Slawomir KEDZIORA pursued his studies in applied mechanics at the Lodz University of Technology, where he was awarded a PhD degree in Applied Mechanics in the year 2000. His PhD thesis was titled “Ultimate Load Capacity of Orthotropic Thin-Walled Beams-Columns with Open and Closed Cross-Sections in the Elastic-Plastic Range”. He embarked on his career in the automotive industry as a Reliability Engineer in DELPHI, which was immediately followed by promotion as Senior Experimental Engineer in 2002. Later in 2008, he started working at EATON as an Engineering Specialist in Stress Engineering. In 2013, he was recruited as a Principal Engineer at DNV GL, an esteemed company with its domain in the marine industry.

His activities in the industry were primarily around Reliability and Stress Engineering, with a particular focus on the holistic design of mechanical and civil engineering elements and structures.

With the mammoth task of passing on the knowledge legacy to the forthcoming generations, he joined the University of Luxembourg as an associate professor in the Mechanical Engineering Department under Faculty of Science, Technology and Medicine (FSTM) during the year 2014.

PhD projects

(2014 - 2018), Optimisation Assisted Designing of Mechanical Elements for Direct Metal Laser Sintering, by Thanh Bình CAO.

The project mainly dealt with the optimisation assisted design methods investigations employed to develop mechanical elements for direct metal laser sintering (DLS). These developed elements have higher structural performance than those traditionally designed and were able to be practically produced.

(2018 - present), Korrelative Messtechnik im mikroskopischen Bereich unter Weltraumbedinungen by Mats Bremer
This research project aims to predict, measure and verify the thermal expansion and stress of earth satellite components under space conditions in a test chamber. For this purpose, a suitable measuring system for representing deformations in the micrometre range is to be developed and validated. Afterwards, design standards for optimal component design under space conditions will be derived from obtained results.

(2020 - present) Application of functionally graded lattice structures suitable for additive manufacturing in mechanical parts by Thierry Decker

The research project investigates the benefits of proper implementation of the functionally graded lattice structure for additive manufacturing in mechanical applications. The benefits are reducing noise, vibration, weight, and the improvement of strength and sustainability. The challenge is to design and produce the functionally gradated lattice structure itself. In addition, structural optimisation of these structures to get the most out of them is a more difficult task, particularly if a real complex mechanical part needs to be constructed, not only simple specimens.

Interreg Project

Lead partner: Umwelt-Campus Birkenfeld - Trier University of Applied Sciences
Main partners: Hochschule fur Technik und Wirtschaft des Saarlandes – University of Applied Sciences, Trier University of Applied Sciences, University Luxembourg, Any-Shape.

Industrial partners:

Project description:

Additive manufacturing for metallic parts (3D Metal Printing) gains importance with many process possibilities. The lack of a detailed overview of affordable 3D metal printing technologies and material properties in the function of the employed additive processes makes it difficult for SMEs (small and medium enterprises) to decide on the most economical manufacturing method for their business efficiently. The project ComPrintMetal3D: “Comparison of different 3D metal printing processes depending on the application” aims to evaluate 3D metal printing technologies and provide SMEs in the Greater Region and other interested stakeholders a guideline to educate on the best design and production options. Gathering 4 main partners, the project has a total budget of 1,498,451.78 euros for the period 2020-2022.

First, we will survey the state-of-the-art of the various existing technologies and compare them with each other. Some of them will be chosen and illustrate their applications through design optimisation and manufacturing process investigation using a real case study. A step-by-step guide will be provided and distributed to help companies make future decisions. Furthermore, the knowledge gained will be made available free to the public during the project.

Project cost: EUR 1,498,451.78

ERDF amount: 895 382,21 EUR

ERDF rate: 59.75%.

Claude Wolf and Slawomir Kedziora created Fab@Uni in 2012 in response to the growing interest in 3D printing techniques (additive manufacturing). The motto of the lab facility was to build a facility for research and teaching, which focused on design optimisation of components for additive manufacturing and demonstration of additive manufacturing to students at the University of Luxembourg. Since its establishment, the lab has been growing, helping us educate junior engineers and prepare them for professional life in industry and academia.
