Oniro Srl is a deep-tech startup transforming the way we design and manufacture advanced structures through a disruptive approach to 3D printing: Foam Additive Manufacturing® (FAM).
FAM integrates physical blowing agents into the extrusion of thermoplastic materials, forming cellular structures with controlled pore distribution. The process is digitally programmable, allowing users to adjust foam density voxel-by-voxel.
This means that the same object can have different internal zones soft, rigid, insulating, or energy-absorbing all created seamlessly without assembly or adhesives.
Schematic and microstructural view of FAM.
The diagram illustrates how physical blowing agents expand the thermoplastic during extrusion, forming a foamed strand. Microscopic cross-sections compare a solid filament with a foamed one, highlighting the significant internal porosity and weight reduction achievable through FAM without compromising external dimensions or printability.
FAM is not just a new printing technique it’s a new material paradigm. By integrating physical blowing agents directly into the extrusion process, Oniro enables real-time control over the porosity and morphology of thermoplastic materials during deposition.
This allows the creation of lightweight structures with precise, spatially tailored density gradients something that was previously only achievable with multi-material composites, chemical foaming, or costly post-processing.
