Understanding 3MF and PRT file formats
3MF (3D Manufacturing Format) is a modern file format developed by the 3MF Consortium for 3D printing. It stores 3D models, textures, materials, and other data in a compact, open, and extensible XML-based structure, making it ideal for additive manufacturing workflows.
PRT files are proprietary 3D part files used by various CAD software, most notably Siemens NX and PTC Creo. These files contain detailed part geometry, features, and sometimes assembly information, making them essential for engineering and manufacturing processes.
How to convert 3MF to PRT
Direct conversion from 3MF to PRT is not always straightforward due to the proprietary nature of PRT files. The process typically involves importing the 3MF file into a CAD application that supports both formats and then saving or exporting it as a PRT file.
Recommended software for 3MF to PRT conversion
- Siemens NX: Import the 3MF file using File → Import, then save the part as a PRT file with File → Save As.
- PTC Creo: Open the 3MF file via File → Open, then export as PRT using File → Save As.
- Autodesk Fusion 360: Import the 3MF file, then export to a compatible format (such as STEP or IGES), and finally open and save as PRT in Siemens NX or Creo.
For users without access to these CAD programs, consider using online conversion services like CAD Exchanger or Autodesk Viewer to convert 3MF to an intermediate format (e.g., STEP), then import into Siemens NX or Creo to save as PRT.
Important considerations
- Data loss: Some features or metadata may not transfer perfectly between formats.
- Software compatibility: Ensure your CAD software version supports 3MF import and PRT export.
- Licensing: PRT is a proprietary format; conversion may require a licensed version of Siemens NX or PTC Creo.
