The objective of the project was to develop an innovative prototyping process based on inkjet of a nanodoped ink for materials functionalization.


The project allowed Aviospace to develop (TRL 6) a full process of materials functionalization by means of ink-jet printing, including: 

  • Case-by-case nanoparticle-based ink design and formulation (e.g. both conductive and dielectric inks)
  • Printed pattern optimization and printing process set-up
  • Wide range of possible substrates (e.g. ceramic, metallic, composites)
  • Post-printing thermal treatments

This technology involve the use of a stable and repeatable process, which makes use of less galvanic treatment and waste production. Moreover, mass savings and lower manufacturing costs, as well as the possibility to deal with 3D shapes, make it a competitive alternative to traditional manufacturing techniques.

Product performance – Inkjetted heater device:


  • Power output > 10 W
  • Sample heating rate = 10 °C / min @ 22 V
  • Power density > 1000 W/m2
  • Double redundancy pattern
