The use of 3D printed metal structures is taking a very fast ramp-up in industry. General Electric has demonstrated the possibility of printing titanium fuel injectors for their LEAP engine, EADS has printed a nacelle hinge bracket for the Airbus A320, Boeing is printing plastic inlet ducts for high-altitude aircrafts, hip implants and other prosthetics are exploiting the design freedom of additive manufacturing (AM),...
Additive manufacturing of titanium alloys yields great potential for the aerospace industry (and others) as it allows the generation of geometrically complex structures with high specific strength, low density and high corrosion resistance. However the inspection of such 3D printed components is almost impossible with traditional Non-Destructive Testing (NDT) techniques because of the typical complex geometries and internal cavities. A very interesting alternative is PCRT (Process Compensated Resonance Testing), a high-frequency vibration technique that tries to detect defects by isolating very small shifts in the resonance spectrum at very high frequencies.
In this Postdoctoral position, it is the purpose to build a PCRT set-up for inspecting 3D printed metal parts with complex geometry, to implement the data-acquisition and to develop advanced post-processing tools for identification of defects in the frequency domain. The research is in close collaboration with Materialise and Siemens, two leading companies in the development of 3D printing. The project is funded by SIM-Flanders (Strategic Initiative Materials in Flanders).
Only candidates with a PhD degree or equivalent experience should apply. The candidate should have a strong background in vibration techniques and data analysis in frequency domain.
