The 3MF (3D Manufacturing Format) has become one of the most modern and flexible formats in additive manufacturing. It can store not only the geometric mesh of your model, but also materials, textures, colors, print parameters, and metadata – all neatly packaged inside a compressed ZIP-based container.
However, despite its advantages, many 3D printers and slicing tools still rely on the STL format. STL remains the simplest and most widely supported geometry-only standard in 3D printing. For this reason, converting 3MF to STL is a frequent and necessary step in many production and prototyping workflows.
In this tutorial, we’ll look at how reaConverter processes 3MF files, how to control the conversion quality using Level of Detail, and how to export clean STL files ready for slicing.
