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.

IV File - Open Inventor 3D Scene Format
The IV file format, also known as the Open Inventor format, is a text-based 3D graphics standard originally developed by Silicon Graphics (SGI). Designed for complete 3D scene representation, IV files use hierarchical scene graphs to define geometry, lighting, materials, and textures. The format played a key role in early 3D development and is tightly integrated with the Open Inventor API - an object-oriented C++ toolkit used in scientific visualization, CAD, and simulation.
Key Features of IV Files
- Readable File Structure: Human-friendly ASCII format that organizes 3D content using nested nodes for easier editing and scripting.
- Scene Graph Hierarchy: Defines parent-child relationships between 3D objects using a directed acyclic graph (DAG) structure.
- Rich Visual Metadata: Includes lighting, shading, camera settings, and full material definitions (specular, ambient, diffuse, transparency).
- Texture Support: Handles both procedural and raster-based textures using UV mapping coordinates.
- Legacy Compatibility: Ideal for scientific and engineering applications that still rely on Open Inventor-based platforms.
Convert IV Files to FBX, glTF, OBJ, and More
