The 3MF Consortium Welcomes Spherene as an Associate Member.
Spherene develops software for controlling the internal geometry of 3D printed parts, using their Adaptive Density Minimal Surfaces (ADMS) technology to optimize density, thickness, surface bias, and orientation across a part’s interior. Their tools integrate directly into existing CAD workflows, enabling engineers and designers to define internal structures with the same precision applied to external geometry.
”Joining the 3MF Consortium is the natural next step in our innovation journey. We believe that open, interoperable standards are key to unlocking the full potential of additive manufacturing, and by becoming part of 3MF, we can help ensure that intelligent internal structures are seamlessly communicated and standardized across every printer, material and workflow — for the benefit of the entire industry.
Claudio Nessi,CEO of Spherene
Communicating complex internal geometry across software, hardware, and material workflows requires a data format capable of representing more than surface mesh. The 3MF Volumetric Extension, which supports voxel and implicit (Signed Distance Function) representations, provides the foundation for encoding the kind of volumetric structural data Spherene generates. Spherene’s membership reflects a recognition that standardized, open data exchange is a prerequisite for intelligent internal structures to be reliably reproduced across printers and materials.
”Spherene is developing one of the most innovative softwares for controlling internal part geometry, and properties in additive manufacturing today. The potential of that work has long been constrained by file formats that cannot adequately or efficiently represent volumetric and implicit geometry.
With their adoption of the 3MF implict format, the file size for a complex design can be smaller than the screenshot of that same part, with no discretisation.
We are pleased to welcome them to the 3MF Consortium and look forward to working together to close that gap.

”Spherene is the CAD for the inside — giving engineers and designers full control over the internal structure of their 3D printed parts.
Powered by our Adaptive Density Minimal Surfaces (ADMS) technology, Spherene intelligently optimizes density, thickness, surface bias and orientation to deliver components that are lighter, stronger, better and more efficient, while reducing material use, design and production time — seamlessly integrated into any CAD workflow
Claudio Nessi,CEO of Spherene
Spherene currently integrates as a plugin into nTop, Autodesk Fusion, and Rhino/Grasshopper, the three design environments that also support 3MF, and where the much of the serious computational DfAM work happens today.
In each case, ADMS structures are generated directly within the host environment without requiring intermediate export steps.

The challenge that has persisted across all three workflows is what happens downstream: once a part leaves the design environment, the internal geometry it carries must be accurately communicated to slicers, printers, and material systems in a way that preserves design intent.
That is precisely the problem 3MF is positioned to solve. The format’s Volumetric Extension, which supports implicit and voxel-based geometry representations, provides the data foundation needed to carry Spherene’s adaptive density fields from design through to fabrication without loss of fidelity.
Spherene’s membership in the consortium brings a developer with direct experience of that gap to the table, where the specification is written.
We look forward to working with Spherene as they contribute to the development of open standards that extend the communicable design intent of 3MF beyond the surface and into the interior of parts.
