Engineering Solutions Across Industries

From CAD to delivery, we turn thermoplastic 3D-printed parts solid or foamed (Foam Additive Manufacturing®) into industrial products, from prototypes to series production.

Lightweight Structures with Graded Monomaterial Foams

Oniro manufactures density-graded thermoplastic foam components for marine structures using Foam Additive Manufacturing® (FAM). We turn already certified thermoplastics into ultra-light foams while printing, enabling structural and buoyant zones in a single part — with fewer assembly steps and a clean supply chain.

Up to 80% weight reduction

FAM transforms standard thermoplastics into ultra-light foams during printing, reducing mass while keeping geometry and function integrated.

Process ASA, r-PET, PA6, PETG and high-performance polymers such as PEEK and PEI without introducing chemical additive or new materials, avoiding extra certification and supply-chain changes.

Density and stiffness can be tuned voxel-by-voxel (0.2–0.9 g/cm³), enabling structural and buoyant zones in the same continuous print.

No adhesives or mixed cores: a closed-loop monomaterial structure designed for recycling at end-of-life.

What we build

Production parts and core kits for marine structures, including:

  • Interior panels & bulkheads 
  • Hull cores / sandwich core geometries
  • Buoyancy modules 
  • Protective housings

Lightweight Composite Cores and Monomaterial Sandwich Components

Oniro manufactures density-graded thermoplastic foam cores and lightweight components for aerospace structures using Foam Additive Manufacturing® (FAM). We engineer localized stiffness, thickness and bonding surfaces to match your load cases and manufacturing route delivering repeatable, production-oriented parts from prototype to series supply.

Up to 80% weight reduction

FAM transforms standard thermoplastics into ultra-light foams during printing, reducing mass while keeping geometry and function integrated.

Density and stiffness can be tuned voxel-by-voxel (0.2–0.9 g/cm³), enabling structural and buoyant zones in the same continuous print.

Supports aerospace thermoplastics such as PEEK/PAEK (PEEK, PEKK, LM-PAEK), PEI (ULTEM™), PPS and sulfone polymers (PPSU/PSU/PES).

Controlled parameters, defined density windows, and documentation packages to support your validation/qualification workflow.

What we build

Production-ready core kits and lightweight structures, including:

  • Sandwich panel cores 
  • Interior components 
  • UAV / UAM fairings & enclosures 
  • Equipment housings & ducts

Lightweight Functional Systems in Recyclable Thermoplastics

Oniro manufactures lightweight thermoplastic components with engineered porosity using Foam Additive Manufacturing® (FAM). We deliver repeatable, project-ready parts where weight reduction, acoustic/thermal function, and customization are required from one-offs to series supply for contract and building projects.

Weight reduction to simplify installation

Lightweight components reduce handling effort and can lower structural load requirements (application-dependent).

Porosity and density are engineered to target sound absorption damping and thermal insulation, while maintaining stiffness where needed.

Net-shape printing enables freeform surfaces, variable thickness, ribs, and integrated mounting features without molds.

Thermoplastic solutions support circular strategies and simplified end-of-life management (project-dependent).

What we build

Project-ready components for interiors and building systems, including:

  • Acoustic panels & baffles
  • Lightweight partitions & wall elements
  • Furniture cores & structural inserts 
  • Custom functional elements

Programmable Impact Protection in Thermoplastics

Oniro manufactures impact-absorbing thermoplastic components with engineered, density-graded porosity using Foam Additive Manufacturing® (FAM). We design the internal architecture to meet target energy absorption, thickness, weight, and fit constraints  delivering repeatable parts from prototypes to pre-series and production supply.

Higher energy absorption

Density-graded structures can deliver up to +47% energy absorption while keeping weight and thickness under control.

Density and stiffness can be tuned voxel-by-voxel (0.2–0.9 g/cm³), enabling structural and buoyant zones in the same continuous print.

Monomaterial parts reduce assembly complexity (no mixed foams/cores), supporting simpler end-of-life management.

Controlled process parameters and defined density windows support consistent mechanical response across batches.

What we build

Production-ready protective components and inserts, including:

  • Helmet liners
  • Body protection pads 
  • Sports protective inserts
  • Footwear insoles & damping inserts

High-Fidelity Replicas for Exhibitions and Accessibility

Oniro delivers full-scale tactile replicas and exhibit-ready models combining high-accuracy 3D scanning and precision additive manufacturing. We support museums, institutions, and cultural projects with repeatable, documented workflows for accessibility programs, touring exhibitions, and conservation-friendly display solutions.

High-accuracy digital capture

3D scanning with sub-millimetric accuracy (project-dependent) to preserve geometry and fine details.

Full-scale printing optimized for stability, handling, and display—suitable for tactile interaction and public-facing use.

Post-processing and hand finishing to achieve the required surface quality, color matching, and touch-safe textures.

Replicas designed for tactile tours, inclusive education, and multi-site installations while protecting originals.

Clear deliverables, documentation, and project coordination aligned to institutional requirements and timelines.

What we build

End-to-end replica production for cultural heritage projects, including:

  • 3D scanning & digital model preparation
  • Full-scale replicas (1:1) or scaled models
  • Post-processing & finishing
  • Mounting / handling solutions

This project was made possible thanks to the funding received under the “Campania Startup 2023” call for proposals, promoted by the Regional Department for Research, Innovation, and Startups (UOD05 – Regione Campania), as part of the Regional Operational Programme FESR 2014–2020 – Specific Objective 1.1 – Action 1.1.3.
This strategic support enabled us to formalize Oniro S.r.l. and initiate the industrial development of our core technology: Foam Additive Manufacturing (FAM), an advanced 3D printing process capable of controlling the internal morphology and density of thermoplastic materials through real-time physical foaming.

The project presented under the Campania Startup 2023 program aimed to demonstrate the potential of mono-material structural components manufactured in a single step, without adhesives or post-processing, offering high mechanical performance and full recyclability. Applications range from lightweight sandwich panels for transportation and aerospace to bio-based foamed parts for sustainable consumer products.
Thanks to this grant, we were able to invest in early-stage prototyping, intellectual property protection, and validation of our approach—laying the foundation for what is now an operating startup with international ambitions and solid technical credibility.
