3.1 STL Files and Standardization

For 3D Printing process, format that we regularly use is Standard Tessellation Language (STL) format. These files serve as a common format for representing 3D models and are essential for communication between CAD software and slicing software.

Beside STL format, Slicer Software is also compatible with OBJ, AMF, STEP and 3MF format. For a more detailed explanation, we recommend visiting ALL3DP website to study in depth for 3D Format.
