Convert 3DM to 3MF

The 3DM file extension, standing for "3D Model", is associated with the openNURBS initiative, which facilitates the exchange of 3D geometry across CAD, CAM, CAE, and computer graphics software. Developed by Robert McNeel & Associates, it serves as the native format for Rhinoceros (Rhino) software. Introduced to address interoperability challenges, 3DM files store precise 3D models using NURBS (Non-Uniform Rational B-Splines) and polygon mesh representations. This format is widely adopted due to its open-source nature, enabling developers to read and write 3DM files without proprietary restrictions, thus promoting seamless data sharing in 3D modeling workflows.

The 3D Manufacturing Format (3MF) is a file extension used in additive manufacturing, commonly referred to as 3D printing. Developed by the 3MF Consortium, it provides a streamlined and improved format over traditional STL files. Introduced in 2015, the 3MF format supports richer data representation, including color, material, and other properties, ensuring better interoperability and more accurate print results. Its adoption has facilitated enhanced efficiency and precision in the 3D printing industry, making it a preferred choice for professionals in the field.
