What is a CTM file?

CTM (Compressed Triangle Mesh) is a file format designed for efficient compression and storage of 3D triangle mesh data. It aims to reduce file size while preserving geometric accuracy and topology.

CTM is used in real-time applications where fast loading and transmission of 3D models is important, such as in WebGL-based viewers and mobile apps.

How to open CTM files

CTM files can be opened using OpenCTM tools or viewers, and are often used in applications where mesh compression is essential for performance.

Convert CTM to more common formats like STL or OBJ using AnyConv or the official OpenCTM converter tool for better compatibility.

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.
