Why we like it

Earns its place as a single-format bridge that keeps conversion in the cloud, so Blender stays lightweight while .3mf files round-trip between the app and common slicers. A portion of proceeds goes to the Blender Foundation.

What is Super3D Import & Export .3Mf?

Super3D Import & Export .3Mf is a focused Blender add-on for moving .3mf files in and out of the scene. The .3mf format is an XML-based 3D-printing container backed by the 3MF Consortium that carries color, materials, textures, multi-part assemblies and printer build-plate information in a single package, going beyond what STL holds.

The add-on installs dedicated File menu entries for import and export. Conversion runs through the Super3D cloud service, so Blender stays lightweight. On import, the add-on uploads the file, then downloads and merges the result into the active scene. On export, the scene is written to OBJ on the main thread, converted to .3mf via Super3D and saved to disk.

Imports bring in printable parts as separate objects, per-part color and material assignments where present, and build-plate transforms so layout matches the slicer. Embedded textures are extracted as image data when present, while slicer-specific data such as supports and infill is descriptive only and not regenerated. On export, procedural shaders are baked to per-vertex or per-material color, and non-manifold geometry should be repaired in Blender first.

Who is Super3D Import & Export .3Mf best for?

Super3D Import & Export .3Mf is best for 3D-printing creators polishing printable models in Blender, and designers or Bambu Studio, PrusaSlicer and Cura users bringing slicer projects into Blender for lighting and marketing renders.

How much does Super3D Import & Export .3Mf cost?

Super3D Import & Export .3Mf is completely free to download and use.

Frequently asked questions

Which Blender versions does Super3D Import & Export .3Mf support?

Super3D Import & Export .3Mf is tested on Blender 4.2 through 5.1, and its legacy bl_info entry covers Blender 4.0 and later. It installs as a focused add-on with GPL licensing and adds dedicated File menu entries for importing and exporting .3mf files. Because conversion runs through the Super3D cloud service rather than a local library, Blender stays lightweight, and you only need a supported Blender build and an internet connection to use it.

Do I need the 3MF Consortium spec installed to use Super3D Import & Export .3Mf?

Super3D Import & Export .3Mf does not require the 3MF Consortium spec to be installed. Conversion runs in the cloud through the Super3D service, so all you need is Blender and an internet connection. On import, the add-on uploads your .3mf file, then downloads and merges the result into the active scene. On export, the scene is written to OBJ on the main thread, converted to .3mf via Super3D, and saved to disk.

Will my mesh be print-ready after exporting back to .3mf with Super3D Import & Export .3Mf?

Super3D Import & Export .3Mf writes manifold-friendly meshes into the .3mf package, but print-readiness depends on the manifoldness of your geometry. The add-on does not auto-repair non-manifold geometry, so run Mesh → Clean Up in Blender before exporting to avoid printing failures. Procedural Blender shaders are baked to per-vertex or per-material color on export, and per-object material colors carry through. Slicer-specific data such as supports and infill is not regenerated by the add-on.

Does Super3D Import & Export .3Mf support multi-color models?

Super3D Import & Export .3Mf supports multi-color models through per-object material color, which round-trips on import and export. Per-vertex color requires extra setup in your slicer. On import, per-part color and material assignments are preserved where present, and embedded textures are extracted as image data when available. On export, per-object material colors are written into the .3mf package, and procedural shaders are baked down to per-vertex or per-material color.

Can I install Super3D Import & Export .3Mf alongside other Super3D format add-ons?

Super3D Import & Export .3Mf can be installed alongside other Super3D format add-ons without conflicts. Each format ships as a separate extension with its own ID and operator names, so they coexist. This add-on is a single-format slice covering .3mf only, and it's listed as free here, so check the developer's page for current licensing. A portion of proceeds supports the Blender Foundation's open-source development.
