Why our structures are so stable
We call our structures ADMS, short for «Adaptive Density Minimal Surfaces». Just like other, well-known minimal surfaces like the Gyroid, ADMS are doubly curved at each point such that the mean curvature is zero at every point.
ADMS are at the same time controlled, regular, aperiodic and random, which makes for structures that are generally isotropic.
Unlike other structures, both spheres and ADMS show no spikes in the distribution of the orientation of their surface, which means they perform equally well in all directions. Our geometry is closely related to that of the sphere — (this is why our company is called spherene!)
Why our structures can be optimized for simultaneous requirements
Unlike other minimal surfaces, our ADMS are freely configurable thanks to their inherent properties:
- structural density and wall thickness are locally adjustable, driven by our proprietary algorithm
- geometry generation guided by internal multi-physics simulation (FEniCS)
How we enable support free printing
Zero mean curvature means that every point in the print is supported by a doubly curved surrounding. You can print our ADMS structure support free with any printer on any print method!
Why it is easy to evacuate powder, slurry or liquids
Our structures consist always of two interwoven,
yet separate spaces:
- full access open structure, or shell with evacuation holes
- continuous curvature, no nooks and crannies
- special micro-surface characteristics provide turbulence that increase cleaning efficiency
"The spherene technology introduces a completely new way of thinking about how components can be designed and laid out, which has been lacking until now."
"It’s ideal - it's the inverted sphere geometry!"
