The duo has now received the go-ahead from the relevant authority, Austro Control, for the component\u2019s certification \u2013 a first in Austrian aviation history: \u201cIn this industry, the requirements for safety and reliability are extremely high. Every component must undergo comprehensive material testing to ensure it can withstand a wide range of stresses. This means that not only the mechanical properties but also resistance to extreme weather conditions are tested. In addition, material compatibility plays a crucial role. This certification is therefore of the highest significance,\u201d explains FACC project manager Fabian Mayer.<\/span> <\/span><\/span><\/p>\n A major impact<\/b> \u201cThis design freedom makes it possible to further reduce the weight of components whilst maximising their strength,\u201d says the 3D printing expert. As a result, more efficient, lighter and higher-performance aircraft components would be produced, Herzig emphasises. In concrete terms, this means: \u201cThe projected fuel savings of around two and a half to five per cent lead, depending on the size of the aircraft and its annual flight time, to a reduction in CO\u2082 emissions of several tonnes per year \u2013 per aircraft,\u201d Herzig explains. <\/span><\/p>\n Investment in 3D printers<\/span><\/b>![\"A](\"https:\/\/mhcnc.com\/wp-content\/uploads\/2025\/05\/Gross-Winglet-1.jpeg\")
\nAs unassuming as this component may seem, its impact is significant: <\/span><\/b><\/span>This small curve \u2013 now made of aluminium \u2013 at the tip of the wings makes the aircraft significantly quieter, more economical and more efficient. \u201cThanks to additive manufacturing, we are no longer bound by the limitations of traditional tools and moulds. Instead, we can create organic, flowing designs that are optimised for aerodynamic efficiency in aviation,\u201d explains Patrick Herzig, Managing Director of M&H. <\/span><\/p>\n
\nAnother advantage of additive manufacturing is that, whilst traditional manufacturing processes leave visible weld seams or joints, 3D-printed parts can be produced in a single piece with a smooth surface. \u201cThis is particularly important in areas where not only function but also appearance is key \u2013 as is the case with business jets,\u201d says Herzig. In future, FACC will be installing these innovative components in business aircraft. M&H is determined to further establish itself in this business sector and to continue developing the technology. \u201cThe range of applications for 3D-printed components in aviation is growing steadily.\u201d To this end, the company has recently invested in a new metal 3D printer from Nikon SLM: this is already the second machine of its kind at M&H and will further expand the company\u2019s manufacturing capabilities, according to the managing director. <\/span><\/p>\n
