Rhinoceros 3D (3DM) File Format
The 3DM file format is the native format for Rhinoceros 3D (Rhino), a leading NURBS-based 3D modeling software used across industries like architecture, engineering, and industrial design. 3DM files accurately store mathematical representations of curves, surfaces, solids, and meshes, making them essential for precision 3D modeling and CAD workflows.
Key Features of 3DM Files
- NURBS Geometry: Supports precise, smooth surfaces critical for advanced design and engineering projects.
- Polygonal Meshes: Stores tessellated 3D models ideal for rendering, simulation, and 3D printing workflows.
- SubD Surfaces: Allows flexible, editable subdivision modeling for organic shapes and complex surfaces.
- Instance References: Saves memory by creating linked object instances, optimizing large and detailed models.
Convert 3DM Files Seamlessly
Autoconverter and Autoshaper simplify 3DM file conversion to popular formats like STEP, IGES, OBJ, STL, and DWG. Automate the export of 3DM polygon meshes for 3D printing, or preserve NURBS data for engineering-grade CAD models. Save files in legacy (Rhino 2.X - 7.X) or latest Rhino 8.X formats to ensure compatibility across all project environments.
3MF (3D Manufacturing Format) File
The 3MF (3D Manufacturing Format) is an open-source XML-based file format developed by the 3MF Consortium - an industry group composed of leading companies in the 3D printing sector. 3MF was specifically designed to address the limitations of older formats like STL, offering a richer, more extensible framework for modern additive manufacturing workflows. With 3MF, you can store not just the model geometry, but also color, textures, material properties, and metadata within a single file.
Key Advantages of 3MF Over STL
Unlike traditional STL files that store only basic 3D geometry, the 3MF format provides a wide range of enhanced capabilities:
- Color Support: Enables full-color 3D printing by defining colors per triangle or per object, enhancing model realism.
- Transparency and Opacity: Supports adjustable transparency for parts of the model, allowing the creation of translucent and transparent objects.
- Texture Mapping: Associates 2D image textures with 3D surfaces, producing highly detailed and visually realistic prints.
- Embedded Metadata: Includes detailed information such as author, copyright, licensing, description, and more—improving project management and file documentation.
3MF File Conversion and Workflow
Our Autoconverter and Automesher Application offer full support for importing, exporting, and converting 3MF files. Powered by the official lib3mf library, our software ensures high compatibility and reliable file processing across various 3D printing and CAD workflows.
Note: A current limitation of the 3MF format is its lack of support for nested group hierarchies. When converting complex 3D models with subgroup structures, the hierarchy will be flattened during export. Nevertheless, 3MF remains a highly advanced and preferred format for professional 3D printing, providing significant advantages over older standards like STL.
