About STL Format

STL (Stereolithography) is the standard file format for 3D printing. It represents 3D surface geometry as a mesh of triangles, without color or texture information. Supported by virtually all 3D printing software and services.

About STP Format

STEP 3D Model is a 3d model file format. Convert it to STL, OBJ, glTF, or other 3D formats for printing, rendering, or game development.
