    This work presents a spray system prototype, which was made for the needs of thin-film coatings fabrication. It is based on a common airbrush and parts of an old broken inkjet printer. Transforming creatively waste or useless materials to something new is called upcycling. It is an inalienable part of the green economy, a philosophy a few industries have already followed. Upcycling an inkjet printer to create a low-cost prototype machine is proof that a low carbon footprint can be achieved in many ways and not only by recycling the increasing waste. We can reduce waste, and engineers following this philosophy can also develop their creativity. In addition, were chosen to be presented three representative experiments executed using the spray system prototype. The first experiment is a fabrication of a transparent flexible electrode using silver nanowires and graphene. The second experiment is an alternative fabrication of a Hole Transport Layer (HTL) for a perovskite photovoltaic structure. And the last one is a two-step fabrication of a flexible conductive electrode using graphene oxide and then converting it to reduced graphene oxide. Finally, it is also presented the fabrication and characterization equipment.
