Additive Manufacturing and machining of large-format titanium aeronautic components with structural requirements

The main objective of the FATIMA project is to develop a global strategy focused on additive manufacturing (AM) and subsequent machining, DfAMM (design for additive manufacturing & machining), of large titanium parts for aeronautics with improved structural properties, covering all stages of the value chain (design, AM, and machining). The main outcome of the project will be a comprehensive design methodology for large Ti parts printed by a laser beam and wire directed energy deposition (DED-LB/Mw) process, which will include the improvement of the microstructure obtained in the DED-LB/Mw printing process with the aid of an ultrasound (US) system; a macro-scale finite element modelling strategy to support defect-free manufacturing; and machining strategies for large-format structural titanium preforms printed by DED-LB/Mw.
AIMEN will collaborate with INESPASA in supporting the comprehensive design of the titanium part, covering additive manufacturing and machining, focusing its work primarily on improving the microstructure and performance of titanium printed using the US-assisted DED-LB/Mw process, together with finite element simulation of the process as a support tool for defect-free fabrication. Finally, it will be responsible for printing the large-format titanium demonstrator thanks to the implementation of these improvements and validation of the methodology deployed.
