STL 3D Format STL Converter
The Stereolithography (STL) format is one of the oldest and most widely used 3D formats. Primarily used for 3D printing, it is supported by virtually every 3D printing and slicing program, making it a popular choice for general 3D printing needs. If you’re unsure of a format to use for printing, STL is a safe bet until you know exactly what you want.
You can open STL files in Blender, MeshLab, Fusion360 and many other programs, and the format works across Windows, macOS, Linux, and even mobile platforms. If you want to store material or colour data in your file, however, you may need to look for an STL alternative, as this format only supports geometry data. For mocking up quick prototypes, though, you can’t get much better than STL, with its minimalism and near-universal support.

3MF 3D Format 3MF Converter
The 3D Manufacturing Format (3MF) is an XML-based file that stores information useful for 3D printing. It was developed and established by the 3MF Consortium with the goal of efficiently storing 3D printing data to be used across many different pieces of software. As 3D printing has become more effective and prevalent, a more standardised file type was necessary. Although the STL file format is more widely used among legacy and hobbyist users, 3MF is quickly becoming the industry choice for modern use cases.
If you just want to view the file, Windows has a built-in app called Windows 3D Builder that will do the trick. If you want to edit a file before you print it, 3MF can be used with software such as Microsoft 3D Builder, Autodesk Fusion 360, and SOLIDWORKS.
