STL is a triangle-mesh format and the standard for 3D printing. Slicers such as PrusaSlicer, Cura and Chitubox read it.
In more detail
STL stores only the surface triangles, with no units. Jewelers print a stone in resin to test a setting before they cast metal.
How we measure it
Our STL files are watertight, so they print and cast without repair. Our tools also read your own STL files.

- Mesh: A mesh describes a 3D surface as many small flat triangles joined at their edges. STL, OBJ, FBX and GLB files store a mesh.
- 3D model: A 3D model of a gemstone is a digital solid of its facets for CAD, rendering, printing or games. An exact model has flat facets, sharp edges and a closed, watertight surface at real size.
- Watertight: A watertight model is a closed surface with no holes, so it encloses a solid. In a closed mesh, exactly two triangles share every edge.
