What is a STL file?

STL (Stereolithography) is one of the most common 3D file formats used for 3D printing. It describes the surface geometry of a 3D object without including color, texture, or other attributes.

STL files are supported by virtually all 3D printers and modeling software. They are lightweight and easy to process, making them the go-to choice for rapid prototyping and additive manufacturing.

How to open STL files

STL files can be opened in most 3D modeling and slicing programs such as Blender, Cura, TinkerCAD, and Fusion 360. They are essential for 3D printing workflows.

Use AnyConv to convert STL files to formats like OBJ or STEP for further editing or integration with CAD systems.

What is a IGES file?

IGES (Initial Graphics Exchange Specification) is a long-established format used to exchange CAD data between different systems. It supports wireframes, surfaces, and solid models and is often used in mechanical engineering and product design.

Although somewhat superseded by STEP, IGES is still widely supported by CAD tools and remains a standard for legacy data and compatibility between engineering systems.

How to open IGES files

IGES files can be opened using CAD software like AutoCAD, SolidWorks, FreeCAD, and Rhino. They are ideal for exchanging engineering data across platforms.

You can convert IGES files to STEP or STL using AnyConv or CAD tools for downstream workflows like 3D printing or simulation.

Key facts about IGES

  • Full name: Initial Graphics Exchange Specification
  • Extension: .iges
  • MIME type: model/iges
  • Developed by: U.S. Air Force
  • Initial release: 1980
