Thesis: AI-based local quality prediction for laser powder bed fusion in Aachen, Deutschland

In cooperation with the Chair of Optical Systems Technology (TOS), the Fraunhofer Institute for Laser Technology ILT—Europe’s leading center for contract research and development in the field of laser technology—is offering the opportunity to write a thesis on the topic: »AI-based local quality prediction for laser powder bed fusion«.

We are currently developing machine learning-based approaches to make the laser powder bed fusion (LPBF) process more efficient and improve its quality. To this end, a scalable database of sensor and process data is being created, which serves as the basis for ML models for component segmentation, strategic path planning and process optimisation. The aim is to enable data-driven solutions for the automated analysis of melt pools, porosity and other quality-relevant parameters in 3D printing.

Be part of change

• You will develop a modular data structure for storing sensor and metadata
• In doing so, you will create a simple surrogate model for mapping quality-related parameters
• For validation purposes, you will conduct initial test series and analyse the results
• Finally, you will check whether the model can reliably predict the parameters of a demonstrator component

What you contribute

• You are studying industrial engineering, physics, computer science, mechanical engineering, computational engineering science or a comparable engineering degree programme
• You are already familiar with programming in Python and have gained initial insights into data science and signal processing
• Your working style is characterised by independence, structure and good organisation

What we offer

Team spirit: Creative, interdisciplinary environment with a motivated team, flat hierarchies, and a casual culture .  
Workplace: Excellent equipment with machines and devices as well as top-notch office facilities.
Co-design: Practice-oriented thesis in an innovative environment of applied research.
Work-life balance: Benefit from flexible working hours based on trust.   
Accessibility: Good transport connections, parking spaces directly in front of the institute, an E-charging station, and a parking garage.

The position is limited in duration until completion of the thesis.
