All About STL Files

STL stands for 'Standard Tessellation Language' and is the most commonly used format for the three-dimensional model file format.

STL files are generated by Computer-Aided Design (CAD) software and are widely used in 3D printing and other manufacturing techniques. This format has a series of triangular surfaces linked to create or produce the three-dimensional model. If the number of triangulations is higher, the model will have a higher resolution with fine features.

With 3D Usher's free online STL viewer, you can now view any STL files or open STL files without any software downloads, installation, and registered accounts.

To access and open your STL files, follow these steps -

Step 1: Open 3D Usher's STL viewer online;
Step 2: Upload your .stl format file from your desktop or mobile device;
Step 3: 3D Usher's STL viewer will load the model and display a 3D view of the STL file uploaded;
Step 4: Use mouse or fingertips on touchscreen devices to rotate the model in STL file viewer and access the 360-degree view of the STL files.

3D Designers can prepare STL files by developing the three-dimensional model in Computer-Aided Design (CAD) software. Few commonly used software are Tinkercad, Sketchup, Solidworks, Autodesk Inventor, CATIA, and Blender.

Once the model is prepared, the software provides an option to export the file in .stl format. The dimensions and scaling of the models have to be kept in mind while manufacturing these parts.
