What is a 3MF file?
3MF (3D Manufacturing Format) is a modern, XML-based format developed by the 3MF Consortium led by Microsoft. It was designed specifically for 3D printing and supports color, material properties, and full-fidelity geometry in a compact file.
3MF aims to replace STL by solving its limitations and is supported by many slicers, printers, and design tools like Microsoft 3D Builder and Ultimaker Cura.
How to open 3MF files
3MF files can be opened with Microsoft 3D Builder, Ultimaker Cura, PrusaSlicer, and other 3D printing software. Many CAD tools also support importing 3MF models.
AnyConv allows you to convert 3MF files to STL, OBJ, or other formats suitable for printing or modeling.

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.
