**The 3MF Format: A New Standard for Additive Manufacturing**

In the landscape of additive manufacturing, the 3MF format represents a fundamental evolution compared to traditional formats. Developed within the context of an industrial consortium founded in 2015, 3MF was created with the intent to overcome the limitations of historical formats, such as STL, which often result in data loss and compatibility issues between various design software and production machines.

Unlike its predecessors, the 3MF format can encapsulate, within a single file, all the necessary information to describe a 3D model. This capability goes beyond simple geometric representation: 3MF also retains complex data such as colors, materials, textures, and advanced lattice structures, allowing for a much more faithful and rich representation of the designed object.

Recently, the publication of the ISO/IEC 25422:2025 standard provided an official definition of the fundamental specifications of the 3MF format and its extensions, which focus on various aspects such as materials and properties, the production process, slicing, and the management of secure content. This development marks a significant step towards the integration of globally recognized standards in the field of additive manufacturing.

**A Journey of Collaboration**

The standardization of the 3MF format is the result of a long collaborative process among numerous key players in the industry. Almost a decade ago, the pioneers of this project embarked on a journey to create a consensus on the importance of having a unified and high-quality file format. Over time, other significant companies in the sector joined this initiative, forming a consortium that now counts more than 35 members. The support for the 3MF format extends to over 100 software applications, making this technology accessible to an ever-growing number of professionals and businesses.

**Reception in the Industry**

The announcement that the 3MF format has been adopted as an ISO/IEC standard has generated excitement among industry leaders, who see this decision as an opportunity to drive innovation and the large-scale adoption of additive manufacturing technologies. The industrial community perceives this standard as a catalyst for interoperability, capable of ensuring a more solid and integrated future for the sector, which continues to evolve rapidly.

Because of its versatility, 3MF is considered the reference format for creating models destined for a wide range of applications, from desktop FDM printers to high-end machines used in strategic industries such as aerospace. This ability to adapt to such diverse contexts represents a significant advantage in a constantly evolving sector.

**A Safe and Sustainable Future**

The international recognition that the 3MF format has received through ISO certification represents an important milestone for the additive manufacturing industry. It constitutes a standard framework that facilitates the safe and accurate transfer of design intentions, production data, and process parameters. In this way, the foundations are laid for increased trust among the various market players, promoting greater integration and cooperation.

The ability to manage complex information and ensure interoperability among different systems will be crucial in supporting the new challenges facing the industry and ensuring its continued growth.

**Conclusion**

The 3MF format emerges as a strategic solution in an increasingly interconnected and dynamic technological context. With the adoption of international standards and a growing consensus among the key players in the industry, the prospects for additive manufacturing are extremely promising.
