What is an STL File? (STereoLithography Format Explained)
The STL file format (short for STereoLithography) was developed by 3D Systems, a pioneer in the 3D printing industry, to simplify rapid prototyping and manufacturing processes. Today, STL files are one of the most common file types used in computer-aided design (CAD), digital fabrication, and additive manufacturing workflows. STL models exclusively represent 3D geometry as a triangular mesh, offering high compatibility and fast processing across various 3D printers and modeling software.
Key Features of the STL Format
- Lightweight and Simple: An STL file contains only the coordinates of vertices and normal vectors of triangles, making it extremely easy for 3D software and printers to interpret.
- No Textures or Materials: STL models do not store color, texture, transparency, or material information, resulting in pure geometric representations without extra attributes.
- Two Storage Methods: STL files are available in two distinct formats:
- Binary STL: The most popular choice due to its small file size, ideal for faster saving, sharing, and printing.
- ASCII STL: A human-readable text format that explicitly describes each triangle but produces significantly larger files.
- No Fixed Units: The STL format does not define units (millimeters, inches, etc.). Most programs assume millimeters by default. Our STL files converter can automatically handle unit adjustments during file conversion if needed.

X File - Microsoft DirectX 3D Model Format
The .X file format is a legacy 3D graphics format developed by Microsoft for DirectX applications. Introduced in 1995, it was widely used in Windows-based 3D games and multimedia software to store mesh geometry, materials, textures, and animation data. Although now outdated, the X format remains important for archiving and converting legacy DirectX assets.
Key Features of the X File Format
- Microsoft Origin: Created for use with DirectX on Windows 95 and beyond.
- 3D Mesh Support: Contains vertex positions, faces, normals, and other mesh details.
- Skeletal Animation: Supports bone-based rigging, keyframe animations, and skinning weights.
- Texture Mapping: Includes UV coordinates for accurate image-based texturing.
Convert X Files to Modern 3D Formats
Preserve your legacy DirectX 3D content with our reliable Autoconverter and Automesher Application. Effortlessly convert .X files to STL, OBJ, SKP, STEP, 3DM, and other standard formats used in 3D printing, CAD design, and visualization software. Whether you are updating old game assets or integrating classic models into modern workflows, our X file converter ensures full compatibility and data fidelity.
