Congratulations Fynn-Henrik Duus on your master thesis! ✨ 'Concept development for the integration of mechanically highly resilient lattice structures in structural optimization using nTop's "implicit field technology" for additive manufacturing processes.' Awesome way to apply Field Optimization to a part like the GE Jet Engine Bracket. Thank you to Jaco Beckmann and Jens Telgkamp for sharing this work and advancing computational design methods!

The idea was to identify new component designs for improved sustainability through greater design freedom by using additive manufacturing. Therefore, the challenge was awarded to redesign an existing titanium bracket for an aircraft engine in order to minimize aircraft weight, thereby improving fuel consumption and CO2 emissions. In the end, the bracket designed by M. Arie Kurniawan from Indonesia was chosen as the 2013 winner from almost 700 designs submitted from 56 countries. More than ten years later, advanced structural optimization software has made it possible to create new, improved lightweight designs with integrated lattice structures. By using nTop's advanced field optimization approach, not only was it possible to reduce the weight by over 83% compared to the original bracket. In direct comparison to the winning component from 2013, the von Mises comparative stresses were reduced by almost 28% while maintaining the same weight. Consequently, software developments in recent years have enabled completely new design solutions in the field of lightweight construction and heat exchanger improvements through the use of perfectly designed internal lattice structures combined with the high design freedom offered by additive manufacturing processes. This impressive development over the last ten years raises an exciting question: What will be possible in another ten years from now on? If you are interested in the nTop software, Bradley Rothenberg will present his engineering design software at the HAW Hamburg in two weeks on the 25th of October 2024 in the lecture “Topology Optimization and Design Rules for Additive Manufacturing” by Prof. Dr.-Ing. Jens Telgkamp. The presented results are from the submitted master thesis of our Hamburg University of Applied Sciences student Fynn-Henrik Duus with the title: Concept development for the integration of mechanically highly resilient lattice structures in structural optimization using nTop's “implicit field technology” for additive manufacturing processes. The research carried out in this master's thesis was supervised by Prof. Dr.-Ing. Jens Telgkamp as first examiner and Jaco Beckmann as second examiner. If you have any questions or if you would like to attend the nTop presentation on 25th of October 2024 in Hamburg, please do not hesitate to reach out!
