system32\rundll32.exe cryptext.dll
  • C:\Windows\system32\rundll32.exe cryptext.dll,CryptExtOpenCTL %1

Typical STL mime types:

  • CryptExtOpenCTL %1
  • application/vnd.ms-pki.stl

Frequently associated Windows objects:

  • STLFile
