STL

Stereolithography

The STL file format is a widely used standard for representing 3D models, primarily in 3D printing and computer-aided design (CAD). It is supported by most CAD software, 3D modeling tools, and slicing programs like Cura, PrusaSlicer, and Simplify3D. The format stores surface geometry as a collection of triangular facets, defined by vertices and normals, but lacks advanced features like color, texture, or metadata, making it simple yet limited for complex applications.

DXF

Autodesk Drawing Exchange File Format

DXF is a CAD data file format developed by Autodesk for enabling data interoperability between AutoCAD and other programs. It is widely supported by CAD applications like AutoCAD, LibreCAD, and DraftSight, as well as 3D modeling and CNC software. The format uses ASCII or binary encoding, organizes data into sections like HEADER, TABLES, and ENTITIES, and supports 2D/3D geometry, layers, blocks, and metadata for complex design sharing.
