A .STL (Stereolithography) file format is a triangulation 3D model representation format used in most of the manufacturing systems and for 3D printing. The .STL file format represents only the surface geometry of various objects and can be saved either in Binary format or ASCII format. The .STL coarseness and faceting of the triangulation 3D model, and the .STL coarseness and faceting for 3D printing depends on the parameters that are provided to output the .STL file. Further, the .STL can be exported to the manufacturing systems such as CAD/CAM.
When you install one of the applications from the list of programs that you found here, you should be able to open or edit the file with the STL extension without any issue. However, if you still have problems with this, you may use the option of STL file conversion to a different format.
We hope we helped you solve the problem with the STL file. If you do not know where you can download the application from our list, click on the link (which is the name of the program) - you will find more information there on the location where to download the secure setup version of the required application.
There can be more reasons which determine that you are not able to open the STL file (apart from the lack of the proper application installed).
First - the STL file may be incorrectly associated with the application installed to support it. In this case, you need to change this association by yourself. To do this, right-click on the STL file that you want to edit, click "Open with" and then select the program from the list that you have installed. After this operation, the problems with opening the STL file should be solved.
Second - the file you want to open can simply be damaged. Then, the best solution is to find a new version of given file, or download it again from the same source as before (maybe for some reason in the previous session the download of the STL file has not been completed and it cannot be opened properly).
If you have additional information about the STL file, we will be grateful if you share it with our users. To do this, use the form here and send us your information on STL file.
