￼AERONAUTICS Lightweighting: less fuel, less C02 L NANOTUND3D: the new material that will revolutionize the aerospace sector Several estimations show that each kg of weight redu- ced in the aircraft could save between 0.02 and 0.04 kg of fuel per hour1, which could lead to each kg of weight saved could save 4 t of fuel along the aircraft service life and avoid the emission of 12.5 t of CO2. > Luis Portolés Griñán, Strategic Markets and Exploitation Manager of Aidimme 28<< ightweighting is a key issue in most transport applications, and particularly in the aero and space sectors. Engineers from those markets are always looking for new material and manufacturing processes which enable disruptive designs with the goal to reduce the weight of the components. Can you imagine a new generation of material which allows reducing the weight of the structural parts from 40 up to 90%? This is the goal pursuing by Nanotund3D. Nanotund3D is the result to combine two disruptive technolo- gies: nanomaterials and Additive Manufacturing (AM). Nanotund3D will be a new generation of material for AM, which consists of a nano-enhanced Titanium alloy in powder as feeds- tock suitable to be processed by most common metal powder bed fusion technologies such as Electron Beam Melting (EBM) and Selective Laser Melting (SLM). Expected improvements of between 15 and 40% of mechanical properties (tensile, hardness, fatigue, wear, high T behaviour) , together with the bene ts of AM (i.e. topologic optimization and freeform manufacturing) sum up a dramatic lightweighting of the manufactured components, with an estimated saving of mate- rials between 40 and 60%, with respect to traditional processes. Particularly attractive features for a sector such as aerospace, according to the partners from Nanotund3D. The Nanotund3D goal is to develop a novel and stronger Ti-composite for printing parts to y higher, longer, cleaner and at lower cost for manufacturer and consumer in all aerospace applications.
