A1 Guerrero-Vacas, Guillermo Rafael A1 Rodríguez Alabanda, Óscar A1 Martín-Fernández, Francisco de Sales A1 Martín-Sánchez, María Jesús K1 Acero inoxidable - Fabricación K1 Impresión 3D AB This study compares subtractive manufacturing (SM) and additive manufacturing (AM)techniques in the production of stainless-steel parts with non-stick coatings. While subtractivemanufacturing involves the machining of rolled products, additive manufacturing employs the FFF(fused filament fabrication) technique with metal filament and sintering. The applied non-stickcoatings are commercially available and are manually sprayed with a spray gun, followed by a curingprocess. They are an FEP (fluorinated ethylene propylene)-based coating and a sol–gel ceramic coating.Key properties such as surface roughness, water droplet sliding angle, adhesion to the substrate andwear resistance were examined using abrasive blasting techniques. In the additive manufacturingprocess, a higher roughness of the samples was detected. In terms of sliding angle, variations wereobserved in the FEP-based coatings and no variations were observed in the ceramic coatings, with aslight increase for FEP in AM. In terms of adhesion to the substrate, the ceramic coatings applied in theadditive process showed a superior behavior to that of subtractive manufacturing. On the other hand,FEP coatings showed comparable results for both techniques. In the wear resistance test, ceramiccoatings outperformed FEP coatings for both techniques. In summary, additive manufacturing ofnon-stick coatings on stainless steel showed remarkable advantages in terms of roughness, adhesionand wear resistance compared to the conventional manufacturing approach. These results are ofrelevance in fields such as medicine, food industry, chemical industry and marine applications.
