In contemporary manufacturing, additive manufacturing, commonly known as 3D printing, and sustainability are increasingly recognized as intertwined concepts. Numerous studies and practical applications have repeatedly demonstrated that 3D technology offers significant environmental advantages over conventional manufacturing methods. These benefits are manifold: from substantial reductions in production times and material consumption, as only the precise amount of material needed is used, to minimizing waste and lowering energy expenditure during the manufacturing process. Furthermore, additive manufacturing processes often result in lower emissions of harmful gases compared to traditional techniques. Despite these advancements, the journey towards comprehensive sustainability, particularly within the highly demanding aeronautical industry, still presents considerable challenges and opportunities. The statistics underscore this urgency: according to data from the European Union, air transport accounts for approximately 2% of the staggering 36 billion tons of CO2 generated annually by human activities worldwide. This figure, though seemingly small, represents a growing challenge as air travel continues to expand globally. It is precisely for these reasons that 3D printing has been positioned as a central pillar of the HERON project, leveraging the innovative solutions pioneered by the Aitiip technology center to fundamentally alter these environmental impact figures.
